On the future of human-centered robotics

“The new frontier is learning how to design the relationships between people, robots, and infrastructure,” says David Mindell, the Dibner Professor of the History of Engineering and Manufacturing, and a professor of aeronautics and astronautics. “We need new sensors, new software, new ways of architecting systems.” Photo: Len Rubenstein

Science and technology are essential tools for innovation, and to reap their full potential, we also need to articulate and solve the many aspects of today’s global issues that are rooted in the political, cultural, and economic realities of the human world. With that mission in mind, MIT’s School of Humanities, Arts, and Social Sciences has launched The Human Factor — an ongoing series of stories and interviews that highlight research on the human dimensions of global challenges. Contributors to this series also share ideas for cultivating the multidisciplinary collaborations needed to solve the major civilizational issues of our time.

David Mindell, the Frances and David Dibner Professor of the History of Engineering and Manufacturing and Professor of Aeronautics and Astronautics at MIT, researches the intersections of human behavior, technological innovation, and automation. Mindell is the author of five acclaimed books, most recently “Our Robots, Ourselves: Robotics and the Myths of Autonomy” (Viking, 2015). He is also the co-founder of Humatics Corporation, which develops technologies for human-centered automation. SHASS Communications recently asked him to share his thoughts on the relationship of robotics to human activities, and the role of multidisciplinary research in solving complex global issues.

Q: A major theme in recent political discourse has been the perceived impact of robots and automation on the United States labor economy. In your research into the relationship between human activity and robotics, what insights have you gained that inform the future of human jobs, and the direction of technological innovation?

A: In looking at how people have designed, used, and adopted robotics in extreme environments like the deep ocean, aviation, or space, my most recent work shows how robotics and automation carry with them human assumptions about how work gets done, and how technology alters those assumptions. For example, the U.S. Air Force’s Predator drones were originally envisioned as fully autonomous — able to fly without any human assistance. In the end, these drones require hundreds of people to operate.

The new success of robots will depend on how well they situate into human environments. As in chess, the strongest players are often the combinations of human and machine. I increasingly see that the three critical elements are people, robots, and infrastructure — all interdependent.

Q: In your recent book “Our Robots, Ourselves,” you describe the success of a human-centered robotics, and explain why it is the more promising research direction — rather than research that aims for total robotic autonomy. How is your perspective being received by robotic engineers and other technologists, and do you see examples of research projects that are aiming at human-centered robotics?

A: One still hears researchers describe full autonom as the only way to go; often they overlook the multitude of human intentions built into even the most autonomous systems, and the infrastructure that surrounds them. My work describes situated autonomy, where autonomous systems can be highly functional within human environments such as factories or cities. Autonomy as a means of moving through physical environments has made enormous strides in the past ten years. As a means of moving through human environments, we are only just beginning. The new frontier is learning how to design the relationships between people, robots, and infrastructure. We need new sensors, new software, new ways of architecting systems.

Q: What can the study of the history of technology teach us about the future of robotics?

A: The history of technology does not predict the future, but it does offer rich examples of how people build and interact with technology, and how it evolves over time. Some problems just keep coming up over and over again, in new forms in each generation. When the historian notices such patterns, he can begin to ask: Is there some fundamental phenomenon here? If it is fundamental, how is it likely to appear in the next generation? Might the dynamics be altered in unexpected ways by human or technical innovations?

One such pattern is how autonomous systems have been rendered less autonomous when they make their way into real world human environments. Like the Predator drone, future military robots will likely be linked to human commanders and analysts in some ways as well. Rather than eliding those links, designing them to be as robust and effective as possible is a worthy focus for researchers’ attention.

Q: MIT President L. Rafael Reif has said that the solutions to today’s challenges depend on marrying advanced technical and scientific capabilities with a deep understanding of the world’s political, cultural, and economic realities. What barriers do you see to multidisciplinary, sociotechnical collaborations, and how can we overcome them?

A: I fear that as our technical education and research continues to excel, we are building human perspectives into technologies in ways not visible to our students. All data, for example, is socially inflected, and we are building systems that learn from those data and act in the world. As a colleague from Stanford recently observed, go to Google image search and type in “Grandma” and you’ll see the social bias that can leak into data sets — the top results all appear white and middle class.

Now think of those data sets as bases of decision making for vehicles like cars or trucks, and we become aware of the social and political dimensions that we need to build into systems to serve human needs. For example, should driverless cars adjust their expectations for pedestrian behavior according to the neighborhoods they’re in?

Meanwhile, too much of the humanities has developed islands of specialized discourse that is inaccessible to outsiders. I used to be more optimistic about multidisciplinary collaborations to address these problems. Departments and schools are great for organizing undergraduate majors and graduate education, but the old two-cultures divides remain deeply embedded in the daily practices of how we do our work. I’ve long believed MIT needs a new school to address these synthetic, far-reaching questions and train students to think in entirely new ways.

Drones land back to Earth at Xponential 2017

PhoneDrone Ethos, Kickstarter campaign. Credit: xCraft/YouTube

JD Claridge’s story epitomizes the current state of the drone industry. Claridge, founder of xCraft, is best known for being the first contestant on Shark Tank to receive money from all the Sharks – even Kevin O’Leary! Walking the floor of Xponential 2017, the annual convention of the Association for Unmanned Vehicle Systems Integration (AUVSI), Claridge remarked to me how the drone industry has grown up since his TV appearance.

Claridge has gone from pitching cellphone cases that turn into drones (aka phonedrone) to solving mission critical problems. The age of fully autonomous flight is near and the drone industry is finally recovering from the hangover of overhyped Kickstarter videos (see Lily drone’s $34 million fraud). xCraft’s pivot to lightweight, power efficient, enterprise drones is an example of this evolved marketplace. During the three days of Xponential 2017, several far-reaching announcements were made between stalwarts of the tech industry and aviation startups. Claridge introduced me to his new partner, Rajant, which is a leader in industrial wireless networks. xCraft’s latest models utilize Rajant’s mesh networks to launch swarms of drones with one controller. More drones flying simultaneously enables users to maximize the flight time limitations of lithium batteries by covering greater areas within a single mission.

Bob Schena, Rajant’s CEO, said, “Rajant’s network technology now makes it possible for one pilot to operate many aircrafts concurrently, with flight times of 45 minutes. We’re pleased to partner with xCraft and bring more intelligence, mobility and autonomy to UAV communication infrastructures covering greater aerial distances while supporting various drone payloads.”

The battery has been the Achilles heel of the small drone industry since inception. While large winged craft relies heavily on fossil fuels, multirotor battery-operated drones have been plagued with shorter missions of under 45 minutes. Innovators like Claridge are leading the way for a new wave of creative solutions:

Solar Powered Wings 

Solar Powered Wings

Airbus showcased its Zephyr drone products or HAPS (High Altitude Pseudo-Satellite) UAVs using solar-winged craft for power. Zephyr UAVs can fly for months at a time, saving thousands of tons of fuel. The HAPS also offers a number of lightweight payload options from voice communications to persistent internet to real-time surveillance. Airbus was not the only solar solution on display; there were a handful of Chinese upstarts and solar cell purveyors for retrofitting existing aircrafts.

Hybrid Fuel Solutions  

In the Startup Pavilion, William Fredericks of the Advanced Aircraft Company (AAC) demoed a novel technology using a hybrid of diesel fuel and lithium batteries with flexible fixed wings and multirotors, resulting in over 3 hours of flying time. AAC’s prototype, the Hercules (above) is remarkably lightweight and fast. Fredricks is an aircraft designer by trade with 12 designs flying in the air, including NASA’s Greased Lightning that looks remarkably similar to Boeing’s Osprey. The Hercules is available for sale on the company’s website for multiple use cases, including: agricultural, first responders, and package delivery. It is interesting to note that a few rows from Frederick’s booth was his former employer, NASA, promoting their new Autonomy Incubator for “intelligent flight systems” and its “autonomy innovation lab,” (definitely an incubator to watch).

Vertical Take Off & Landing

In addition to hybrid fuel strategies, entrepreneurs are also rethinking the launch procedures. AAC’s Hercules and XCraft’s commercial line of drones vertically takeoff to reduce wind resistance and maximize energy consumption. Australian Startup Iridium Dynamics takes this approach to a new level with astonishing results. Its winged craft, Halo, uses a patent-pending “hover thrust” of its entire craft so its wings actually create the vertical lift to hover with minimal power. The drone also has two rotors to fly horizontally. According to Dion Gonano, Control Systems Engineer, it can fly for over 2 hours. The Halo also lands vertically into a stationary mechanical arm. While the website lists a number of commercial applications for this technology, it was unclear in my discussions with Gonano if they have deployed this technology in real tests.

New Charging Efficiencies

Prior to Xponential, Seattle-based WiBotic announced the closing of its $2.5 seed round to fund its next generation of battery charging technologies. The company has created a novel approach to wireless inductive charging for robotics. Its wireless inductive charging platform includes a patent-pending auto detect feature that can begin recharging once the robot enters the proximity of the base station, even during flight. According to Dr. Ben Waters, (CEO), its charge is faster than traditional solutions presently on the market. Dr. Waters demonstrated for me its suite of software tools that monitor battery performance, providing clients with a complete power management analytics platform. WiBotic is already piloting its technology with leading commercial customers in the energy and security sectors. WiBotic is the first inductive charging platform; other companies have created innovating battery-swapping techniques. Airobotics unique drone storage box that is deployed currently at power plants in Israel, includes a robotic arm, housed inside, that services the robot post flight by switching out the payload and battery:

Reducing Payload Weight

In addition to aircraft design, payload weight is a big factor of battery drain. A growing trend within the industry is miniaturizing the size and cost of the components. Ultimately, the mission of a drone is directly related to the type of payload from cameras for collecting images to precise measurements using Light Detection and Ranging sensors (or Lidar). Lidar is typically deployed in autonomous vehicles to provide the most precise position for the robot in a crowded area, like a self-driving car on the road. However, Lidar is currently extremely expensive and large for many multirotor surveys. Chris Brown of Z-Senz, a former scientist with the The National Institute of Standards and Technology (NIST), hopes to change the landscape of drones with his miniaturized Lidar sensor. Brown’s reduced sensor, SKY1, offers major advantages for size, weight, and power consumption without losing accuracy of high distance sensing. A recent study estimates the Lidar market is expected to exceed $5 billion by 2022, with Velodyne and Quanergy already gaining significant investment. Z-Senz is aiming to be commercially available by 2018.

Lidar is not the only measuring methodology, Global Positioning Solutions (GPS) have been deployed widely. Two of the finalists of the Xponetial Startup Showdown were startups focused on reducing GPS chip sizes and increasing functionality. Inertial Sense has produced a chip the size of a dime that is capable of housing an Inertial Measurement Unit (IMU), Attitude Heading Reference System (AHRS), and GPS-aided Inertial Navigation System (INS). Their website claims that their “advanced algorithms fuse output from MEMs inertial sensors, magnetometers, barometric pressure, and a high-sensitivity GPS (GNSS) receiver to deliver fast, accurate, and reliable attitude, velocity, and position even in the most dynamic environments.” The chips and micro navigation accessories are available on the company’s e-store.

The winner of the Showdown, uAvionix, is a leading developer of avionics for both manned and unmanned flight. Their new transceivers and transponders claim to be “the smallest, and lightest and most affordable on the market” (already GPS is a commodity). uAvionix presented its “Ping Network System that reduces weight on average by 40% as compared to the two-piece installations.” The Ping products also claim barometric altitude precision with accuracy beyond 80,000 ft.

Paul Beard, CEO of uAvionix, said, “our customers have asked for even smaller and lighter solutions; integrating the transceivers, GPS receivers, GPS antennas, and barometric pressure sensors into a single form factor facilitates easier installation and lowers weight and power draw requirements resulting in a longer usable flight time.”

As I rushed to the airport to catch my manned flight, I felt reenergized about the drone industry, although follies will persist. I mean who wouldn’t want a pool deckchair drone this summer?

This and all other autonomous subjects will be explored at RobotLabNYC’s next event with Dr. Howard Morgan (FirstRound Capital) and Tom Ryden (MassRobotics) – RSVP.

Classroom robotics: Training teachers to code

*All images credit: ROBBO

30 teachers arrived, excited to learn. They rolled up their sleeves and placed laptops and Robot kits on the floor. The room filled with excitement (and laughter!) as everyone tried to come up with different solutions on how to create different programs. The results were hilarious; a robot inspired by Darth Vader, a robot that asked everyone to turn the lights off when it was too bright in the room, and a robot that tricked the teacher to leave the classroom during an exam.

Not bad for a day of “work!”

Training, like above, is what we’re all about at ROBBO. ROBBO is a fun and simple way for absolutely anyone to get introduced to the world of robotics and coding. As a part of one of our many projects, we organized a training weekend for the single purpose of introducing teachers to programming and robotics. The teachers started with simple exercises in RobboScratch, a visual programming environment; moving the character, creating series of multiple commands, and learning the advantages of the infinite loop when making programs.

So, what do we mean about classroom robotics? Our educational robotics consist of two different robots; the Robot kit and the Lab. Both robots are ideal for learning programming, robotics as well as skills in problem-solving, mathematics and physics while working in interactive teams. The Lab includes a microphone, LED-lights, light sensor and a slider and is great for experimenting with different elements such as sound or light and numeric values. Our other robot is the Robot kit, equipped with a motor, which is a fun way to explore everyday technology using a touch sensor, proximity sensor, light sensor, line sensors and an LED-light. Our robots are programmed in the visual programming environment RobboScratch, an adapted version of Scratch developed at MIT.

In our earlier example, teachers were divided into separate workshops, working in pairs, or teams of three. We believe it is important to communicate and discuss with others to better understand different programs and come up with alternative solutions if the program doesn’t work in the desired way. The workshops are all based on the exercises from our pedagogical guide, and teachers were given a copy of the guide for their own use. Our guide provides instructions and multiple exercise card (with solutions!) and is free to download here (http://robbo.world/support/).

Our teaching guide is for anyone who wants to learn the basics of programming with the help of ROBBO™ robotics and RobboScratch. Our pedagogical guide is a comprehensive educational tool with instructions, exercise cards and ideas for creating the ultimate learning experience. It has been developed together with Innokas Network at the University of Helsinki and Finnish teachers and students. The majority of the teachers that participated in the training had only limited knowledge of Scratch or Scratch Junior and, therefore, we started from the beginning.

The pedagogical guide includes an introduction to RobboScratch, Lab and Robot kit as well as up to 28 exercise cards to help you along the way. The exercises are designed to develop necessary programming skills step by step, teaching children to think logically as a software developer would do, which may also be useful in many everyday situations. These are, in particular, the ability to understand the whole, to split a problem into smaller parts, and to develop a simple program to perform an operation. In the initial exercises, students will make a program using a predefined model, but as the practice progresses, they will have more and more space for their own ideas.

By developing new skills, users are encouraged to plan and develop innovations in robotics. The training goal is to learn understand and use technology to invent something new. As the final assignment of the teachers’ training, we asked teachers to form teams of four and come up with a small prank using the different capabilities and sensors of either Robot kit or Lab or simultaneous use of both robots.

If you’d like to to learn more about ROBBO or download our free guide, visit our website: http://robbo.world/support/

Comments from teachers:

“The teaching guide is a great support when learning coding. And I can just hand out these ready-made exercise cards to my students as well!”

“The exercise in the guide are good for understanding the different possibilities you have with the robots, because when you start doing an exercise you come up with more ideas on how to develop a more complicated program.”

“The robots emphasized practicality in the learning process. In addition to programming, ROBBO teaches environmental studies and all-around useful skills, in particular when the exercises of the pedagogical guide are being utilized.”

Engineers design “tree-on-a-chip”

Engineers have designed a microfluidic device they call a “tree-on-a-chip,” which mimics the pumping mechanism of trees and other plants.

Trees and other plants, from towering redwoods to diminutive daisies, are nature’s hydraulic pumps. They are constantly pulling water up from their roots to the topmost leaves, and pumping sugars produced by their leaves back down to the roots. This constant stream of nutrients is shuttled through a system of tissues called xylem and phloem, which are packed together in woody, parallel conduits.

Now engineers at MIT and their collaborators have designed a microfluidic device they call a “tree-on-a-chip,” which mimics the pumping mechanism of trees and plants. Like its natural counterparts, the chip operates passively, requiring no moving parts or external pumps. It is able to pump water and sugars through the chip at a steady flow rate for several days. The results are published this week in Nature Plants.

Anette “Peko” Hosoi, professor and associate department head for operations in MIT’s Department of Mechanical Engineering, says the chip’s passive pumping may be leveraged as a simple hydraulic actuator for small robots. Engineers have found it difficult and expensive to make tiny, movable parts and pumps to power complex movements in small robots. The team’s new pumping mechanism may enable robots whose motions are propelled by inexpensive, sugar-powered pumps.

“The goal of this work is cheap complexity, like one sees in nature,” Hosoi says. “It’s easy to add another leaf or xylem channel in a tree. In small robotics, everything is hard, from manufacturing, to integration, to actuation. If we could make the building blocks that enable cheap complexity, that would be super exciting. I think these [microfluidic pumps] are a step in that direction.”

Hosoi’s co-authors on the paper are lead author Jean Comtet, a former graduate student in MIT’s Department of Mechanical Engineering; Kaare Jensen of the Technical University of Denmark; and Robert Turgeon and Abraham Stroock, both of Cornell University.

A hydraulic lift

The group’s tree-inspired work grew out of a project on hydraulic robots powered by pumping fluids. Hosoi was interested in designing hydraulic robots at the small scale, that could perform actions similar to much bigger robots like Boston Dynamic’s Big Dog, a four-legged, Saint Bernard-sized robot that runs and jumps over rough terrain, powered by hydraulic actuators.

“For small systems, it’s often expensive to manufacture tiny moving pieces,” Hosoi says. “So we thought, ‘What if we could make a small-scale hydraulic system that could generate large pressures, with no moving parts?’ And then we asked, ‘Does anything do this in nature?’ It turns out that trees do.”

The general understanding among biologists has been that water, propelled by surface tension, travels up a tree’s channels of xylem, then diffuses through a semipermeable membrane and down into channels of phloem that contain sugar and other nutrients.

The more sugar there is in the phloem, the more water flows from xylem to phloem to balance out the sugar-to-water gradient, in a passive process known as osmosis. The resulting water flow flushes nutrients down to the roots. Trees and plants are thought to maintain this pumping process as more water is drawn up from their roots.

“This simple model of xylem and phloem has been well-known for decades,” Hosoi says. “From a qualitative point of view, this makes sense. But when you actually run the numbers, you realize this simple model does not allow for steady flow.”

In fact, engineers have previously attempted to design tree-inspired microfluidic pumps, fabricating parts that mimic xylem and phloem. But they found that these designs quickly stopped pumping within minutes.

It was Hosoi’s student Comtet who identified a third essential part to a tree’s pumping system: its leaves, which produce sugars through photosynthesis. Comtet’s model includes this additional source of sugars that diffuse from the leaves into a plant’s phloem, increasing the sugar-to-water gradient, which in turn maintains a constant osmotic pressure, circulating water and nutrients continuously throughout a tree.

Running on sugar

With Comtet’s hypothesis in mind, Hosoi and her team designed their tree-on-a-chip, a microfluidic pump that mimics a tree’s xylem, phloem, and most importantly, its sugar-producing leaves.

To make the chip, the researchers sandwiched together two plastic slides, through which they drilled small channels to represent xylem and phloem. They filled the xylem channel with water, and the phloem channel with water and sugar, then separated the two slides with a semipermeable material to mimic the membrane between xylem and phloem. They placed another membrane over the slide containing the phloem channel, and set a sugar cube on top to represent the additional source of sugar diffusing from a tree’s leaves into the phloem. They hooked the chip up to a tube, which fed water from a tank into the chip.

With this simple setup, the chip was able to passively pump water from the tank through the chip and out into a beaker, at a constant flow rate for several days, as opposed to previous designs that only pumped for several minutes.

“As soon as we put this sugar source in, we had it running for days at a steady state,” Hosoi says. “That’s exactly what we need. We want a device we can actually put in a robot.”

Hosoi envisions that the tree-on-a-chip pump may be built into a small robot to produce hydraulically powered motions, without requiring active pumps or parts.

“If you design your robot in a smart way, you could absolutely stick a sugar cube on it and let it go,” Hosoi says.

This research was supported, in part, by the Defense Advance Research Projects Agency.

Worm-inspired material strengthens, changes shape in response to its environment

A new material that naturally adapts to changing environments was inspired by the strength, stability, and mechanical performance of the jaw of a marine worm. The protein material, which was designed and modeled by researchers from the Laboratory for Atomistic and Molecular Mechanics (LAMM) in the Department of Civil and Environmental Engineering (CEE), and synthesized in collaboration with the Air Force Research Lab (AFRL) at Wright-Patterson Air Force Base, Ohio, expands and contracts based on changing pH levels and ion concentrations. It was developed by studying how the jaw of Nereis virens, a sand worm, forms and adapts in different environments.

The resulting pH- and ion-sensitive material is able to respond and react to its environment. Understanding this naturally-occurring process can be particularly helpful for active control of the motion or deformation of actuators for soft robotics and sensors without using external power supply or complex electronic controlling devices. It could also be used to build autonomous structures.

“The ability of dramatically altering the material properties, by changing its hierarchical structure starting at the chemical level, offers exciting new opportunities to tune the material, and to build upon the natural material design towards new engineering applications,” wrote Markus J. Buehler, the McAfee Professor of Engineering, head of CEE, and senior author of the paper.

The research, recently published in ACS Nano, shows that depending on the ions and pH levels in the environment, the protein material expands and contracts into different geometric patterns. When the conditions change again, the material reverts back to its original shape. This makes it particularly useful for smart composite materials with tunable mechanics and self-powered roboticists that use pH value and ion condition to change the material stiffness or generate functional deformations.

Finding inspiration in the strong, stable jaw of a marine worm

In order to create bio-inspired materials that can be used for soft robotics, sensors, and other uses — such as that inspired by the Nereis — engineers and scientists at LAMM and AFRL needed to first understand how these materials form in the Nereis worm, and how they ultimately behave in various environments. This understanding involved the development of a model that encompasses all different length scales from the atomic level, and is able to predict the material behavior. This model helps to fully understand the Nereis worm and its exceptional strength.

“Working with AFRL gave us the opportunity to pair our atomistic simulations with experiments,” said CEE research scientist Francisco Martin-Martinez. AFRL experimentally synthesized a hydrogel, a gel-like material made mostly of water, which is composed of recombinant Nvjp-1 protein responsible for the structural stability and impressive mechanical performance of the Nereis jaw. The hydrogel was used to test how the protein shrinks and changes behavior based on pH and ions in the environment.

The Nereis jaw is mostly made of organic matter, meaning it is a soft protein material with a consistency similar to gelatin. In spite of this, its strength, which has been reported to have a hardness ranging between 0.4 and 0.8 gigapascals (GPa), is similar to that of harder materials like human dentin. “It’s quite remarkable that this soft protein material, with a consistency akin to Jell-O, can be as strong as calcified minerals that are found in human dentin and harder materials such as bones,” Buehler said.

At MIT, the researchers looked at the makeup of the Nereis jaw on a molecular scale to see what makes the jaw so strong and adaptive. At this scale, the metal-coordinated crosslinks, the presence of metal in its molecular structure, provide a molecular network that makes the material stronger and at the same time make the molecular bond more dynamic, and ultimately able to respond to changing conditions. At the macroscopic scale, these dynamic metal-protein bonds result in an expansion/contraction behavior.

Combining the protein structural studies from AFRL with the molecular understanding from LAMM, Buehler, Martin-Martinez, CEE Research Scientist Zhao Qin, and former PhD student Chia-Ching Chou ’15, created a multiscale model that is able to predict the mechanical behavior of materials that contain this protein in various environments. “These atomistic simulations help us to visualize the atomic arrangements and molecular conformations that underlay the mechanical performance of these materials,” Martin-Martinez said.

Specifically, using this model the research team was able to design, test, and visualize how different molecular networks change and adapt to various pH levels, taking into account the biological and mechanical properties.

By looking at the molecular and biological makeup of a the Nereis virens and using the predictive model of the mechanical behavior of the resulting protein material, the LAMM researchers were able to more fully understand the protein material at different scales and provide a comprehensive understanding of how such protein materials form and behave in differing pH settings. This understanding guides new material designs for soft robots and sensors.

Identifying the link between environmental properties and movement in the material

The predictive model explained how the pH sensitive materials change shape and behavior, which the researchers used for designing new PH-changing geometric structures. Depending on the original geometric shape tested in the protein material and the properties surrounding it, the LAMM researchers found that the material either spirals or takes a Cypraea shell-like shape when the pH levels are changed. These are only some examples of the potential that this new material could have for developing soft robots, sensors, and autonomous structures.

Using the predictive model, the research team found that the material not only changes form, but it also reverts back to its original shape when the pH levels change. At the molecular level, histidine amino acids present in the protein bind strongly to the ions in the environment. This very local chemical reaction between amino acids and metal ions has an effect in the overall conformation of the protein at a larger scale. When environmental conditions change, the histidine-metal interactions change accordingly, which affect the protein conformation and in turn the material response.

“Changing the pH or changing the ions is like flipping a switch. You switch it on or off, depending on what environment you select, and the hydrogel expands or contracts” said Martin-Martinez.

LAMM found that at the molecular level, the structure of the protein material is strengthened when the environment contains zinc ions and certain pH levels. This creates more stable metal-coordinated crosslinks in the material’s molecular structure, which makes the molecules more dynamic and flexible.

This insight into the material’s design and its flexibility is extremely useful for environments with changing pH levels. Its response of changing its figure to changing acidity levels could be used for soft robotics. “Most soft robotics require power supply to drive the motion and to be controlled by complex electronic devices. Our work toward designing of multifunctional material may provide another pathway to directly control the material property and deformation without electronic devices,” said Qin.

By studying and modeling the molecular makeup and the behavior of the primary protein responsible for the mechanical properties ideal for Nereis jaw performance, the LAMM researchers are able to link environmental properties to movement in the material and have a more comprehensive understanding of the strength of the Nereis jaw.

The research was funded by the Air Force Office of Scientific Research and the National Science Foundation’s Extreme Science and Engineering Discovery Environment (XSEDE) for the simulations.

Living and working with robots: European Robotics Forum to focus on robotics markets and future of work

Over 800 leading scientists, companies, and policymakers working in robotics will convene at the European Robotics Forum (#ERF2017) in Edinburgh, 22-24 March. This year’s theme is “Living and Working With Robots” with a focus on applications in manufacturing, disaster relief, agriculture, healthcare, assistive living, education, and mining.

The 3-day programme features keynotes, panel discussions, workshops, and plenty of robots roaming the exhibit floor. Visitors may encounter a humanoid from Pal Robotics, a bartender robot from KUKA, Shadow’s human-like hands, or the latest state-of-the-art robots from European research. Success stories from Horizon 2020, the European Union’s framework programme for research and innovation, and FP7 European projects will be on display.

Dr Cécile Huet Deputy Head of European Commission Robotics & Artificial Intelligence Unit, said, “A set of EU projects will demonstrate the broad impact of the EU funding programme in robotics: from progress in foundational research in robot learning, to in touch sensing for a new dimension in intuitive Human-Robot cooperation, to inspection in the oil-and-gas industry, security, care, manufacturing for SMEs, or the vast applications enabled by the progress in drones autonomous navigation.”

Reinhard Lafrenz, Secretary General of euRobotics said, “A rise in sales in robotics is driving the industry forward, and it’s not just benefiting companies who sell robots, but also SMEs and larger industries that use robots to increase their productivity and adopt new ways of thinking about their business. Around 80 robotics start-ups were created last year in Europe, which is truly remarkable. At euRobotics, we nurture the robotics industry ecosystem in Europe; keep an eye out for the Tech Transfer award and the Entrepreneurship award we’ll be giving out at ERF.”

Projects presented will include:

  • FUTURA – Focused Ultrasound Therapy Using Robotic Approaches
  • PETROBOT – Use cases for inspection robots opening up the oil-, gas- and petrochemical markets
  • sFly – Swarm of Micro Flying Robots
  • SMErobotics – The European Robotics Initiative for Strengthening the Competitiveness of SMEs in Manufacturing by Integrating aspects of Cognitive Systems
  • STRANDS – Spatio-Temporal Representations and Activities For Cognitive Control in Long-Term Scenarios
  • WEARHAP – WEARable HAPtics for Humans and Robots
  • Xperience – Robots Bootstrapped through Learning from Experience

The increased use of Artificial Intelligence and Machine Learning in robotics will be highlighted in two keynote presentations. Raia Hadsell, Senior Research Scientist at DeepMind will focus on deep learning, and strategies to make robots that can continuously learn and improve over time. Stan Boland, CEO of FiveAI, will talk about his company’s aim to accelerate the arrival of fully autonomous vehicles.

Professor David Lane, ERF2017 General Chair and Director of the Edinburgh Centre for Robotics, said,  “We’re delighted this year to have two invited keynotes of outstanding quality and relevance from the UK, representing both research and disruptive industrial application of robotics and artificial intelligence. EURobotics and its members are committed to the innovation that translates technology from research to new products and services. New industries are being created, with robotics providing the essential arms, legs and sensors that bring big data and artificial intelligence out of the laboratory and into the real world.”

Throughout ERF2017, emphasis will be given to the impact of robots on society and the economy. Keith Brown MSP, Cabinet Secretary for Economy, Jobs and Fair Work, will open the event, said, “The European Robotics Forum provides an opportunity for Scotland to showcase our world-leading research and expertise in robotics, artificial intelligence and human-robot interaction. This event will shine a light on some of the outstanding developments being pioneered and demonstrates Scotland’s vital role in this globally significant area.”

In discussing robots and society, Dr Patricia A. Vargas, ERF2017 General Chair and Director of the Robotics Laboratory at Heriot-Watt University, said, “As robots gradually move to our homes and workplace, we must make sure they are fully ethical. A potential morality code for robots should include human responsibilities, and take into account how humans can interact with robots in a safe way. The European Robotics Forum is the ideal place to drive these discussions.”

Ultimately, the forum aims to understand how robots can benefit small and medium-sized businesses, and how links between industry and academia can be improved to better exploit the strength of European robotics and AI research. As robots start leaving the lab to enter our home and work environments, it becomes increasingly important to understand how they will best work alongside human co-workers and users. Issues of policy, the law, and ethics will be debated during dedicated workshops.

Dr Katrin Lohan, General Chair and Deputy Director of the Robotics Laboratory at Heriot-Watt University said, “It is important how to integrate robotics into the workflow so that it support and not disrupt the human workers. The potential of natural interaction interfaces and non-verbal communication cues needs to be further explored. The synergies of robots and human workers could make all the difference for small and medium-sized businesses to discuss this the European Robotics Forum is the ideal place as it joins industry and academia community. ”

RoboThespian stars in UK play Spillikin, a love story

In a poignant play traveling throughout the UK, a robot is co-star and companion to the wife of the (now deceased) robot builder, with the wife developing early Alzheimer’s. The play explores very human themes about love, death, and disease, all handled extremely sensitively with RoboThespian playing a large role.

Jon Welch, the writer and director, said of the play:

“It’s a story about a robot maker. All of his life he builds robots, but he develops degenerative illness in mid-life and realizes he’s not going to live to remain a companion to his wife. His wife, by now, is developing early Alzheimer’s, so he builds his final creation, his final robot to be a companion to his wife.”

The robot is from Engineered Arts, a 12-year-old UK company that develops an ever expanding range of humanoid and semi-humanoid robots featuring natural human-like movement and advanced social behaviours. RoboThespian, Socibot and Byrun are their most prominent robot creations.

“We have pre-programmed every single thing the robot says and every single thing the robot does — all the moves. There’s about nearly 400 separate queues but they are made up of other files, all stuck together so there’s probably a couple of thousand cues in reality. So the robot will always say the same thing and move the same way, depending on what queue is been triggered at what particular time.”

This promotional video for the play is well worth watching:

Bosch and Nvidia partner to develop AI for self-driving cars

Amongst all the activity in autonomously driven vehicle joint ventures, new R&D facilities, strategic acquisitions (such as Mobileye being acquired by Intel) and booming startup fundings, two big players in the industry, NVIDIA and Bosch, are partnering to develop an AI self-driving car supercomputer.

Bosch CEO Dr Volkmar Denner announced the partnership during his keynote address at Bosch Connected World, in Berlin.

“Automated driving makes roads safer, and artificial intelligence is the key to making that happen,” said Denner. “We are making the car smart. We are teaching the car how to maneuver through road traffic by itself.”

The Bosch AI car computer will use NVIDIA AI PX technology, the upcoming AI car superchip, advertised as the world’s first single-chip processor designed to achieve Level-4 autonomous driving (see ADAS chart). The unprecedented level of performance is necessary to handle the massive amount of computation required for the various tasks self-driving vehicles must perform which include running deep neural nets to sense surroundings, understanding the 3D environment, localizing themselves on an HD map, predicting the behavior and position of other objects, as well as computing car dynamics and a safe path forward.

Essentially, the NVIDIA platform enables vehicles to be trained on the complexities of driving, operated autonomously and updated over the air with new features and capabilities. And Bosch, which is the one of the world’s largest auto parts makers, has the Tier 1 credentials to mass-produce this AI-enabled supercomputer for a good portion of the auto industry.

“Self-driving cars is a challenge that can finally be solved with recent breakthroughs in deep learning and artificial intelligence,” said Jen-Hsun Huang, founder and CEO, NVIDIA. “Using DRIVE PX AI car computer, Bosch will build automotive-grade systems for the mass production of autonomous cars. Together we will realize a future where autonomous vehicles make mobility safe and accessible to all.”

Nvidia is also partnering with automakers Audi and Mercedes-Benz.

Bottom line:

“This is the kind of strategic tie-up that lets both partners do what they do best – Nvidia can focus on developing the core AI supercomputing tech, and Bosch can provide relationships and sales operations that offer true scale and reach,” says Darrell Etherington for TechCrunch.

Security for multirobot systems

Researchers including MIT professor Daniela Rus (left) and research scientist Stephanie Gil (right) have developed a technique for preventing malicious hackers from commandeering robot teams’ communication networks. To verify the theoretical predictions, the researchers implemented their system using a battery of distributed Wi-Fi transmitters and an autonomous helicopter. Image: M. Scott Brauer.

Distributed planning, communication, and control algorithms for autonomous robots make up a major area of research in computer science. But in the literature on multirobot systems, security has gotten relatively short shrift.

In the latest issue of the journal Autonomous Robots, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory and their colleagues present a new technique for preventing malicious hackers from commandeering robot teams’ communication networks. The technique could provide an added layer of security in systems that encrypt communications, or an alternative in circumstances in which encryption is impractical.

“The robotics community has focused on making multirobot systems autonomous and increasingly more capable by developing the science of autonomy. In some sense we have not done enough about systems-level issues like cybersecurity and privacy,” says Daniela Rus, an Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT and senior author on the new paper.

“But when we deploy multirobot systems in real applications, we expose them to all the issues that current computer systems are exposed to,” she adds. “If you take over a computer system, you can make it release private data — and you can do a lot of other bad things. A cybersecurity attack on a robot has all the perils of attacks on computer systems, plus the robot could be controlled to take potentially damaging action in the physical world. So in some sense there is even more urgency that we think about this problem.”

Identity theft

Most planning algorithms in multirobot systems rely on some kind of voting procedure to determine a course of action. Each robot makes a recommendation based on its own limited, local observations, and the recommendations are aggregated to yield a final decision.

A natural way for a hacker to infiltrate a multirobot system would be to impersonate a large number of robots on the network and cast enough spurious votes to tip the collective decision, a technique called “spoofing.” The researchers’ new system analyzes the distinctive ways in which robots’ wireless transmissions interact with the environment, to assign each of them its own radio “fingerprint.” If the system identifies multiple votes as coming from the same transmitter, it can discount them as probably fraudulent.

“There are two ways to think of it,” says Stephanie Gil, a research scientist in Rus’ Distributed Robotics Lab and a co-author on the new paper. “In some cases cryptography is too difficult to implement in a decentralized form. Perhaps you just don’t have that central key authority that you can secure, and you have agents continually entering or exiting the network, so that a key-passing scheme becomes much more challenging to implement. In that case, we can still provide protection.

“And in case you can implement a cryptographic scheme, then if one of the agents with the key gets compromised, we can still provide  protection by mitigating and even quantifying the maximum amount of damage that can be done by the adversary.”

Hold your ground

In their paper, the researchers consider a problem known as “coverage,” in which robots position themselves to distribute some service across a geographic area — communication links, monitoring, or the like. In this case, each robot’s “vote” is simply its report of its position, which the other robots use to determine their own.

The paper includes a theoretical analysis that compares the results of a common coverage algorithm under normal circumstances and the results produced when the new system is actively thwarting a spoofing attack. Even when 75 percent of the robots in the system have been infiltrated by such an attack, the robots’ positions are within 3 centimeters of what they should be. To verify the theoretical predictions, the researchers also implemented their system using a battery of distributed Wi-Fi transmitters and an autonomous helicopter.

“This generalizes naturally to other types of algorithms beyond coverage,” Rus says.

The new system grew out of an earlier project involving Rus, Gil, Dina Katabi — who is the other Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT — and Swarun Kumar, who earned master’s and doctoral degrees at MIT before moving to Carnegie Mellon University. That project sought to use Wi-Fi signals to determine transmitters’ locations and to repair ad hoc communication networks. On the new paper, the same quartet of researchers is joined by MIT Lincoln Laboratory’s Mark Mazumder.

Typically, radio-based location determination requires an array of receiving antennas. A radio signal traveling through the air reaches each of the antennas at a slightly different time, a difference that shows up in the phase of the received signals, or the alignment of the crests and troughs of their electromagnetic waves. From this phase information, it’s possible to determine the direction from which the signal arrived.

Space vs. time

A bank of antennas, however, is too bulky for an autonomous helicopter to ferry around. The MIT researchers found a way to make accurate location measurements using only two antennas, spaced about 8 inches apart. Those antennas must move through space in order to simulate measurements from multiple antennas. That’s a requirement that autonomous robots meet easily. In the experiments reported in the new paper, for instance, the autonomous helicopter hovered in place and rotated around its axis in order to make its measurements.

When a Wi-Fi transmitter broadcasts a signal, some of it travels in a direct path toward the receiver, but much of it bounces off of obstacles in the environment, arriving at the receiver from different directions. For location determination, that’s a problem, but for radio fingerprinting, it’s an advantage: The different energies of signals arriving from different directions give each transmitter a distinctive profile.

There’s still some room for error in the receiver’s measurements, however, so the researchers’ new system doesn’t completely ignore probably fraudulent transmissions. Instead, it discounts them in proportion to its certainty that they have the same source. The new paper’s theoretical analysis shows that, for a range of reasonable assumptions about measurement ambiguities, the system will thwart spoofing attacks without unduly punishing valid transmissions that happen to have similar fingerprints.

“The work has important implications, as many systems of this type are on the horizon — networked autonomous driving cars, Amazon delivery drones, et cetera,” says David Hsu, a professor of computer science at the National University of Singapore. “Security would be a major issue for such systems, even more so than today’s networked computers. This solution is creative and departs completely from traditional defense mechanisms.”

Collaborating machines and avoiding soil compression

Image: Swarmfarm

Soil compression can be a serious problem, but it isn’t always, or in all ways, a bad thing. For example, impressions made by hoofed animals, so long as they only cover a minor fraction of the soil surface, create spaces in which water can accumulate and help it percolate into the soil more effectively, avoiding erosion runoff.

The linear depressions made by wheels rolling across the surface are more problematic because they create channels that can accelerate the concentration of what would otherwise be evenly distributed rainfall, turning it into a destructive force. This is far less serious when those wheels follow the contour of the land rather than running up and down slopes.

Taking this one step further, if it is possible for wheeled machines to always follow the same tracks, the compression is localized and the majority of the land area remains unaffected. If those tracks are filled with some material though which water can percolate but which impedes the accumulation of energy in downhill flows, the damage is limited to the sacrifice of the portion of the overall land area dedicated to those tracks and the creation of compression zones beneath them, which may result in boggy conditions on the uphill sides of the tracks, which may or may not be a bad thing, depending on what one is trying to grow there.

(I should note at this point that such tracks, when they run on the contour, are reminiscent of the ‘swales’ used in permaculture and regenerative agriculture.)

Tractors with GPS guidance are capable of running their wheels over the same tracks with each pass, but the need for traction, so they can apply towing force to implements running through the soil, means that those tracks will constitute a significant percentage of the overall area. Machines, such as dedicated sprayers, with narrower wheels that can be spread more widely apart, create tracks which occupy far less of the total land area, but they are not built for traction, and using them in place of tractors for all field operations would require a very different approach to farming.

It is possible to get away from machine-caused soil compression altogether, using either aerial machines (drones) or machines which are supported by or suspended from fixed structures, like posts or rails.

Small drones are much like hummingbirds in that they create little disturbance, but they are also limited in the types of operations they can perform by their inability to carry much weight or exert significant force. They’re fine for pollination but you wouldn’t be able to use them to uproot weeds with tenacious roots or to harvest watermelons or pumpkins.

On the other hand, fixed structures and the machines that are supported by or suspended from them have a significant up-front cost. In the case of equipment suspended from beams or gantries spanning between rails and supported from wheeled trucks which are themselves supported by rails, there is a tradeoff between the spacing of the rails and the strength/stiffness required in the gantry. Center-pivot arrangements also have such a tradeoff, but they use a central pivot in place of one rail (or wheel track), and it’s common for them to have several points of support spaced along the beam, requiring several concentric rails or wheel tracks.

Strictly speaking, there’s no particular advantage in having rail-based systems follow the contour of the land since they leave no tracks at all. Center-pivot systems using wheels that run directly on the soil rather than rail are best used on nearly flat ground since their round tracks necessarily run downhill over part of their circumference. In any rail-based system, the “rail” might be part of the mobile unit rather than part of the fixed infrastructure, drawing support from posts spaced closely enough that there were always at least two beneath it. However, this would preclude using trough-shaped rails to deliver water for irrigation.

Since the time of expensive machines is precious, it’s best to avoid burdening them with operations that can be handled by small, inexpensive drones, and the ideal arrangement is probably a combination of small drones, a smaller number of larger drones with some carrying capacity, light on-ground devices that put little pressure on the soil, and more substantial machines supported or suspended from fixed infrastructure, whether rail, center-pivot, or something else. Livestock (chickens, for example), outfitted with light wearable devices, might also be part of the mix.

The small drones, being more numerous, will be the best source of raw data, which can be used to optimize the operation of the larger drones, on-ground devices, and the machines mounted on fixed infrastructure, although too much centralized control would not be efficient. Each device should be capable of continuing to do useful work even when it loses network connection, and peer-to-peer connections will be more appropriate than running everything through a central hub in some circumstances.

This is essentially a problem in complex swarm engineering, complex because of the variety of devices involved. Solving it in a way that creates a multi-device platform capable of following rules, carrying out plans, and recognizing anomalous conditions is the all-important first step in enabling the kind of robotics that can then go one to enable regenerative practices in farming (and land management in general).
