As more commercial drone users take to the sky, insurers are struggling to develop policies to cover the eventualities of flying. Meanwhile, insurance companies also want to fly drones themselves for appraisals and damage assessments. We spoke with Tom Karol, general counsel-federal for the National Association of Mutual Insurance Companies, to learn about the uncertain landscape that is the drone insurance industry.

News

Pakistan criticized the U.S. government for a drone strike that killed Mullah Akhtar Mansour, the leader of the Afghan Taliban. In a statement, Sartaj Aziz, foreign affairs special adviser to Pakistani Prime Minister Nawaz Sharif, said that the strike undermined attempts to negotiate a peace deal with the Taliban. “Pakistan believes that politically negotiated settlement remains the most viable option for bringing lasting peace to Afghanistan,” Aziz said.

The US just moved a step closer to building an advanced robotics institute modeled on the hugely successful Fraunhofer Institutes. The proposed ARM or Advanced Robotics Manufacturing Institute is one of seven candidates moving forward in an open bid for $70 million funding from NIST for an innovation institute to join the National Network for Manufacturing Innovation. Previously funded institutes are for advanced composites, flexible electronics, digital and additive manufacturing, semiconductor technology, textiles and photonics.

The ARM Institute bid is being led by Georgia Tech and CMU, alongside several other universities, including MIT, RPI, USC, UPENN, TAMU and UC Berkeley. At a recent ‘industry day’ at UC Berkeley on May 25, an invitation was extended to “all companies, regional economic development organizations, colleges and universities, government representatives and non-­profit groups with interests in advanced and collaborative robotics industry to participate in this initiative to ensure the competitiveness of US robotics and thereby enhance the quality of life of our citizens.”

Industry participation is critical to the success of the ARM institute. Industry is expected to provide matching funding to the NIST grant, but also strategically to provide guidance in setting the priorities of the initiative. Currently defined as:

  • Collaborative Robotics
  • Rapid Deployment of Flexible Robotic Manufacturing
  • Low-cost Mass Production in Quantities of One

The vision is to create a national resource of manufacturing research and solutions, linking regional hubs and manufacturing centers. An important component of this vision is providing a pathway for SMEs and startups to connect with established industry and research partners.

How is Pepper, SoftBank’s emotional robot, doing?

Source: Getty Images
Source: Getty Images

Pepper is a child-height human-shaped robot described as having been designed to be a genuine companion that perceives and acts upon a range of human emotions.

SoftBank, the Japanese telecom giant, acquired Aldebaran Robotics and commissioned the development of Pepper. Subsequently SoftBank joint ventured with Alibaba and Foxconn to form a development, production and marketing entity for the robots. There has been much fanfare about Pepper, particularly about its ability to use its body movement and tone of voice to communicate in a way designed to feel natural and intuitive.

The number of Peppers sold to date is newsworthy. As of today, there are likely close to 10,000 Peppers out in the world. Online sales have been 1,000 units each month for the last seven months with additional sales to businesses such as Nestle for their coffee shops and SoftBank for their telecom stores.

At around $1,600 per robot, 10,000 robots equates to $16 million in sales but Peppers are sold on a subscription contract that includes a network data plan and equipment insurance. This costs $360 per month and, over 36 months, brings the total cost of ownership to over $14,000. Consequently many are asking what Peppers are being used for, how they are being perceived, and whether they are useful? Essentially, how is Pepper doing? Does it offer value for money spent?

Two recent videos provide a window into Pepper’s state of development.

FINANCIAL TIMES

In a promotional effort, Pepper and a SoftBank publicity team came to the London offices of the Financial Times for an introduction and visit. This video shows one reporter’s attempt to understand Pepper’s capabilities and interactive abilities.

People in the FT offices were definitely attracted, amused and happy with the initial experience of being introduced to Pepper. They laughed at Peppers failures and patted its head to make it feel better. But, Pepper failed in every way to (1) be a companion, (2) recognize emotional cues, (3) be able to converse reliably and intelligently, and (4) provide any level of service other than first-time entertainment.

MASTERCARD

MasterCard unveiled the first application of their MasterPass digital payment service by a robot. It will be rolled out in Pizza Hut restaurants in Asia on Pepper robot order-takers beginning in Q4 2016. To accentuate the hook-up, MasterCard created this video showing what they hope will be a typical interaction involved in Pepper taking a customer’s order.

Tobias Puehse, vice president, innovation management, Digital Payments & Labs at MasterCard, said of the venture with SoftBank and Pepper bots:

“The app’s goal is to provide consumers with more memorable and personalized shopping experience beyond today’s self-serve machines and kiosks, by combining Pepper’s intelligence with a secure digital payment experience via MasterPass.”

One might ask what happens in a noisy, imperfect, acoustic environment? What does conversing with Pepper really add to a conveniently placed kiosk or tablet? How are Pepper’s emotional capabilities being used in this simple order-taking interaction? What happens if a customer strays from the dialogue the robot expects?

BOTTOM LINE

There’s no doubt that Pepper is an impressive engineering feat and that it is an advertising draw. However the emotion recognition aspects of Pepper didn’t appear to be important in both videos even though that is supposed to be Pepper’s strength. The entertainment value seemed to be what attracted the crowds. This temporary phenomena isn’t likely to persevere over time. In fact, this was shown to be true in China where restaurants began using rudimentary robots as mobile servers and busbots. In the last few months, however, there have been reports of those robots being retired because their entertainment value wore off and their inflexibility as real servers became evident.

The marketing around Pepper may have created expectations that can’t be met with this iteration of the robot. A comparison can be made here to Jibo and the problems it is having meeting deadlines and expectations. Jibo has extended the delivery date – once again – to October 2016 for crowdfunded orders, and early next year for the others.

The connection of Pepper to a telecom provider and the sales it brings in the form of 2 and 3 year data service contracts, can be big business to that provider: SoftBank is the exclusive provider of those data services in Japan. An example of the value of that business can be seen by a surge in share price of Taiwan telecom company Asia Pacific Telecom on news that the company will begin selling Pepper robots in Taiwan.

‘Robot kindergarten’ trains droids of the future

Less than 100 years from now, robots will be friendly, useful participants in our homes and workplaces, predicts UBC mechanical engineering professor and robotics expert Elizabeth Croft. We will be living in a world of Wall-Es and Rosies, walking-and-talking avatars, smart driverless cars and automated medical assistants.

But much work remains before robots will truly be integrated into our daily lives. In this short Q&A, Croft lays out the rules for engagement between humans and robots and explains why it’s crucial to get this aspect right.

What role will robots play in our lives in the future?

They will be everywhere, helping us at home and at work. They could make you breakfast in the morning and check on your kids. They could be your frontline staff, giving visitors directions and answering questions. They could be your physician’s assistant. Or you could have a robotic avatar that will attend a meeting for you while you’re traveling on the other side of the world.

Future robots may be self-replicating, self-growing, and self-organizing. The natural evolution of robotics is toward incorporating biology. We can now grow cells around bio-compatible structures; this opens the door for the combination of the biological systems with embedded artificial intelligence, and eventually the cyber-physical workforce of the future.

What technologies are driving the growth of robotics?

Computing power continues to grow exponentially, and ubiquitous communication is being made possible by wireless technology. Dense energy storage and new energy harvesting and conversion technologies allow machines to operate in the world, unplugged. And finally, machine learning: networked computer systems have global access to huge amounts of data that, combined with robotic embodiment, allow robots to learn about the world in ways that mimic and move beyond how people learn about their environment.

Your work at UBC focuses on human-robot interaction. Why is this important? 

As robots become more and more a part of our lives, the question becomes: what are the rules of the game? What is OK for robots to do, and what is not? Robots will have abilities that we don’t have, and we need to define what they are allowed to do with that capacity.

There are some big ethical questions to consider: how does society deal with drones that can kill, for example. But there are important day-to-day questions too. If a human and a robot are accessing the same resource – the same roadway, same tools, same power source, who yields? Does the person always get their way? What if the robot is doing something for the greater good, for example, a robotic ambulance?

In a way, I like to think of our lab as robot kindergarten. We are teaching robots basic, building-block behaviours and ground rules for how they interact with people: how to hand over a bottle of water, how to look for things, how to take turns. Having these basic behaviours in place allows us to create human-robot interactions that are natural and fluid.

To achieve our goals, our lab welcomes researchers from different disciplines—ethics, law, machine learning, experts in human computer interaction—as well as different international cultures. Different cultures have different ideas of robots. We learn a lot from these many perspectives.

Robots can help reduce 35% of work days lost to injury

What’s the biggest benefit for using collaborative robots? It’s not better efficiency. It’s not the extra hours the robot can work in a shift. It’s not even having improved consistency across your product. Whilst these are all great bonuses the biggest benefit of robots is their impact on reducing workplace injury.

Workplace injury is an issue that affects millions of workers worldwide, each year. It costs businesses billions in revenue. Although it’s not possible to avoid all injuries completely, many workplace injuries are avoidable. Musculoskeletal disorders are often preventable, as they are usually caused by bad workplace ergonomics. Collaborative robots are a great way to solve this problem.

In a previous article, we found how collaborative robots are designed to be ergonomic products in themselves. In this article, we’ll look at how collaborative robots can be used to reduce ergonomic problems across your workplace. We’ll also show how you can pick the best tasks for your collaborative robot by putting on your “ergonomics glasses.”

Musculoskeletal Disorders: Too important to ignore

Musculoskeletal disorders (or MSDs) refer to a set of injuries and disorders that affect the human body’s movement or musculoskeletal system, for example, the muscles, joints, tendons, nerves and ligaments. According to FitForWork Europe, MSDs are a huge problem in the modern world. 21.3% of disabilities worldwide are due to MSDs, and they are estimated to cost the European Union around 240 billion euros each year in lost productivity and absence, due to sickness. MSDs accounted for 35% of all work days lost in 2007 in Austria.

As they are caused by repetitive physical stresses on the human body some industries are more affected by it than others. Manufacturing and food processing are classed as high-risk, as outlined this report on the impact of MSDs in the USA. Some jobs are prone to specific injuries due to the type of work involved, such as industrial inspection and packaging jobs, which are prone to upper extremity MSDs. In 2012, the manufacturing industry had the fourth highest number of MSDs, with 37.4 incidents per 10,000 workers.

All this injury costs your business money; a lot of money. Ergo-Plus shows you would have to generate $8 million worth of extra sales to cover the cost associated with the most common MSDs. This is crazy, as the injuries are preventable by simply applying basic ergonomic principles.

How robots can reduce workplace injury

In 2013, we reported on a case study at Volkswagen, who had applied the UR5 collaborative robot to their facility. In it, JĂŒrgen HĂ€fner explained their reasons for introducing the robot:

“We would like to prevent long ­term burdens on our employees in all areas of our company with an ergonomic workplace layout. By using robots without guards, they can work hand ­in ­hand together with the robots. In this way, the robot becomes a production assistant in manufacture and as such can release staff from ergonomically unfavorable work.”

You can improve a task’s ergonomics in two ways:

  1. Use ergonomic principles to redesign the task, to reduce the physical stress on the worker.
  2. Find a way to complete the stressful part of the task differently, without using a human worker at all. This can hugely reduce the chance of MSDs.

The use of collaborative robots falls squarely into the second category. However, you still need to have a knowledge of ergonomic principles to know if a task can cause MSDs.

How to tell if a task can cause MSDs

Ergonomic professionals sometimes talk about having “ergonomics glasses” to mean viewing the workplace from an ergonomics perspective. Before you learned about ergonomics, you could have easily failed to notice that a task could injure a worker. After learning about them, ergonomics issues will jump out at you as you walk through your workplace. There are two different types of ergonomics:

  1. Proactive Ergonomics – This involves solving ergonomics issues before they arise, either by walking around your workplace whilst “wearing your ergonomics glasses” or by incorporating ergonomic principles into the initial design of processes.
  2. Reactive Ergonomics – This is what usually happens. It’s solving a problem when it is already a problem. A worker suffers an injury as a result of the task and so we retrospectively try to improve the ergonomics of the task.

At the very least, we should adopt a more proactive approach to ergonomics. In an ideal world, all ergonomics issues would be solved proactively, before they arise. However, being realistic, we’re likely to end up with a combination of the two approaches.

Three steps to improve ergonomics with collaborative robots

Applying ergonomics principles is really quite simple. It just involves a slight change of mindset and three easy steps.

Step 1: Learn what to look out for

The first step to proactive ergonomics is to learn how to spot bad ergonomics. There are some great resources online, particularly the free resources and blogs from Ergo-Plus, the International Labor Organization, Dan MacLeod and FitForWork Europe.

There are a few fundamental principles of ergonomics, which can vary slightly in wording depending on which resource you consult. Tasks which violate one or more of these will need to be redesigned or passed off to a robot, to avoid inflicting injury on the worker over time:

  1. Workers must maintain a neutral posture without putting their body in awkward positions.
  2. Reduce excessive forces and vibrations on the human body.
  3. Keep everything in easy reach and at the proper height, to allow the worker to operate in the natural power/comfort zones of the human body.
  4. Reduce excessive motions in the task. This is especially important in repeated motions.
  5. Minimize fatigue, static load and pressure points on the human body.
  6. Provide adequate clearance and lighting in the workplace.
  7. Allow the worker to move, exercise and stretch. After all, the human body is “designed to move” not stay in the same position for long periods of time.ergo-principles-4.jpg

Neutral and awkward back postures (source)

Become familiar with these principles by reading over the linked resources and looking at example images of good and bad ergonomic practices.

Step 2: Stand up and walk!

The second step is to stand up off your chair and walk around your workplace, noticing everything you can about the ergonomics of the tasks. Ask yourself (and then ask your colleagues) the following two questions:

  1. How could this task be improved to make it more comfortable (less physically stressful) to the worker?
  2. Which parts of the task could we give to a collaborative robot to solve the ergonomic issues?

We recommend that you take photos and videos of the tasks, to document the ergonomics improvement process. This will be useful in two ways, as you can then use the same photos to help you to design your collaborative robot process.

Step 3: Apply collaborative robots to improve ergonomics

Once you have identified problem areas in the workplace, you are likely to have a list of tasks which need improvement. Some of the tasks will be possible to carry out with a collaborative robot. Others will not, so you will need to improve their ergonomics in other ways.

Best practices for looking at tasks ergonomically

With so much information available about ergonomics, you might be thinking that you’d have to invest big in training to become a proactive ergonomics business. However, this is not necessarily the case. You can start small and still see big benefits. The International Labor Organization gives three simple things to remember when applying ergonomics to your workplace:

  1. It is most effective to examine tasks on a case-by-case basis. Ergonomics issues can be very specific to a task, so don’t think that doing exactly the same everywhere in the workplace will be effective. Start small, looking at just one or two tasks, and build up gradually.
  2. Even minor changes to ergonomics can drastically reduce injury. It might seem trivial to have a robot pick up a part and move it 50cm to be closer to a human operator, but after an 8 hour shift this simple movement can mount up to a huge physical strain on the worker. Simply knowing that the optimal working radius of a table is 25cm allows you to understand this and put it into practice.
  3. Staff should be involved in making any ergonomics changes to the workplace. People themselves are the best source of insight into how to improve their work tasks. Get your workers involved right from the start to identify problem areas and apply collaborative robots.

Why businesses must get ready for the era of robotic things

Internet_of_Things_Smart_phone_IoT_conveyor_Belt_industry_factory

We’ve entered a period of epic technological transformation that is impacting society in ways that are leaving even veteran tech observers speechless. In some ways, it might seem like 1998 all over again. The internet was then in its infancy and cyberspace was uncharted territory for much of the population. The Dot-com boom and eventual bust was inevitable and reflected the markets expanding and contracting with the newfound surge of interest, but obviously overinflated speculation, around the potential of the Internet to transform society. Following a tremendous growth spurt in the first 5-6 years, the World Wide Web ended its first decade by learning to become sociable.

Indeed, the rise of the digital social network through channels like Facebook, Twitter, Instagram, and Snapchat have transformed how businesses and individuals work, think, and communicate. And now that the Internet has crossed the threshold into young adulthood, it’s continuing to grow and drive massive transformations throughout all parts of business and society. Soon-to-be-released autonomous cars, wearable tech, drones, 3-D printing, smart machines, home automation, virtual assistants like Siri, you name it . . . the pace of change is staggering.

Many of the breakthroughs and innovations we’re seeing right now are a result of three major confluences over the past 8 years: mobile, cloud, and Big Data. These technologies have collectively resulted in quicker and more efficient means of collaboration, development, and production, which in turn have allowed businesses to achieve unprecedented levels of growth and expansion. New ways of working, often remotely, mean that more people can do their jobs outside of traditional corporate structures. We’ve entered not only the freelancer economy, but the startup one as well. Now everyone is an entrepreneur and innovation and new business growth is through the roof. What’s more is that technology processes and production cycles have become commoditized. This means that anyone with the right idea, system, skills, and network in place today can effectively build a billion dollar business with very low overhead costs.

This crazy rate of change is certainly great from the consumer standpoint, but also a bit unnerving for businesses simply trying to keep their head above the water. How are companies today to keep up with the market, their competitors, and with consumer expectations? What does all this change mean for startups struggling to gain traction, for more traditional brick and mortar businesses, and even for established enterprises that might be too big to pivot quickly?

These are more comprehensive questions that we’ll try to answer in another blog post. But for now, here is what we do know about the massive impacts over the next few years. The first thing is that Internet of Things is taking the world by storm with projections that 21 billion objects will be connected by the year 2020. That’s just about 3 for every man, woman, and child on the planet! A few years ago Cisco estimated that the IoT market would create $19 trillion of economic value in the next decade.

What’s more is that the global robotics industry is also undergoing a major transformation. Market intelligence firm Tractica released a report in November 2015 forecasting that global robotics will grow from $28.3 billion worldwide in 2015 to $151.7 billion by 2020. What’s especially significant is that this market share will encompass mostly non-industrial robots, including segments like consumer, enterprise, medical, military, UAVs, and autonomous vehicles. Tractica anticipates an increase in annual robots shipments from 8.8 million in 2015 to 61.4 million by 2020; in fact, by 2020 over half of this volume will come from consumer robots.

Putting together the two major industry trends, it doesn’t take rocket science to figure out that the two industries – Internet of Things and Robotics – will together lead to a “perfect storm” of global market disruption, opportunities, and growth in the next 4 years and beyond. This confluence is part of a larger epic transformation, which has appropriately been called the Second Machine Age. Listen to how this FastCompany article sums it up:

The fact is we’re now on the cusp of a “Second Machine Age,” one powered not by clanging factory equipment but by automation, artificial intelligence, and robotics. Self-driving cars are expected to be widespread in the coming decade. Already, automated checkout technology has replaced cashiers, and computerized check-in is the norm at airports. Just like the Industrial Revolution more than 200 years ago, the AI and robotics revolution is poised to touch virtually every aspect of our lives—from health and personal relations to government and, of course, the workplace.

This is a mouthful but in case it’s not clear, let me spell it out: there’s never been a better time than now to get onboard with robotics and Internet of Things!

If you’re a startup or small business owner, and especially feeling behind the technology curve, you’re certainly not alone. But instead of commiserating about all of the changes, proactively start today to ask yourself what it will take to get your organization to the next level of innovation. Set yourself up with a 6 month, 12 month, 18 month and 2 year innovation plan which maps to a broader 2020 strategy. Time is of the essence but it’s not too late to pivot and get onboard with the robotics and IoT revolution. As the famous statement goes, “The journal of a thousand miles starts with one step.”

Multi-robotic fabrication method has potential to build complex, stable, three-dimensional constructions

Multi-robotic fabrication methods can strongly increase the potential of robotic fabrication for architectural applications through the definition of cooperative assembly tasks. As such, the objective of this research is to investigate and develop methods and techniques for the multi-robotic assembly of discrete elements into geometrically complex space frame structures.

This endeavour implies the definition of an integrative digital design method that leads to fabrication and structure informed assemblies that can be automatically built up into custom configurations. The research is being conducted at Gramazio Kohler Research as part of the interdisciplinary research program of the Swiss National Centre of Competence in Research (NCCR) Digital Fabrication. It started in September 2014 by Stefana Parascho and currently includes collaborations with Augusto GandĂ­a and Thomas Kohlhammer.

Spatial Structures

Space frames structures developed during the industrial revolution as efficient systems for large-span constructions, but quickly reached a limitation of their variability through the necessity of standardisation as well as complex connection detailing. Through the development of a multi-robotic assembly method as well as an integrated joining system, irregular space frame geometries become buildable, enhancing existing typologies through their potential for variability and efficient material use. The use of robotic fabrication techniques and the avoidance of pre-fabricated, rigid connections lead to a system that relies not only on digital planning and manufacturing but includes digital assembly as an addition to the digital chain. A process of robotic build-up of triangulated structures was developed, based on the alternating placement of rods. This way, one robot always serves as a support for the already built structure while the other assembles a new element (Figure 02). As a result, the built structures do not require any additional support structures and are constantly stabilised by the robots.

Integrative Design Methods

Traditional architectural design methods commonly follow a top-down strategy in which both construction and fabrication are subordinated to a previously predefined geometry. In an integrative design approach, the fabrication, structural performance and given boundary constraints can simultaneously function as design drivers, allowing for a much higher flexibility and performance of the system. As such, the presented research focuses on the development of a design strategy in which various factors, such as constraints and characteristics of the multi-robotic fabrication process, are included in the geometric definition process of the structures.

Multi-robotic fabrication

The use of multiple robots for the assembly of discrete element structures opens up potentials for the build-up of complex, stable, three-dimensional constructions. At the same time, the process introduces various challenges such as the necessity for collision avoidance strategies between multiple robots and respective robotic path planning. In order to generate buildable structures, the design process needs to integrate the robots’ constraints, such as robot reach and kinematic behaviour, and at the same time process data from robotic simulation in order to foresee the robots’ precise movements. Through the collaboration with Augusto Gandía from Gramazio Kohler Research a strategy for implementing robotic simulation into a CAD environment and for generating collision free trajectories for multi-robotic applications was developed.
