Choosing the right cable to use in any application depends on many parameters. One of the most important is its ability to thermally resist a maximum imposed current.

We introduce Flamingo, a single visual language model (VLM) that sets a new state of the art in few-shot learning on a wide range of open-ended multimodal tasks.

We caught up with Kevin Millikin, a software engineer on the DevTools team. He’s in Salt Lake City this week to present at PyCon US, the largest annual gathering for those using and developing the open-source Python programming language.

A mechanical jumper developed by UC Santa Barbara engineering professor Elliot Hawkes and collaborators is capable of achieving the tallest height—roughly 100 feet (30 meters)—of any jumper to date, engineered or biological. The feat represents a fresh approach to the design of jumping devices and advances the understanding of jumping as a form of locomotion.

A research team from Chemnitz and Dresden has taken a major step forward in the development of sensitive electronic skin (e-skin) with integrated artificial hairs. E-skins are flexible electronic systems that try to mimic the sensitivity of their natural human skin counterparts. Applications range from skin replacement and medical sensors on the body to artificial skin for humanoid robots and androids. Tiny surface hairs can perceive and anticipate the slightest tactile sensation on human skin and even recognize the direction of touch. Modern electronic skin systems lack this capability and cannot gather this critical information about their vicinity.

Dear robotics graduate students and newcomers to robotics,

If you are what I imagine delving into robotics to be like today, the majority of your time is spent as follows:

• navigating Slack channels while tuning into some online lectures,
• trying to figure out whether you should be reading more papers, coding more, or if you are just a slow reader/coder/etc,
• and if you are a grad student, in particular, having a never-ending cycle of self-doubt questions that seem super important, such as “what is a research question anyway? And how do you find one that no one has tackled before — and not because it’s a dumb question? Oh wait… is my question dumb? Can I find out without asking my prof?”

Much of the questions I had as a grad student stemmed from my lack of knowledge about what is considered to be normal by academia, the robotics community, and more narrowly the subdomain of robotics I belonged to. The friends/colleagues/people I met along the way helped me fill that much-needed knowledge gap about the norm because many of us were on the same journey with similar struggles/questions.

As an assistant professor who spent the majority of my professorship in the COVID-19 pandemic mode, I worry that my students’ grad school journey has not offered the same kind of shared experience and camaraderie with people in the domain that I am now seeing the huge benefit of.

The upcoming IEEE International Conference on Robotics and Automation 2022 will be the first robotics conference that many of you attend in-person since the pandemic (I’m in this category). For many of you, it may be your first time attending an academic conference. For even more of you, this may be your first virtual attendance at ICRA.

ICRA is a multi-track, full-week of robotics festivity that draws in thousands. It can pass by you in a blink.

So, in a series of short blog posts (because, who has the time these days), I am going to highlight a few things in the form of a millennial’s guide to ICRA.

I’m assuming that you, the reader, may be as impatient a reader as I am, who likes information presented in a short, snappy, and organized way. The more bullet points the better.

So let’s get started.

** Full disclosure, I’m one of the two publicity co-chairs for the ICRA conference. If you want to be on the grounds of ICRA as a student science communicator, reach out to us. **

Robots were first introduced to manufacturing assembly lines in 1978. Since then, the hardware (mechanics and control systems) has improved significantly. Yet the way these robots are programmed has not changed very much.

A research group from Robotics Institute of Beihang University, China has developed a novel multifunctional hexapod robot with leg-arm integration, named ALLOMAN (Arm-Leg Locomotion and Manipulation). This robot possesses various "fixed" manipulation functions besides locomotion, and the researchers have achieved mobile manipulation function on this robot successfully, which is difficult for legged robots. Their study can be found in the journal Frontiers of Mechanical Engineering on 8 April, 2022.

In April 2022, the project "Smart Electronic Olfaction for Body Odor Diagnostics"—SMELLODI for short—started with the kick-off meeting. The objective of the seven partners from Germany, Israel and Finland is to develop intelligent electronic sensor systems that can distinguish between healthy body odors and those altered by disease and transmit them digitally. Over a period of three years and with funding of almost 3 million euros, the technology developed is to pave the way for the digitization of the sense of smell.

A robot named Lyra has been used to inspect a ventilation duct in Dounreay's redundant nuclear laboratories and map radioactive materials. Lyra traversed 140m of duct from a single entry point and provided operators with detailed radiological characterization information that can now be used to help plan safe and efficient decommissioning of the laboratories.

Researchers at the Max Planck Institute for Intelligent Systems (MPI-IS), Cornell University and Shanghai Jiao Tong University have developed collectives of microrobots which can move in any desired formation. The miniature particles are capable of reconfiguring their swarm behavior quickly and robustly. Floating on the surface of water, the versatile microrobotic disks can go round in circles, dance the boogie, bunch up into a clump, spread out like gas or form a straight line like beads on a string.

For decades, researchers worldwide have been trying to develop robots that can efficiently assist humans and work alongside them as they tackle a variety of everyday tasks. To do this effectively, however, the robots should be able to interact naturally with humans, including handing them and receiving objects from them.

Harmonic Bionics has developed a patented robotic actuator, which uses a load cell that is mechanically isolated from any extraneous loads. The result is that each load cell can sense the force exerted by only the joint of the robot it is mounted to.

With e-commerce orders pouring in, a warehouse robot picks mugs off a shelf and places them into boxes for shipping. Everything is humming along, until the warehouse processes a change and the robot must now grasp taller, narrower mugs that are stored upside down.

By working with robots, employees can gain valuable technical skills and perform their jobs more efficiently. There are varying levels of collaboration that businesses can implement and strategies they can use to make sure collaborative robots are safe.
