Roboticists are envisioning a future in which soft, animal-inspired robots can be safely deployed in difficult-to-access environments, such as inside the human body or in spaces that are too dangerous for humans to work, in which rigid robots cannot currently be used. Centimeter-sized soft robots have been created, but thus far it has not been possible to fabricate multifunctional flexible robots that can move and operate at smaller size scales.
The deep ocean – dark, cold, under high pressure, and airless – is notoriously inhospitable to humans, yet it teems with organisms that manage to thrive in its harsh environment. Studying those creatures requires specialized equipment mounted on remotely operated vehicles (ROVs) that can withstand those conditions in order to collect samples. This equipment, designed primarily for the underwater oil and mining industries, is clunky, expensive, and difficult to maneuver with the kind of control needed for interacting with delicate sea life. Picking a delicate sea slug off the ocean floor with these tools is akin to trying to pluck a grape using pruning shears.

In the last few years, deep learning practitioners have proposed a litany of different sequence models. Although recurrent neural networks were once the tool of choice, now models like the autoregressive Wavenet or the Transformer are replacing RNNs on a diverse set of tasks. In this post, we explore the trade-offs between recurrent and feed-forward models.
In this episode, Marwa ElDiwiny interview Peer Fisher, a Professor of Physical Chemistry at the University of Stuttgart and the Director of the Micro Nano and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems. Fischer discusses micro robots that has been designed to move inside of environments similar to the human body called, “micro swimmers.” He talks about how they are fabricated, powered, and how they can move with light or “nano propellers.” Fischer also discusses simulating human tissue and the future of micro and nano robots, including how they could be a replacement for certain surgeries.
A few weeks ago we had the kick-off meeting, in York, of our new 4 year EPSRC funded project Autonomous Robot Evolution (ARE): cradle to grave. We – Andy Tyrrell and Jon Timmis (York), Emma Hart (Edinburgh Napier), Gusti Eiben (Free University of Amsterdam) and myself – are all super excited. We’ve been trying to win support for this project for five years or so, and only now succeeded. This is a project that we’ve been thinking, and writing about, for a long time – so to have the opportunity to try out our ideas for real is wonderful.
Robots become every day more ‘intelligent’. What if robots were intelligent enough to say NO to war? This would be a happier future.
This short film is a light-hearted comedy that aims to launch an interesting discussion and motivate reflexion on the killer-robots topic. The fictional scenario describes a future where robots contract out and refuse to be employed in human warfare. This optimistic point of view can be inspirational to engineers and roboticists developing a robotic future.
For a lot of people, being a passenger in a car can easily lead to motion sickness, particularly if they try to do something like looking down to read a book or stare at a phone. Not everybody gets this, but it’s enough to be a big issue for the robocar world. Drivers usually don’t feel this much, but in the robocar world, everybody’s a passenger.
In nature, cockroaches can survive underwater for up to 30 minutes. Now, a robotic cockroach can do even better. Harvard’s Ambulatory Microrobot, known as HAMR, can walk on land, swim on the surface of water, and walk underwater for as long as necessary, opening up new environments for this little bot to explore.
The open ocean is the largest and least explored environment on Earth, estimated to hold up to a million species that have yet to be described. However, many of those organisms are soft-bodied – like jellyfish, squid, and octopuses – and are difficult to capture for study with existing underwater tools, which all too frequently damage or destroy them. Now, a new device developed by researchers at Harvard University’s Wyss Institute, John A. Paulson School of Engineering and Applied Sciences (SEAS), and Radcliffe Institute for Advanced Study safely traps delicate sea creatures inside a folding polyhedral enclosure and lets them go without harm using a novel, origami-inspired design. The research is reported in Science Robotics.
