Active Matter, Curved Spaces: Mini Robots Learn to ‘Swim’ on Stretchy Surfaces

Physicists are using small wheeled robots to better understand indirect mechanical interactions, how they play a role in active matter, and how we can control them. Their findings, “Robotic swimming in curved space via geometric phase” are recently published in the The Proceedings of the National Academy of Sciences (PNAS).

The physics of walking is simpler than we thought

The physics of walking for multi-legged animals and robots is simpler than previously thought. That is the finding described by a team of roboticists, physicists and biologists in the Sept. 5 issue of the Proceedings of the National Academy of Sciences, in a paper titled “Walking is like slithering: a unifying, data-driven view of locomotion.”

This ‘squidbot’ jets around and takes pics of coral and fish

Engineers at the University of California San Diego have built a squid-like robot that can swim untethered, propelling itself by generating jets of water. The robot carries its own power source inside its body. It can also carry a sensor, such as a camera, for underwater exploration. The researchers detail their work in a recent issue of Bioinspiration and Biomimetics.

These flexible feet help robots walk faster

Roboticists at the University of California San Diego have developed flexible feet that can help robots walk up to 40 percent faster on uneven terrain such as pebbles and wood chips. The work has applications for search-and-rescue missions as well as space exploration.

Sticky business

Kaichang Li has spent his career crafting environmentally friendly adhesives. His first product, an adhesive made from soy flour and magnesium oxide, is utilized extensively throughout the hardwood-plywood industry. Now, Li’s lab has developed a vegetable-based pressure-sensitive adhesive with avast array of applications in multiple industries.
