When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot ...

Researchers at Penn Engineering have turned a common nuisance—a knotted string—into a high-performance, heat-activated ...

A 301 mg soft robot jumps continuously under constant light without batteries or electronics, using snap-through buckling and self-shadowing to create an autonomous feedback loop. (Nanowerk Spotlight) ...

In a test of 60 jumps, the robot made a perfectly controlled landing 52 times, sat back on its "heel" five times, and fell over just three. Controlling the landing has hugely boosted Salto's jumping ...

Last year at the Humanoid Robot Half-Marathon in Beijing the winning robot stumbled across the finish line in 2 hours and 40 ...

Engineers have created a tiny robot weighing less than a tennis ball that can jump an astonishing 31 meters into the air. Using a clever spring-loaded design, the robot stores energy over time and ...
