A simple idea has led to a surprising invention: tiny robots made from knotted fibers that can jump, spin, glide and even ...

Scientists turned simple knots into tiny robots that jump, spin, and plant seeds, offering a new tool for ecosystem restoration.

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 ...

However, if the elasticity and material are carefully selected, the knot itself becomes an active system, explains Shu Ya ...

(Nanowerk News) Researchers have made a significant leap forward in developing insect-sized jumping robots capable of performing tasks in the small spaces often found in mechanical, agricultural and ...

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 ...

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) ...
