When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked ...

To create a robot that could jump high and land stably, the researchers recognized that they needed to strike a balance between both goals. They represented both jumping height and landing success ...

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

Using a dual-material fiber that consists of a stiff Kevlar core and a surrounding shell of liquid crystal elastomer (LCE), ...

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

A knot doesn't just fall apart, it snaps. Engineers harnessed that energy release to create tiny soft robots that leap meters high, flip, spin or glide. (Nanowerk News) When a knot lets go, it doesn’t ...
