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 ...

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

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 ...

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 ...
