This spinning-mass principle drives several robots in development. One is a remote-controlled wheel that jumps when the internal mass rotates fast enough to lift it off the ground. Unlike spring-based ...

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) ...

Shape-morphing, insect-scale robots that feature an origami-inspired design and eight independently actuated degrees of freedom, powered by custom piezoelectric actuators for enhanced mechanical ...

By studying the American grasshopper’s unique folding wings, researchers created 3D-printed models to test various aerodynamic features.

Grasshoppers may not spring to mind as paragons of graceful flight. But for a team of Princeton engineers, these gangly insects have inspired a new approach to robotic wings. Typical designs for ...
