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

Small flying robots face a persistent tradeoff between endurance and complexity. Flapping-wing designs can generate thrust ...

Tiny flying robots have always faced a brutal trade-off between agility and battery life, burning through power just to stay aloft. A new wing architecture inspired by grasshoppers promises to ease ...

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 ...
