This soft robot jumps under infrared light without needing a reset

The design stores torsional energy and releases it in repeated leaps, while small weight changes and light intensity alter distance and direction.

Researchers at North Carolina State University have developed soft robots that can repeatedly jump when exposed to infrared light. The teardrop-shaped devices can leap upward or move forward, continuing to jump for as long as the light remains on. Unlike conventional jumping robots, the new design does not require an external mechanism to reset after each jump, allowing it to repeat the motion autonomously. The researchers say the work could ena…
