Elastic robot jumps endlessly powered by infrared light

Original: Wind-up elastic robot jumps forever when fed infrared light

Researchers have developed a wind-up elastic robot that can keep jumping continuously when supplied with infrared light. The material converts the light into heat, re-tensioning its elastic body so the hopping cycle repeats without batteries or manual rewinding. The demonstration is drawing attention as a possible route to small, untethered soft robots for exploration or search tasks.

Why now: A battery-free robot powered only by light is a striking advance in soft robotics that sparks curiosity about future applications.
