Battery-free robot jumps using only light power

A miniature robot that operates without batteries, motors, or any electronic components has demonstrated the ability to jump repeatedly when exposed to light. The secret lies in its unique rubber-like material, which changes shape under light, accumulates energy, and then suddenly releases it.

This insect-sized, light-powered jumping robot is not science fiction; it is a reality in the lab. The soft machine propels itself into the air, with its movement intelligently controlled not by a system, but by the cleverly designed material itself.

This form of mechanical intelligence raises questions about the future of robotics. Such light-powered devices could potentially be deployed in environments like forest fire monitoring or disaster areas, offering a novel approach to remote operation.

The robot's ability to perform 188 consecutive jumps without interruption after activation is particularly remarkable, showcasing the efficiency of its energy storage and release mechanism powered solely by light.
