Wind-up elastic robot jumps forever when fed infrared light
Wind-up elastic robot jumps forever when fed infrared light
Researchers from North Carolina State University have developed a soft, non-electronic robot that jumps continuously using infrared light. The 'soft ring jumper' uses elastic energy stored through torsion, with a V-shaped aluminum stopper controlling the direction of movement. By adjusting the geometry of the V-stop, the robot can crawl, jump forward, or leap vertically. The design enables autonomous jumping without external resets, opening possibilities for use in environmental navigation and unstructured terrain.

The study introduces a soft, non-electronic robot that uses infrared light to power continuous jumping through elastic energy storage and release. The robot's movement is controlled by geometric parameters, and its design enables autonomous jumping without external resets. This represents a fundamental advance in soft robotics for applications like environmental navigation and unstructured terrain
