NewzResearchers led by Yue Gao have developed a small walking robot capable of moving for 150 days without relying on any conventional battery. The key innovation is a specialized membrane installed in the robot's legs that generates electricity every time it makes contact with a metallic surface, effectively using the ground itself as an energy source.
This development marks a significant advancement in autonomous robotics by demonstrating a method for continuous locomotion without internal power storage. By harvesting energy directly from surface interactions, the technology opens new possibilities for long-term deployment of small robotic devices.
