New 3D-printed robot uses wind not batteries to explore harsh terrains

Researchers at Cranfield University have developed WANDER-bot, a low-cost, fully 3D-printed robot that uses wind power instead of batteries to navigate harsh environments such as deserts, polar ice caps, and potentially other planets. The robot’s design combines a Savonius wind turbine with the Jansen linkage mechanism, enabling mechanical leg movement driven entirely by wind energy. This approach eliminates the battery drain typically associated with robotic locomotion, allowing onboard electronics like cameras and sensors to operate on smaller power sources. The modular, simple design facilitates on-site repairs and part replacements through 3D printing, making it suitable for remote or extraterrestrial missions where resupply and maintenance are challenging. WANDER-bot’s print-as-you-go philosophy addresses the limitations of current space exploration hardware, which is often complex and difficult to fix remotely. By enabling astronauts or remote stations to manufacture replacement parts as needed, the robot could reduce reliance on costly and lengthy resupply missions. Although still at an early technology
