High-Speed, Maneuverable, and Terrain-Adaptive Micro-Robot with Tree Frog-Inspired Bionic Feet. [PDF]
A 7.5 mm micro‐robot integrates tree frog‐inspired bionic feet with an electromagnetic linear motor to achieve high‐speed locomotion, slope climbing, and precise turning. It reaches 39 body lengths per second and ascends 30° slopes. The system demonstrates strong potential for inspection tasks in confined and complex environments, such as micro‐aero ...
