High‐Speed, Maneuverable, and Terrain‐Adaptive Micro‐Robot with Tree Frog‐Inspired Bionic Feet
Advanced Science, EarlyView.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 ...

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...
