Miniature Rotary Electrostatic Clutch Insect-scale crawling robots can traverse confined environments; nevertheless, their functionalities are mostly limited due to challenges in integrating actuated degrees of freedom. In the Research Article (DOI: 10.1002/aisy.202500625), Kyu-Jin Cho and co-workers present a miniature rotary electrostatic clutch that incorporates cutting patterns into the clutch layer. The clutches are inserted at several joints to create a small robot with six independently actuated joints for manipulation and reconfiguration.
