Bioinspired Adaptive Leg-Claw Enables Robust Perching and Grasping for UAVs. [PDF]

Adv Sci (Weinh)
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...
