Soft biohybrid morphing wings with feathers underactuated by wrist and finger motion

Science Robotics, 2020
A soft biohybrid aerial robot with underactuated feathers shows how birds can steer by morphing their wings with wrists and fingers. Since the Wright Flyer, engineers have strived to develop flying machines with morphing wings that can control flight as ...
