Biomimetic Wing (IMAGE) IOP Publishing Caption Graduate student Amanda Stowers of The Lentink Lab at Stanford University demonstrates her passive morning wing design for a flapping robot. The wrist hinge enables the robot to comply with hard impact of a steel rod, while the flapping motion forces the wings to fully extend again after impact.
