Supplementary movie S5 from An insect-inspired collapsible wing hinge dampens collision-induced body rotation rates in a microrobot

Overhead view of a flexible wing collision that occurs relatively late in the wing stroke, recorded at 11,000 frames/sec. The obstacle on the left side of the screen is moved up into the wing path, causing the wingtip to collide. Flexible wing collisions generally yielded lower airframe yaw rates than those resulting from stiff wing collisions because the flexible wing tip absorbed some of the impact force.
