1. Force and angular speed profiles in the normal collision (contact angle, 90°) at 1.2 m/s for the naked and origami-protected configurations on the rough and smooth surfaces.
Force and angular speed profiles in the normal collision (contact angle, 90°) at 1.2 m/s for the naked and origami-protected configurations on the rough and smooth surfaces. The design configuration and collision conditions related to each impact scenario are illustrated by icons above each graph. The shaded areas represent the range of data (from five trials) corresponding to each collision. (A) Rough surface with fixed protector. (B) Rough surface with rotary protector. (C) Smooth surface with fixed protector. (D) Smooth surface with rotary protector.
