A ketchup bottle cap inspired Princeton engineers to build a shape-shifting robot that moves without a motor
- The hinge on a typical flip-top ketchup cap attaches a thin, flexible shell to a thicker, rigid base along a curved edge, creating 2 distinct stable positions separated by an energy barrier that the cap must overcome to switch between them.
- That simple piece of everyday plastic engineering helped reveal s
