Soft-bodied origami robot moves without motors or gears

"Ancient Japanese Art Brings Spineless Robot To Life!" Sounds very much like a movie plot summary. In reality, it perfectly describes the work of Princeton University engineers who have created a robot that moves without a single motor or gear, using heat and the principles of origami instead. Their soft robotic system relies on a combination of heat-sensitive advanced materials, flexible embedded electronics, and carefully designed folding structures to produce motion, ditching traditional mech...
