IHMC Planar Elliptical Runner
The most elegant solution is often the simplest. Making robots walk requires lots of hardware — in the form of motors, servos, gyroscopes, and the structure of the robot itself — and software to process those data points and translate them into movement. The Planar Elliptical Runner is a prototype bipedal robot that uses mechanical design to ditch much of the hardware and all of the software required to make it move, using only a motor and remote control.
