Walking vehicle

A walking vehicle is a vehicle that moves on legs rather than wheels or tracks. Walking vehicles have been constructed with anywhere from one to more than eight legs. There are many designs for the leg mechanisms of walking machines that provide foot trajectories with different properties.

Walking vehicles are classified according to the number of legs with common configurations being one leg (pogo stick or "hopper"), two legs (biped), four legs (quadruped), and six legs (hexapod). There are a few prototypes of walking vehicles. Currently almost all of these are experimental or proof of concept.
