It can navigate through rugged, muddy and snowy terrain and keep itself from getting into a jam. It can also take some external blows without losing it’s balance.

The 4 legged robot has an on-board computer that controls it’s movement through servo motors and sensors to maintain direction, balance and make decisions about moving through it’s terrain. It even can absorb energy back from steps to make …
