Introducing Spot
Leave a comment »
Powered by an electric motor that keeps a series of hydraulic actuators moving, Spot also features built-in sensors allowing it to automatically navigate difficult terrain. And because Spot is significantly smaller and lighter than Big Dog, it’s able to jog along at an impressive pace. It doesn’t look like it would be able to carry as much gear and equipment as Big Dog, which is why the quadruped was originally built. But that’s probably because Boston Dynamics has built it for different purposes, like search and rescue or scouting, instead of just back-breaking labor.
