At this stage of its development, PETMAN is here to assist mankind. However, it's clearly fated to be weaponized as an AT-ST walker in support of Imperial ground forces. For the time being anyway, this biped humanoid is being built by Boston Dynamics to test military suits used to protect soldiers in chemical warfare. As an evolutionary advance from its four-legged BigDog platform, PETMAN does the ol' heel-toe at a healthy 3.2 MPH (5.14 KPH) and packs enough balancing intelligence to remain upright even when given a shove from the side. Check out the action after the break.
