People of Earth, meet your new robotic overlord: Cujo AKA the Legged Squat Support System (LS3).

Cujo has been demoed before, but the US Military recently showed off  the latest iteration of its fancy new mechanical assistant, used to carry cargo, but it could totally become a trampling death-machine in seconds.

“I was surprised how well it works,” said Lance Cpl. Brandon Dieckmann. “I thought it was going to be stumbling around and lose its footing, but it’s actually proven to be pretty reliable and pretty rugged. It has a bit of a problem negotiating obliques and contours of hills.”

Cujo can traverse rocky terrain with its lifelike gallup, and is programmed to follow an operator and detect surrounding objects with its swiveling head of sensors. Marines demonstrated Cujo’s tricks by using it to conduct resupply missions across terrain difficult to traverse by normal vehicles.
