Google's incredibly scary robo-dog was enjoying its walk outdoors in September, where the Skynet-infused robot dog was training with the Marines.
Boston Dynamics, which Google acquired in December 2013, had the Marines testing Spot's abilities of traversing rougher terrains like hills, woodlands, and cities while they controlled it from 500 meters (0.31 miles) away on a laptop with a game controller. They said it was so easy to control that a four-year-old could do it, which should scare us all.
During the test, the Marines were able to teach the robot dog to peek around corners to spot enemies - a nice trick for a robot dog. Spot also weighs a hefty 160 pounds (72.5kg).
