Meet Spot the robot dog. Now watch a man kick it really hard.
In the video, Spot, a four-legged robot about the size of a St. Bernard, gets kicked by a man as it trots down the hallway of a building and barely breaks its stride. Shortly after, it withstands a much bigger kick in a parking lot, causing it to slip on the asphalt and back away as it regains its footing.
In an uncannily canine motion, it almost looks as if it's cringing from the blow.
But the 73-kilogram robot doesn't fall down and appears no worse for wear in subsequent scenes.
"No robots were harmed in the making of this video," Boston Dynamics assures us at the end of the video.
Later scenes show the robot loping through the woods, jogging alongside a human runner, and climbing up and down hills. As the robot moves, the electrically powered, hydraulic actuators that move its legs make a constant squealing whirring noise.
According to Boston Dynamics, the robot's sensor head helps it navigate and negotiate rough terrain. The head, which looks more like a hump on its shoulder, features a spinning cylinder with a spot on it.
Boston Dynamics didn't say what the robot was for, but it is similar to a heavier four-legged robot called LS3 designed for military use. LS3 is designed to accompany soldiers on foot through rough terrain and help carry their load — up to 180 kilograms (400 pounds) of gear per robot.
Google bought Boston Dynamics, a maker of futuristic, military-grade robots, in December 2013.
