What's so unnerving is the way that it runs, completely non-plussed by the rough terrain and even leaping over any obstacles that get in its way.
The team set their robot dog SpotMini with the task of following a route around the building.
To successfully navigate the campus, Boston Dynamics said the SpotMini had to be "manually driven" through the office spaces, so that it's onboard computer could build a virtual map of the area. It's unclear who will be able to buy them and for how much.
The SpotMini now comes with a terrifying appendage, one so incredibly versatile that the feared robot apocalypse now seems more "when" than "if".
Although Boston Dynamics never released a commercial robot under Google, Raibert credited his company's former owner for helping it to start thinking of ways to bring its technology to a broader market.
The four-legged robot extends its mechanical arm, turns the door handle and opens it, letting both robots through. It can operate for about 90 minutes on a charge. While there's no word yet on price, the company has said that the SpotMini prototype was 10 times less expensive than its older sibling. "We're also looking at construction".
The most recent SpotMini design appears to incorporate sensors on the front and sides of its main body that help it understand its environment.
Boston Dynamics has been developing a range of robots, each with their own skills.
