A new Google robot is running around in the woods of eastern Massachusetts, and this time there's no power cord preventing it from going anywhere it pleases.

In a video posted to YouTube yesterday (below), Google subsidiary Boston Dynamics unveiled the latest addition to its lineup of humanoid robots. The video is cleverly edited to evoke a science fiction film—part E.T., part robot horror movie. It starts with the robot opening the door to the Boston Dynamics headquarters in Waltham, Mass., crossing the parking lot, and entering the snow-covered woods.

After returning to the factory, a bearded employee gives the robot the task of picking up a 10-pound box, which it does with no problem. But then the employee cruely strikes the box from the robot's circular hands. It's not fazed, and walks right back over to the box and picks it up again.

As if that wasn't enough to prove the robot's resiliency, the employee then hits it from behind with a cardboard tube so hard that it falls over. Eventually, the robot rights itself, and the video ends with it walking out the factory door. Will it seek revenge on an unsuspecting human?

The robot's body is very similar to the rest of the Atlas lineup of humanoid robots, which Boston Dynamics has been working on for years. But the lack of a power cord sets this one apart. In an August 2015 video, the company's founder Marc Raibert explained that untethering it was a priority.

In addition to being a Google subsidiary, Boston Dynamics also designs robots for the U.S. military under a DARPA grant.
