Petman the robot can do push-ups, looks like a human

Beware, humans, there is a robot living in the United States that could threaten our very existence.

Well, at least, it can out-walk you on a treadmill and test the heck out of safety equipment. The company Boston Dynamics uploaded last week a video of its robot designed to test safety clothing, named Petman, and it's already been viewed more than a million times, with the obligatory comments declaring its realistic human movements the beginning of the robot uprising.

In this video, Petman tests a gas mask and clothing designed for protection against chemicals, according to the description. It says the robot's 'skin' has sensors to detect if any chemicals bleed through the clothing. Petman walks, bends its knees and twists its torso to simulate movement. Petman also sweats.

In an earlier video of the robot, uploaded to the Boston Dynamics website, Petman does push-ups and lifts its arms. A staff member pushes the robot and it steps sideways from the force but doesn't lose balance.

The company wrote that Petman was funded by the U.S. Department of Defense's Chemical and Biological Defense Program. The robot tests protective clothing for potential chemical and biological weapons.

Perhaps most interesting, however, is that when it's dressed up in protective gear, Petman could easily be mistaken for a human walking along, arms at his sides.

We'll refrain from worrying until someone hears Petman start to speak.

Especially if he's saying, "I'll be back."
