This humanoid Atlas robot can take a punch

You might call this the Energizer Bunny of the robot world. The newest version of the Boston Dynamic's Atlas robot just keeps going, even when one his handlers thrust a hockey stick into its chest and then knocks it down from behind. It also holds its own outdoors, taking a stroll through a snow-covered forest and righting itself after nearly falling down.

In a video of its exploits posted online by the company, the robot also can be seen opening a door and heading outside. It also isn't a bad warehouse worker, lifting and place boxes on a shelf and picking up one on the floor - even after its handler repeatedly moves it beyond its reach.

Perhaps the moment that is most troubling -- and maybe reminiscent of something out of "The Terminator" -- is when it's knocked down and manages to get back up. Mobile users click here to watch
