The Crabster CR200 is a 1,400-pound behemoth of a 'bot soon being sent to the ocean floor—for both scientific and commercial use. Up until now, we've mostly seen it in action through still photos and animations, but here it is, menacingly lumbering into video. 

 

The machine you see here isn't complete; it's without the outer shell the Korea Institute of Ocean Science and Technology team will be adding. But earlier this year the goal was to begin full-depth (656 feet) testing in spring, and it looks like they'll make that deadline, far too late to make a convincing version of Wild Wild West.
