• Last week, we reported on now Walmart is testing the use of robots to scan aisles and shelves for out of stocks.

Now, Walmart has a video online that shows exactly how it works. And you can watch it at right.

KC's View: When you’re watching the video, when it gets to the point where the Walmart employees gather around the robot with (pained) smiles on their faces, try freezing the frame.

Looks like a hostage video to me.
