Terrifying. The sound of MABEL's hard metal feet on the lab floor sends a chill down my spine. These poor, blind researchers at University of Michigan don't know what havoc they've wrought on our future. Who will save us?

Well, ok. MABEL can only run at a top speed of 7mph. Hardly Usain Bolt speed. Still, when our robot overlords come, I'll think of MABEL and the cold clank of her test run. Thanks a lot, DARPA. This is where it starts. Or is it happening already? [YouTube]
