NASA's Spidernaut robot arachnid

We've heard tell of NASA's Spidernaut, a large robot designed to service spacecraft, but after finally seeing it in action we're not so sure humans are fully prepared to battle against robots in the coming rebellion -- this thing is pretty hardcore. Supposedly its current incarnation is only 1/4 of the final size, but the target is a 600 pound robot that can distribute weight evenly over its eight legs to avoid damaging the skin of the spacecraft or for scurrying across solar panels. NASA is even looking into a "web" deployment system for the bot, in which case we're hiding the women and children and locking the doors.
