Brute Force Safecracking

If you wanted to get into a safe, but didn't know the combination, how would you crack it? The dumbest, but guarenteed to work, solution is to try every combination until one works. A human safecracker would get tired within a few hours of doing this, so Hack A Day reports someone automating this...with robots. The robot works faster than a human safecracker too.
The robot is a metal-and-plastic manipulator machine controlled by an embedded computer, and would fit in a backpack. If the thief is sneaky, and does this at a time when most people are asleep, and muffles the whirring noise made by the servos, he could sneak it into a bank at 2am in a backpack, muffle all noise in the area, let it grind away for 3 hours, grab the safe contents, grab the machine, and be gone by 6am. If he's stealthy enough, no one would even notice.
In some ways, I suppose this was inevitable. Cryptographic brute force is the only known way to solve NP based problems, and the only P based way to crack a safe would be to somehow figure out some pattern to the combination based on the manufacturer's serial number.

Except in our fraudulent banking systems the bank vaults contain nothing! Fort Knox, unaudited since WWI. COMEX regularly has to settle cash for silver and gold contracts too.
