Cracking combination locks has never been so easy. A group of engineering students at Olin College of Engineering have built a robot that will solve any MasterLock combination in a under two hours by running through all the possible combinations. Just set it and forget it.
The hardware system is pretty simple: a clamp that holds the lock in place, a stepper motor that spins the combination, and a solenoid grabber that continuously pulls on the lock to see if it’s open. What’s more impressive is the LockCracker software the team built. Put the lock--that is, YOUR lock--in place, launch the software, and walk away. The software runs until the combination is solved; your left with an unlocked combo lock and the combination displayed on the screen.
