Carlos found this little safe in the trash. It’s got stuff locked away inside. He wants in, but doesn’t want to destroy the safe. So he created a Pololu Micro Serial Servo Controller-powered, servo-controlled, robot safe-cracker, house in an old PC power supply.
The results? So far: safe: 1, bot-cracker: 0. Turns out, the servo motor and gearing was not precise enough to turn the dial reliably. Carlos is going to try a stepper motor next. He decided to post the project failure so that others would have the benefit of his mistakes.
