Picking a lock typically requires a special tool and a tension wrench, but this lock picking robot utilizes tough rigid wires passing through tiny holes in a blade shaped to fit in the keyway.
These wires basically push all the pins up at once, thus eliminating the need to keep tension on the cylinder to hold the pins in place. Let’s just say that the material used for the blade is very important to say the least, and SLA just won’t do it. On the bright side, the robot does work, just very slowly.

Also consider adding rotational compliance between actuator and key. Measuring amount rotated will measure torque. Much more realistic than having encoder inside the door, plus it will reduce fatigue on the keys,” said one commenter.
