I am pretty sure anyone building a lock picking robot is at least aware of some lock picking basics, and that's clearly not the point of a project like this. They could get a Lishi, a rake, a comb, almost anything, and we could also argue that this won't work with pin-in-pin dimple locks, tubular locks, and disc detainers, but again, obviously not the point.
This is a fantastic idea for a community challenge! Would have to make some ground rules though or else the winning bot is just a diamond coated drill or a gallium squirt gun.
