Robotic sputnik tool, it is very slick. Something that's not obvious is that these work best on ABUS or other locks that have one solid driver pin and spools in every remaining pin stack. This way, when you locate and lift the solid driver pin, you gain a ton of "back and forth slack" in the plug. As you lift each successive spool driver the slack reduces until the shear line is hit on that pin stack and suddenly full slack again; repeat the process until the lock is open.

The devil is in the details though, there are some subtle features that need to be incorporated into the mechanics for the sputnik to work right. I have built a sputnik from scratch before, only after talking to Oli Diederichsen at a LockCon did I get some additional clues.

Also, I think there are plenty of other interesting things one could do besides brute forcing the lock with a simpler tool. Falle Safe has a single-wire variant on this for decoding locks. Again, the devil is in the details, just ramming wire up a pin stack doesn't get the job done.
