I think it was one of the drive motors that came with that Cybot from Real Robots Mag. Then yeah it just had a 9v battery there, used a servo to touch 2 peaces of wires together to turn it on. It wasnt an ant, just a bot i made with the spare servos i had to play with. The disc is the bottom of a coke can. LOL Then super glue to the motor shaft. Very safe. LOL. I bleieve the motor was about 12,000rpm at 4.8v and was running it at 9v, so god knows how fast it was going... waited for it to spin off. LOL!!
