Thread: animatronic robot eyes

Tweet

was on Ebay researching some stuff I am selling and I found these. Not sure how useful they would be, but it looks like a cool piece of hardware.....

All I can think is creepy doll prop.

The problem would be controlling the motors. Since they aren't RC servos, any control circuitry would have to be custom made along with the software. MAYBE a PropX or some other micro controller would work, I don't know. According to the ad, replacing the motors with servos is a big maybe.

It would be interesting if anyone has hacked one of those Alive Elvis' to hear how they did it.

since they have low voltage motors, and 3 wire POT feedbacks, i would assume it would be easier, to pull control boards from 4 servos and use them as the control interface, desolder the motor leads and resistors, from the servo control board and attach them from these eyes.

or you can just buy http://cgi.ebay.com/Animatronic-robo...item1c132e5f55 about the same price and already use servos for movements.
