OK, time to add the motors to control the head and neck. These are simple surplus 12v motors with a simple machined cam to rotate the head and neck to simulate a coordinated movement using the push rods. When they move they trigger a limit switch set for “normally open” and that sets off the CF3 sound to play a series of phrases from Star Wars to entertain the kiddies…… Very simple, very easy. All initiated with a 4 channel remote. I use a Radio Shack microphone stand as the support for the droid.
