Robotic head

This is a robotic head that I designed and built when I was 12. It had 3 motors with rubber band belt driven pulleys, that allowed the eyes to move left/right/up/down, and the mouth to open and close. It was actually built to the 1:1 scale of my younger brother’s head at the time. I drew up all the plans in 3d before so I knew how much wood that I would need, and even drew up a complete to-scale parts list for it, before starting building. It had a control box made out of balsa, with batteries and buttons so that I could control the motors remotely.

In my family that would be in reserve for a significant point in the brothers life when he would least expect it. Maybe a college graduation party or his wedding. In 2010 you could even add sound.

You should wire it up again, write a small routine for motion and post it to you-tube.

Best I ever did was motorize some eyes in a large pumpkin for halloween. I was watching from window of dark room and only would let one person notice them moving. If they pointed it out to another person I would go to straight front and freeze the motion. Great fun and probably the root cause for some soiled pants that year.

I smiled at the “brother’s head” part—pretty cool.

It’s fantastic.

Thanks everyone. I actually built one out of aluminum later on that had eyesight, hearing, neck movement, computer control… but being metal, I can’t post it here.
