I am just finishing up building the InMoov Robot head. First you must know that there are about four revisions for every part. For instance I did the earlier version of the eyes first. They had very limited range of motion. So I made a newer version and they had much better movement.
I also tried painting the parts for the first time. I used paint-able caulk first, then several layers of a sand-able undercoat followed by at least 2 layers of paint. This next picture shows the results.
This is what it looked like before painting, the holes have been filled with caulk. I do not know why there are so many holes in the design!
This is what the eye assembly looked like. I modified it slightly to fit an older Logitech webcam guts. However the camera was upside down when it was tested.
I modified the gear for the mouth and the ears as well. I wanted ears that were fairly flat, but that resulted in the magnet hitting the jaw mechanism. I will have to find some lower profile speakers.
I also located and added a base. The real inMoov robot has more than just a head, but I wanted to stop there for now. I had to cut the throat piston off at about one inch shorter to fit properly with the stand.
Here is what the completed robot head looked like.
I also recorded a video of me testing the servos to see if everything worked. I used some MG958 servos that are twice as powerful as standard servos but I was not sure if they would be powerful enough.
