This is a prototype animatronic tail, OpenScan designed 3D printed on a 3D printer and controlled by Arduino.

This is a small test:

I attached in a text document the code that use to control the servo with arduino.

Uses the number of vertebrae that want, i use 10 plus the final. I put a rubber cord in the side holes to keep the tail as, in the other holes, i put a normal string attached to the wheel. And so that the rope does not slip from the wheel put some small aluminum rings.

I hope you like ;)
