TODO: Add encoder for servo control. The idea was to drive all 6 motors in the same direction for torque but when approaching the set-point reverse a few motors and provide backdriving to prevent over correction. You can drive 3 forward and 3 backwards to hold position.
Motor: ebay 3v 30RPM gear motor You will need 6 of these.
It is quite powerful but i forced it by hand too many times and striped the planets. The planets will need to be better than PLA to be useful.
