Hello,

For my project I would like to mount the top half of this guy (weights 17 lbs):

And spin him at a speed of approx. 30 rotations/minute (twice the speed I can side step).

I would like the motor be start/stop operation.

The end goal is to have Bob rotate himself to position himself to face an opponent.

What motor is best to achieve this?

I have personally calculated a moment of inertia of 2.3 lb x ft^2

Hello @NickyMokrycke and welcome to the community,

Because the spinning speed you need is not high and sometimes you need to rotate it to a specific position the best option would be a dual-mode (continuous rotation and regular) high torque servo motor.
