In this video, I show a different approach to accurately position things with the N20 miniature geared motor. Originally, these geared motors come with a magnetic encoder installed on the motor’s shaft, but based on my experience so far, they are not too accurate for positioning. This is mainly due to the fact that there is a wonky gearbox between the actual driven shaft and the motor. This gearbox suffers from backlash which messes up the positioning. It is not super noticeable when the motor drives a lead screw, but it becomes very bad when circular motion is needed, for example when the shaft of the gearbox should position a wheel on a 0360° coordinate system.
