I'm not a professional or anything, but your idea could run into the robot
pulling to one side, and not going the exact 1 meter.
if you had two rotation sensors (not exactly RPM sensors), the error would
be greatly reduced in both the distance and the pulling to one side.
Or if you don't have any rotation sensors, you could use touch sensors to
measure the rotations of the wheels.
My humble suggestion,
Timothy
