A few years back, I became interested in
attempting to propel a wheeled robot using
stepper motors. This is not the usual method
for propelling a robot. A more typical
approach is to use two traditional DC motors.
Individual differences in the two DC motors
are then accommodated by optical feedback
that provides data which can be used to
match the speed of the two motors.
