When I set the motor power (both in RIS and nqc), I expected the speed
of the motor to be proportional to the power setting (i.e., higher power
setting makes motor turn faster and vice versa). However, what I see is
that the power setting appears to have no impact on motor speed.
Am I doing something wrong? Or is it just that I can't get there from
here? Any insights would be appreciated. (Yeah, I could do the PWM thing
in RCX code, but I hoped that the firmware did that sort of thing for
you; it would be faster and more efficient in firmware).
TIA
Cheers,

| The firmware does do PWM. One reason you aren't seeing much difference is that the motor has an internal flywheel. When the pulse is "on", the motor revs up to speed, then this speed is maintained by the flywheel during the "off" pulse. If you put a (...) (25 years ago, 17-Feb-99, to lugnet.robotics)
