The RCX uses pulse-width modulation to control power to the motor. The pulses are between 1ms and 8ms of power during an 8ms interval. In theory, this would result in different power being provided to the motor. The problem is that the motor has an (...) (25 years ago, 22-Jul-99, to lugnet.robotics.rcx.nqc)

I think that output power effects the modulation of the motor power. The motor power cycles on and off with the off time being longer at lower power settings. As David stated, this results in the same speed of the motor when it is unloaded for all (...) (25 years ago, 21-Jul-99, to lugnet.robotics.rcx.nqc)

I've had the same result. It seems an **unloaded** motor always runs at full speed. To explain it to myself, I've theorized that the 'p' (power) in Fwd() and OutputPower() is more akin to force and does not directly control velocity. Waiting for (...)

Just a note about a small bug. The supplied sample program ir-rover.cpp doesn't work on the real RCX. I think this may be due to IR complications under legOs. I'm working on a version which will work on both the emulator and the real system and will (...) (25 years ago, 21-Jul-99, to lugnet.robotics.rcx.legos)
