(...) That's not really any different from what the RCX's firmware does though. You are doing pulse-width modulation and so does the firmware. The only difference is that you are using a longer time-constant. ---...--- Steve Baker ---...--- Mail : (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

Changing the motor 'speed' (pulse wave modulation) really only changes the torque. It will only change the speed if the motor is heavily loaded. Another technique that is more successful is to create a control loop in which the motor is on for 5 (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

(...) It's possible - but if you crank up the resolution you soon run into the problem that your software cannot run fast enough to keep count of the pulses. Also, it's hard to distinguish clockwise from anticlockwise rotation with a (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

For the robotics class I teach (& FLL team), I have RIS 2.0 (& 1.5) on multiple computers running Win98 and/or Win2000. No problems with either OS. Called Lego for support with a sound problem (had to get a new sound card compatible (...) (23 years ago, 26-Apr-02, to lugnet.robotics)

(...) There are commands for the RCX to use different 'power levels' - which will translate into a change in speed if there is sufficient load. (...) lego (...) No - but you can use a gear train to make the rotation sensor spin more than once for (...) (23 years ago, 26-Apr-02, to lugnet.robotics)
