Does the Lego USB IR tower, when set to long range, sometimes draw more than the 500mA allowed? Or do laptops generally not reliably supply 500mA? Or are we facing some deeper analog issue here, like not ramping up to 500mA from less mA fast enough (...) (22 years ago, 12-Feb-03, to lugnet.robotics.rcx)

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 (...)
