(...) Well, if you read my *long* post from a week or so ago, you'll know that motor mismatch makes up at least 11% of performance, motor direction perhaps 1% or at most 2%, and HOW YOU BUILD YOUR MODEL accounts for at least 7% ... even when you are (...)

(...) I guess - but surely - having an asymmetry in the robot's construction is more likely to cause it not to drive straight than the 1% to 2% due to the motor rotation direction. You may be a 'better' builder than I am - and perhaps be able to (...) (23 years ago, 23-Jan-01, to lugnet.robotics)
