Re: How to make the robot drive straight?

This could also be a hardware problem. If some of the motors are wired in reverse polarity, or if they're just older, they might not be able to reach the same maximum speed as they could if they were new and wired straight through. If any of your motors are wired up reverse polarity and receiving a +1 signal, try re-wiring them in straight through polarity and sending that side a -1 signal instead.
