My team has been trying to think of ways to make the drive system more accurate. One of the things we came up with is using shaft encoders to make sure the wheels would be spinning at the right speed (eg: instead of setting the PWM speed to drive, you use the joysticks to set the speed you want the wheel to be rotating at so if both joysticks are full forward, the robot will go straight, regardless of motor inconsistencies).
Has anyone had any luck with these? I have been doing some reading, but I would like to hear what other people have to say.
