Getting the bot to go straight?

[Hawiian Cadder]

with the drill motors that was an issue. cims gain bias the older and/or more used they are, so i would recommend against using cims from prior robots, or more than 2-3 years old. (replace the motor, keep the gearbox, if you are worried about costs.)

our team used to always use drive straight code. this year, for the first time since i joined the team, the robot drives perfectly straight, without any code.

A longer wheel base will also improve your bots ability to drive in a straight line. (Notice: This also makes turning your robot much more difficult. Which.. well... is why your bot will drive straighter....)
