Here’s one way to do it…

I'm interested in this as well. Can you point me in the right direction? The link to a lesson or a video? I really appreciate it.

Unless you’re having problems with traction the best solution to drift is to use the tachometers (“encoders”) built into the motors.  Make sure you’re explicitly counting revolutions (and, knowing the wheel radius, you can thus compute distance).  A more simplistic use of time to compute distance will give you very unreliable and inconsistent results.

 

You can find videos on line on how to use the motor encoders to ensure the robot drives perfectly straight.

Usually weight issue as the robot is not balanced causes it..maybe its loaded with a lot of payload on one side.

Did any teams having issues with their robots drifting to one side instead for driving straight?  If so, how did you solve the issue?
