Controlling variance in drive train

[codedr]

We researched this. One solution is to make one side the master, and the other the slave.
You drive the master as you would normally, it's encoder output is the the PID target value for the slave.

Then if the slave is running slower than the master, the PID ensures it speeds up, and vice versa.

I've been wondering how exactly this would be done with Mecanum wheels.

We did something like this for our drive, except for us the master was the motor which spun slowest at full speed and the slave was the fastest motor, so they would occasionally switch while driving.

We are a rookie team and we are trying to use java to program our robot. We are noticing that in both auton and teleop, the robot is drifting. Several of you have mentioned using PID's and either encoders or gyros. Could someone post sample code of how to do any of the aforementioned solutions for a 6-wheel drive?

You could try this.
