When we do not invert one side we get:
forward command: all 4 wheels spinnning forward - won't go anywhere
***front wheel spinning forward back wheels spinning backward
reverse command: all 4 wheels spinning reverse - won't go anywhere
***front wheel spinning backward back wheels spinning foreward
slide right command: wheels 1 & 4 spinning forward; wheels 2 & 3 spinning backward
***this is what we get - slides right
slide left command: exact opposite of slide right
***this is what we get - slides left
I will check tonight when we get to the robot. We must have the left side of the robots PWM cables reversed on the digital side car. We are using the electronics board from last years robot and I know the PWM cables are bundled and zip tied. I also don't remember checking the digital side car end. We called out the PWM location by looking at the label we put on the PWM last year.
Thanks for all the idease! I'll post the solution when we get it figured out, hopefuly tonight.

what do the wheels do when you give a
spin command (clockwise and counterclockwise)?
If you map out what each of the four wheels are doing for each of the six commands, you can figure out what wires to swap, or, alternatively, you can fix it in software.
