Wheels turn at different speeds

We have assembled our GoPiGo, however the wheels are turning at much different speeds. Is there a way to control how much power each motor gets? Is there another way to solve this issue? Thank you!

Have you run the update script from the desktop shortcut? We had made some changes with this problem after the GoPiGo came out so this should help you out if you have already not done it. Just make sure that the Motors are disconnected before you try this.

Also, do try running the GoPiGo on the floor, the motors use PID so they should automatically tune once the GoPiGo starts.

One more thing, can you just check if you have both the encoders on there and the opaque film that was on them is still there.

Let me know if you still have any problems.
