Your problem sounds like the motors on the right side might be wired opposite of each other. Put your robot on blocks to get the wheels off the ground and then try driving it. If the right side motors still act funny, either one is wired backwards, or you have some serious mechanical binding on the right side of the robot.

To check for the first problem, simply unplug/disconnect one of the right side motors and run the right side. Things should work just fine. Then plug in the other motor and unplug the one you just checked. Run the right side again, and make sure it's turning in the same direction as with the first motor. If they run in opposite directions, you're just identified the problem.

If they run in the same direction, turn off the robot and start looking for places you might have binding. Any place that a moving/turning thing comes close to a stationary thing is a potential place of binding. Grab a wheel and spin it and look/listen for anywhere the chain, wheel, sprocket, etc. might rub against the frame of your robot or some other stationary object.

We put it on blocks and after testing both motors individually, they both run in the same direction, so that isn't the problem. I can't identify any places where it is binding. But, they only start blinking after a sudden start or change in direction, when we begin slowly, they seem to work fine.
