Go to Post It's always nice to have the outside party take a look at your code because one of two things can happen: 1. They write it better. 2. They find your stupid mistake. - [more]

In the picture posted, the piston is located under the black mounting plate, and adjacent to the blue one (its the grey cylindrical object in the cad). From what they told me, it was designed to test out and eliminate the twitching that the modules may have when trying to drive in a straight line. Because the control system tries to compensate the drift, and then over-corrects the action, the piston would lock in to the appropriate groove when needed and make sure the robot drives in a straight line.

They did mention that they would have to do some more testing with the current design since the motor was able to overcome the piston lock fairly easily.
In some ways that sound like a cool solution, and thinking outside the box. But it also sounds like they're fixing a software problem with hardware.
Regardless of my mixed feelings about this. I'd be very interested to hear if it helped or not.
