I have some questions though. Did you notice any flex in the frame when driving? It looks to me like it is all bolted together. I know people have had problems with frame flex in mecanum drive trains. One of the wheels would lift off the ground, messing up the resultant total force vector, sending the robot in another unforeseen direction.

Each wheel/gearbox pod pivots. The tennis and racket balls are what we are testing out for suspension springs. Right now, we are having more of an issue making the friction in the drive pods equal (we had one really beat up CIM in this chassis). If one wheel takes a second longer to start spinning then the same issue occurs.
Overall though our drivers were starting to be able to compensate for the quirks in the movement, so when we get it nice and tuned it should only get better
FIRST is a community unlike the public at large, with the distinction lying on its gracious professionalism. I have no doubt that the community will continue to uphold and cherish this unique characteristic through difficult events such as this. - Joon Park [more]
