We tried couple of things, which will not need changing it completely, but we were not able to do it. It looks like motors will need re-positioning, which we were trying to avoid. we will try again after this FLL season is over. The current Box robot is great, but with its weight and after adding attachments we can't go faster. It starts wobble. The taller wheels helps running faster. let us know if you are able to prepare one with taller wheels.
