I would strongly advise not to do anything like this in Lego League for multiple reasons

First there is the amount of motors used just to drive. Mine uses four, two for drive and two for steering. You will need a minimum of three motors to make an effective driving base leaving you with no powered special function (arm/claw).

Second would have to be the size of the robot. I got a chance to play with this robot a little bit on this year’s playing field and found that it was just small enough to fit threw most of the passage ways. Any slight variation of course would have caused it to either jam between something or destroy playing field pieces.

Next would be that you would need a minimum of two rotation sensor for any kind of accurate control. One for controlling steering and another for measuring distance.

The fourth reason would be alignment issues. Each wheel module is able to get slightly out of alignment from the others due to gear backlash. This is fine if you are driving it around with remote but makes autonomous control extremely hard because of its unpredictable curving when trying to drive straight.

All of these disadvantages add up and I think would really cause a lot of stressful meeting for the kids.
