You can have a max of 4 cims plus the motors included in the kop.


I would go with 6wd over mecanum in a heartbeat. Mecanums as mentioned have no pushing power and you won't be driving as fast around the field either. One problem with throwing the tubes to the center is you are increasing the chance for your opponents to grab it especially if you are the weaker drive. Yes there is some advantages with the lateral movement in front of the rack, but I'd take speed and pushing power over that.

A properly built 6wd and 8wd will have a turn radius of zero and waste no power.

Re: Mecanum or 6WD

6wd is the best because, not only is it faster and has more power, it can even be considered more manuverable than a mecanum. We tested this with our previous robots it takes 4 seconds with 6wd and 11 seconds with mecanum.

The rules say:
Quote:
<R45> Motors specifically permitted on 2011 FRC ROBOTS include:
A. all motors, actuators, and servos listed in the 2011 KOP Checklist,
B. an unlimited number of COTS servos with a maximum power rating of 4W ,
C. one or two CIM motors in addition to
those provided in the KOP. This means up to four CIM motors and no more can be used on the robot
