Mecanum Drive Killing Battery

330 ran a 4-CIM drive between 2005 and 2008; I'm not sure about last year. No issues whatsoever with batteries (other than keeping them all charged during hours-long practice sessions in '07 and '08). All the robots were 6WD.

But, in 2005, the competition robot was designed to accept a mecanum drive. The Kitbot was equipped with that system for testing purposes; it didn't make it onto the competition robot. There were no battery issues on that robot.

With that being said... did it work out in your situation that you were running the CIMs with the desired current and still running at a decent speed? obviously you can design the CIM's to run at any current but if doing that means you are going to drive at a snails pace then it is kind of pointless. Was the robot that you are talking about able to drive with average speed without drawing too much current or was it slow?
