Mecanum Drive Killing Battery

I am still interested in hearing about other teams experiences with running 4 CIMs on drive preferably on a mecanum chassis but if not that is fine as well.

Pretty much right on. I don't remember exactly where on the curve you want to design for with CIMs, but you do want to design them right.

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.
