SO basically you guys(111) lifted the back of your base and used the front to tank, am i right? do you think if we take off the tread and use a different form of belting like the black ones from mcmaster( not treads on them, just plain black plasticy not sure what material)

question for 258- did you guys use treads last year i cant seem to remember?
Akshay,
Our swerve had the drills and CIMs like yours. We used the same tread that you have in that picture you linked to for the Silicon Valley Regional, and we didn't have any trouble with normal tank style driving. We changed to a different read that was more resistant to the wire mesh for Cal Games, but only for that reason. Our modules were geared to go about 10 feet per second on 6" diameter wheels. Our setup also had our two drill modules in the front of the robot, and our two CIM modules in the rear (although we had a mode where we could rotate all the modules 90 degrees, and then change the front of the robot to whataver direction they rotated towards). Not that that mattered much last year.

Here are a couple links to some pictures of our modules...

PS - I'm glad to see another CA team tackle swerve in such a challenging year to do so. I can't wait to see your robot in person
