Robots tilt

[sanddrag]

I'm not really sure how angled wheels would provide easier turning (I have seen teams do this for some odd reason I've yet to understand), but in a 6wd setup, many teams choose to lower the center wheel so that there can be at most 4 wheels on the ground at any given time. I've found 3/16" offset to be sufficient. Personally, the rocking (tilting) with 3/16" offset was a bit of an annoyance for me. But this was for the Triple Play game where we were trying to place a tetra with a long arm. I'd split the difference between 3/16" and 1/8" and set it at 5/32" (if you keep tolerance on these sort of things to that small). Of course it somewhat depends on what tires/tread you are running. Anything over 3/16" I think would be excessive and anything below 1/8" would be too small.

We have done this for the past two years with great success. Our
2004 robot had a four wheel design with 4WD, and we had many problems with turning. Our 2005 and 2006 robots
had 6WD with the center wheel slightly lower than our two outer wheels. If you use a pneumatic wheel for the center, you can adjust how offset the center wheel is.
