Also, I really like this traction set-up. My team is planning a conceptually similar layout using four aluminum AndyMark omniwheels and two slightly modified AndyMark FIRST (2007 KoP) wheels driven by four CIMS. Your set-up will have all that ours has, and a bag of chips. Very nice work.  |
Thank you, also, for the compliment. We're all really proud of this drive.
Unfortunately, it looks like the other mechanisms that sit atop the frame won't allow for us to take much advantage of bumpers this season. While the bumpers aren't included in the 28 x 38 sizing requirements, the extra distance required to deploy things beyond them
is and we're not sure if it's worth the sacrifice.

I have a feeling that we'll need to support the back ends of the motors. Have you come across a similar issue?
Overall, I LOVE this setup. It's very similar to what you used last year, but the robustness is so much greater. One additional feature I would add is a row of 1/4" holes (spaced 1" apart) along the tops of all the rails, similar to the kit chassis. This allows you to mount whatever superstructure you want, where ever you want. We've done this with our sheetmetal chassis this year, nothing could be easier!

We'll be mounting some bracing across the top of the frame to accept the rest of the robot, so that should go a long way toward returning torsional strength to the frame tubing -- but so far, we haven't seen anything that makes us too worried about how well this will perform or how long it'll last.
