What I quoted above is one of the most important things a team can do. Setting a baseline, and improving from it each year.
On FRC2168, we did the same thing this year, and intend to improve again on it for next year.
Things we improved on from 2011-2012:
- Moved from a 6WD to a 8WD to gain some stability (and to go over the barrier)
- Designing for Center to Center distance between axles to have exact chain or belt length
- Designing the tensioners in as standoffs as well (A 1" nylon rod with an off center thru hole, rotate to add tension)
- We continue to use 1.5" wide Colson Performa wheels with a
WCP hub and dead axles as we like the grip and the wear properties
Things we are looking to improve/add in the future:
- An Integrated braking system
- Belt Drive
- Reduce weight
- Increase efficiency (less gear reduction/better gearing selection)
- Attempt to decrease wheel diameter
- Improve packaging/modularity
About you question in wheel width, this topic has been discussed a number of times, with different answers. For us we have noticed that while our traction seems to be about the same, our tread seems to wear better with a wider contact patch. It's for this reason, and the amount of space they take up that we settled on using 1.5" wide wheels.
There are a ton of options out there in terms of wheel options, and even more for tread material. I strongly suggest exploring them.
