For 1114's rookie year, we used a plywood board with casters. Simple and effective.
Last year, as an off season project, we took a "garden cart" available at any number of stores(Walmart, Tuvalu, etc), and rebuild the rear Axel to incorporate a single drill motor with transmission and a set of variable diameter pulleys from
www.hi-lo.com . This gave us a very simple CVT transmission without any complex machining. (see attached photo) 494 built a set of variable diameter pulleys from scratch. They looked really slick.
Aside from that, a couple things you should note when constructing your cart.
-You should have storage for several batteries.
-Possibly a charger on-board. (especially at championship when you the pits are too far to go)
-Wheels should be large enough to roll over the covers the put over the audio/video cables at the venue.
-basic tools to perform minor repairs. (screwdrivers, Allen keys, zip ties, pliers)
- make sure to make it look really cool, it makes it easier for teams to remember you, which comes in handy for alliance selections
