This is VERY similar to my team's last two drive trains. This kind of system is very adjustable and easy to build. It's worked great for us these last two years.

Some things to consider:
5.79 fps is probably a little two slow. We ran low gear at about his speed this year and it was useless. The slowest I would go is 7 fps.

You could save more weight with #25 chain. This system makes chain tensioning a breeze, and you could easily implement #25. We used #25 this year and never lost a chain.

I'm curious as to why you put the axles on the center line of the extrusion. It would be a lot easier to put the pillow blocks on the top or bottom. You could save a lot of machining, and replace the 1020 with 1010.

Altogether great work though. Are you gonna build a prototype?

i saw that u guys used pneumatic wheels on the 2007 robot...we were going to use that this year but we couldnt find a way to mount sprockets on. Were those sprockets custom or were they bought?
