Different Drivetrains

A pretty good picture of all our wheels + chain. It did pretty well for us, and I was amazed at how easy it was to turn the wheels by hand on an unpowered robot. Base team did a great job of chaining it. essentially 6WD, center drop, but each side had an additional 4 raised wheels to help with rockwall/moat/ramparts. We used the vex wheels in a 1.5" configuration so they couldn't get stuck in the rough terrain.

That paint job is sexy. 1x1 steel tubing I assume?

1x1x.125 aluminum tubing, welded, powder coated. We have a sponsor that can do welding for us so we were able to get by with 1/8" aluminum.

Also, this powder coated frame became our practice bot because we didn't come up with a rig for keeping axle holes aligned during the welding process =(. It was late in the season so we tried a fix by match drilling some plates and drilling out the axle holes on the inside runner for our practice bot (I'm surprised, but I can't find a good picture of it). Since it worked, we spray painted our frame originally intended as a practice bot frame and implemented the fix on the powdercoated frame during/after bag and tag. I liked to refer to our comp bot frame as the Ugly Duckling.

That stinks. Very few teams powdercoat their chassis, and it's a shame that yours couldn't be displayed in-comp. Performance over looks anyway, right?

It's a shame you guys couldn't make it to St. Louis, you've got a fine looking bot.
