The sheetmetal parts are looking great this year guys. Looking forward to seeing the completed robot. I'm interested to see exactly how you are powering the wheels as it appears to be dead axles (3/8" Grade 8 Bolts) but I don't see any pulleys or sprockets.

Looks like about an 1" of ground clearance. And I believe those slides on the front edge of the chassis (im guessing teflon, Delrin, or HDPE) allow them to go over the barrier, FRC2168 is doing something similar this year.

If you zoom into the picture, it looks as if the wheels are riding on hex shafts, if so, I'd imagine that the ends of the shafts have been drilled and tapped to allow the use of bolts as retainers.

That sheet metal work is absolutely gorgeous. Looking great so far! How high will your bumpers be?

FYI
Delrin is the Dupont trade name for Acetal.

That robot is definitely going over the bump.

I only have one question what is the angle of the thing in the front?

We are powering the wheels Via belt and pulley, similar to a west coast in some respects. It runs inside of the 2 C channels that make up one side of our drivetrain. The wheels are our custom 4".

Those are nice looking wheels, where did you get that black tread??

Very slick, folks!
