With that low of a ground clearance I take it you're not going over the barrier this year?

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.

What size are the wheels? I don't really have a good perspective to tell if they are 4" or 6".

In block form, Delrin has been used as a chain tensioner in the past--stick the block in so the chain is slightly too tight and let it find its own tension by digging into the block.

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

That robot is definitely going over the bump.

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

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

Thanks for the questions and compliments everybody, I will try to answer some of the questions the best I can.

My only criticism is that 2826 doesn't share our regional schedule this year...

You guys better qualify for St. Louis!

Very slick as always! Can't wait to see the rest of it in Duluth!
