I really like those gussets! Did you have them water jetted or milled? By the way, you can save a lot of weight up high by changing those bolts to rivets. Changing from bolts to rivets last year saved us upwards of five pounds over the entire robot. And, with a pneumatic rivet gun, rivets are fun to install.

Giant bumpers? Little robots?
Why not both?

Since, Akash is on the job, I'm sure there's no worry. I just couldn't find the main breaker in either front or rear shot. I hope it's more evident IRL.
Care to share any more detail about how the reversible covers work? The two-sided part is easy. It's those ends that look impossible.

As for the bumpers - I did not work on them myself, it was a small group of kids and a parent. I'll ask about the exact method used.

I second this. Rivets are lighter, and we too have a pneumatic riveter. Much nicer.

We don't have a pneumatic riveter and are quite low-budget. Our awesome machining sponsor also supplies materials. Yes rivets would be so much lighter, but where we are right now we may even have to weigh the drivetrain down. So it wasn't really a design issue. We had the nuts and bolts on hand so we used them.
tl;dr totally agree, but there was no need and we had bolts already.

What C-Channel is that? The holes are different than the KOP stuff, (I think) and how did you get it colored? It looks way better than just plain aluminum.

Cool! At least from the picture that looks a whole bunch better that just spray paint. Maybe it was the primer that you put on first?
