We've built it in mind with having to place bumpers on the front of the robot, we were just curios as if we needed to or not. The arm does work with the bumpers there, but thanks for the heads up!

If the C-Channel is attached to the bumpers, it would not count as support, backing, or coverage. There has to be actual robot frame to connect to on the front of your robot.

We're aware, but a removable bracket bolted to the robot frame that the bumpers pin to does not count as part of the bumpers, thus it will count.

This design looks familiar

Fixing your bumper problem should be simple if the claw will still work with the bumper there.

Just bolt another tube across the front to provide "frame backing" and you'll be good.

What is the claw made out of? We made ours out of plywood, fiberglass, and chopped carbon fiber in '07; it was somewhat of a tour de force for our team at the time...

GL in Sactown!

We made it by epoxying two pieces of hexel together. It's quite light!

That's where we got some of our inspiration from

Like Kevin said, we epoxied two pieces of 1/4" plywood together and epoxied the outer rim to stabilize it. There are parts where we glued c-channel to the outside to prevent damage, but overall we expect it to be strong enough
We had a second damaged one without the siding or extra epoxying and one of the claw "jaws" held 50 lbs of downward force by itself before it gave way

In reply to your bumper fix, I guess great minds think alike That's what we did today once we realized that we had skipped over a crucial rule, seems to have worked well enough on our practice robot!


See you at Sac!!!

Hexcell***

Not plywood sorry!! xD


I'm curious for your claw this year, we saw the CAD but are still baffled

What kind of wheels are those? I know you've used mecanums in the past, but the render makes it hard to tell.

Also, anyone know how much it weighed? Looks light.
