I don't know what you're talking about ;)

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

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.

GL in Sactown!


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 :D

In reply to your bumper fix, I guess great minds think alike :D 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!!!

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.
