Re: pic: Team 1595 as of yesterday!!!

Guys,
After designing and fabbing these wheels last year we hit a problem that I would like to let you know before its to late. The yokes or brackets that hold the ends of the roller take a lot and i mean a lot of loading when making lateral movements, and or contacting any other robots/ramps. I made ours out of 1/8 6061-t6 with a small bend radius. Upon a few minutes of test driving we had a lot of bent yokes which lead to rollers hitting each other and the hub. We ended up with 11 gauge, (~.110) steel which worked like a charm, we also put a huge radius in the corners.

Hope it help.

We have actually driven the robot many times and we have not had any problems. We had a test chassis before this one and we drove it for at least 2-3 hrs total with no problems at all. We were driving it really hard to. Thanks for the concern though.



And we made the rollers from polyurithain(I just butchered that word!!!)

It looks really nice. One thing I'm looking at though is right in front, it looks like that plate would bend if hit, but, hey, I guess that's what bumpers are for right? Nice work.

It looks great, but it's difficult to discern many details because the pictures are so small.

Is there any chance you can upload the original photos to the CD-Media section of this website?

That'll help us make out the details a bit better and we'll be able to create a thread dedicated to your design instead of piggybacking on this one.

It isn't that bad with automatic feature recognition and being able to export parts from inventor.

Still...as long as you're doing it on a mill (Which it looks like, to me) and not waterjet, that'd take a looong time.
