How low do you go?

Well we have ended up with a chassis that is just 3/8" off the floor... Now to just get some electronics done and we should be rolling along!!

Re: How low do you go?

Be careful of that "BUMP" in the center of the field!!

Re: How low do you go?

Will that clear the 1/2 inch bump on the "lane markers"? Looks pretty cool through.

Re: How low do you go?

It does look awesome! Did you guys plan on it being so low as part of the design or did it just happen that way? I hope it isn't too low...

Re: How low do you go?

Our chassis is also low to the ground this year (about 1"). I would warn you that 3/8" is in my mind a very bad idea. Many things fall off robots during competition especially bolts. At 3/8" your robot could be high centered (or damaged) by a 1/4" bolt. Also the 1/2in bump in the center of the field could a major issue--I would recommend that if at all possible you modify your design.

Re: How low do you go?

I see you're using acetal sprockets. How well do those hold up to competition?

I've seen a few teams solely use them in their drivetrain; Out of the few I talked with, only one team had issues. I believe they had Acetal sprockets without metal hubs and cut keyways into that; those keyways eventually failed. The other teams used the metal hubbed ones or attached them with bolts/pins to the wheels in a dead axle application.

Re: How low do you go?

We're going to come up with a way to get a little more clearance just for precautionary measures.

Acetal sprockets?? We have use them many times before, but usually in a dead axle configuration. This is the first time we've tried it on a live axle. But also it is the first time we have gone with Hex axles. I doubt the Acetal will fail on 1/2" hex. Got to love those DuMont Hex broaches!! We have had them for two years now and finally get to use them
