Amazing! Nice work. Glad to see bot rise above the doubt some of us had. Any videos planned?

Re: pic: 6 wheel omni drive

impressive design and manufacturing of that for sure, i am interested in the ball diff. your going to be using for those center wheels. Also, that's a nice set of custom mecanums. Keep up the good work, i'd personally like to see more teams trying crazy ideas.

Re: pic: 6 wheel omni drive

Is there any type of suspension for the mecanum wheels?

Re: pic: 6 wheel omni drive

Very nice design--really unique!! I, too, am looking forward to some video of it driving around.

I see the two round bars that space the left-side and right-side modules, but how does the sheet metal "belly pan" mount to them, since the distance between the two bars will change as the suspension flexes?

Re: pic: 6 wheel omni drive

Lots of questions. Vidio http://www.youtube.com/watch?v=urFsD0gA1D4
Its not a good vidio but it works.

More pictures and drawings of the ball diferental http://www.team1322.org/ideas.htm

I will be taking pictures of the ball differental soon for our web sit.

The picture with the aluminum plate is for demostration only. A frame would be attached to the two rods and one of the drive halves will be slotted to allow the suspension to work. I have not made the slots yet but will. The whole idea is to allow for ramp use with mecanum wheels and also give alitle more pushing in forward. The final design will have the gear boxes go right into the mecanum wheels. This means if I order everything from bain bots and anndy mark and make the side plates I can throw the whole thing together in no time. The ball differental was easy to make. The wheel took awhile to make but we had all the stuff show in our inventory.

Re: pic: 6 wheel omni drive

is it really worth the extra weight to drive the center omni wheels, they won't add much to your pushing force. there is also the added drag of the chain and differential.

Re: pic: 6 wheel omni drive

We are actualy going for the suspension. Any extra traction would help.

What if we install 4 sets of mecanum wheels and 8 sets of omni wheels on each drive half? Would that give more push power?

I don't think we would try it but what if?

Yes it will give you marginally more pushing power, but only marginally and not enough to be worth the extra weight and system drag.

Re: pic: 6 wheel omni drive

Up date to this post:
we used this drive system for our 2010 robot and it did well. in pushing matches it did make a difference, we were able to hold our own. The suspension worked great for the humps of the soccer game.
you can view the completed robot at http://team1322.org/ideas.htm
