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
