oh wait, HA, I invented that... lol :-)
It's amazing that we were easily able to push around Wildstang's 4 CIM swerve with traction control AND Winnovation's tank with traction control...

Just because your driving me up the wall Swttrt224 by taking all the credit I would Like to lay down the blame for this drive train and answer others questions.
Firstly, this drive train is the result of a study swttrt and others including myself did last year. The math for the gear ratio with some real world tweaking is swttrt's, the actual drive train that was cut by a student on the team and framing around the drive train that was built by big1boom was all Cadded by me. As such why I am extremely disappointed when all the credit for this drive is taken by one over zealous member.
An additional note that I would like for other members of my team to understand is that they must remain gracious professionals when on these forms and need to stop gloating. Is it true that this drive train has yet to find a match that can push it as adequately, yes. Is it true that this robot did not win the Midwest regional, yes. Is it true that my members have just explained exactly why we have so much traction, yes. Do I expect that because of their posts we will have lost our advantage, yes.
Since they have been so forward about our robot I feel that It is only right to post up some CAD's I drew. These Cads where used to build our drive train. I will try to explain what was used for what.
This is the original idea before we found out that Caterpillar could not produce any parts for us due to economic issues.
So we made a frame that looks like this with the same chain and electrical Ideas as previous.
we actually milled these with a 20 year old cnc that we got working 2 weeks before ship and taught ourselves how to cut. Not the notches that allow our bit to make right angles where we need them. - this was milled by both 1/8 inch and 1/4 inch end mills. Thanks to my sophomore team that learned how to run the machine we finished on time.
Those last 2 should give you an idea of the bevel gear set up, the plates are placed so that they keep the bevel together while taking into account the bushings.
The aluminum is just 1/8 in thick, and thank goodness cause it helped keep the weight down.
The lazy suzans are from mcmaster.- a note to my sophomore's as I will me graduating this year, use a smaller chain next year.
I had a great time cadding this, and It really helped modularize our build cause it stated the exact placement of the ball system and electrical.
