I have included a link for the .step file of the chassis now
I included a lot of the changes you guys suggested
I still have to include the rest of the electronics and figure out a tensioning design but that will come later
The red things on the wheels are the colson live axle hubs
http://wcproducts.net/wcp-00053/
The blue things on the aluminum channel (seen from the bottom of the robot) are AndyMark hex bearings with flanges
http://www.andymark.com/product-p/am-0279.htm
The hole in the aluminum channel is slightly smaller than the OD of the bearing so they will be pressed in and there is a small flange on the bearing which will keep it from going too far.
Also the axle is now hex and the pulley has a hex bore so they are connected
Do you guys have any more comments or suggestions?
Your help has been very useful so far, im learning a lot
