Hey all.

Just wanted to clarify a few things. Our rollers were cast from urethane rubber, at a derometer of 80. We had to play around with the derometer a bit until we settled on this one, it gives a good balance between pushing and release of friction.

Also, the type of mecanum wheel we decided on came after looking at all of the different designs, including those used by 190. Here are the reasons we chose the type we did:
-Our wheels require a significantly less amount of parts
-The orientation of 190's rollers have them being held externally on either end. This gives significantly less ground clearence and also more exposed materials. The fact that our rollers are held on the inside give us much more clearence and keeps parts unexposed.
-The design we chose has two separate rollers at one position, while the other designs call for a single large roller. This large roller prevents friction from being released as steadily, and therefore draws more power without delivering more pushing power.

Keep the questions rolling...
