Good idea. I'll have to remember that.

Since Mech wheels need 4 transmissions, we planned on using the AndyMark Hubs and direct drive to save the weight of the chain.

That will leave you 6 to 7 inches between the motors. Real tight for a kicker. We did it, it is more complex than it looks. Installing bearings on the mechs with a sprocket is a simple operation.

Of course, now that I finally have all the information we need to order the Mecanum's and get them working (mechanically), they're now sold out. AndyMark is saying February 3, which means we won't be able to get them here until say, February 8 or so. That leaves us a a mere 2 weeks to get them built, mounted, and programmed. And then teach kids how to drive with them...........

I don't know what happened on their end, but I'm going to talk to the team about a redesign. I don't feel that's quite enough time.

If you want to keep your students buisy you could build some mechs out of ruber stoppers.
