Re: pic: More fooling around with mecanum wheels

If the wheels were 2.5" instead of 3", I'm not sure why this is infeasible at a first pass. I think this design would be robust enough for a FRC bot on a flat field under 2 conditions: 1.) The lexan that supports the outer edge of the dead axle were replaced with C-Channel and 2.) The robot frame only mounts to the C-Channel.

3"x1.5" C-channel with 0.2" leg thickness would work great. The added ounces of the Aluminum C-Channel would be offset by leaving the gearbox plates as polycarbonate. All robot impact forces resolve through the C-Channel, and the polycarbonate only needs to be strong enough to rigidly cantilever the CIM as shown.
