Kit Chassis + Mecanum = Flex

Some of the NERDS were helping team 3194 at the Arizona regional. One problem they had was with drive chains falling off. The robot is pretty simple, it uses a kit chassis, with AM mecanum wheels driven with the kit style toughbox and mounting design, one motor and transmission per wheel.

The design of the chassis, transmission mounts, and wheel towers allows some flexing. This is made worse when the towers are cut away for wheel clearance.

I helped the team analyze the problem, and this is the fix they came up with. Simple, effective.

Also, notice the sleeve in the picture, this is the best dressed team I've ever seen! (Thanks to their sponsor JC Penny)
