Re: pic: 3247 Robopack Frame Design
A Cimplebox is not suitable for direct driving a six inch wheel. Did you "do the math" and figure out what your gear ratio would be?
Yeah, the 1/4 plate you have in the front and back are securely attached to the robot, but Madison's concerns are valid. It's not so much the plates physically moving as much as them parallelograming. (Is that a word?)
Easiest way to fix both these issues would be to drop a Toughbox Mini in (with an appropriate ratio) and to add the AndyMark standoffs between the gearboxes, in addition to any "additional support" you might have planned (e.g. replacing the front and back pieces with C-channel or tubing). A rigid belly pan would also help a little.
