A4 gearbox in line with motor
RLS encoder inside bracket
Current design challenges:
- Need to figure out mounting with A5/A6
- Need to make sure L bracket for A4 win't deform or fail

A5/A6 motors are vertical so that the belt transmission is symmetrical on both sides
Current differential is chonky - look to making it smaller
broadcoms still need to be integrated
Current design challenges:
- motor mounting flanges will need more support to prevent deflection
- look to reducing width of entire setup
