A1 Notes

A2 Notes

A3 Notes

  • Belt tensioner: Slots and linear screws

  • Shaft Stackup

  • Current design challenges:

    • High deflection on linkage - need to stiffen

A4 Notes

  • 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 Notes

  • 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
