TETRA V11 Updates

  • Modified motor mounts from previous version
    • Found that testing in real life with BBBxN&B N10s would get stuck and could not enter the hole made in CAD (exactly the dimensions of the N10), so expanded size by about 0.5mm
    • Added chamfers to the outside of the N10 mount so that it would be easier to force push the N10s inside
    • Because McMaster-Carr sells screws in almost bulk, it would be best to use the same screw all over the robot if possible to save money, so I found a way to get the screws used in the chassis to be used in the motor mounts when previous versions such as V9 used a different type of screw
  • Removed LED indicator (Malenki-HV has a LED, which I may use)
  • Filleted power switch mount to save weight on corners and reduce it potentially falling off
