  • Results:
    • Single Elimination:
      • [L vs Humpti]
        • Both bot weapons failed to spin up so the entire fight was purely based off of driver skill and collisions. After the match ended, Humpti was deemed the victor by judges decision.

OTHER:

Problems

  • Original design was lacking structure
  • 3D printed weight varied drastically from CAD predictions (final bot was 3 ounces overweight)
  • Weapon motor mount did not account for belt tension so the motor itself was angled (weapon did not spin up)
  • Standoffs too short so back of the bot touched the ground
  • Did not account for tolerances in puzzle fitting or wheel slots

Good aspects

  • Driving was adequate
  • Wheels were well protected from other bots

Changes/Improvements

  • Make standoffs taller
  • Ensure that weapon motor mount accounts for belt tension
  • Be more efficient in estimating total weight
  • Add tolerances to puzzle fits, wheel slots, and weapon side plate holes
