  • Results:
    • Bracket Style:
      • Loss vs. Silent Spring
        • Sandi's wheels were not stock, and the different left and right wheels caused the robot to drive in arcs.
        • Silent Spring's weapon disk slipped between the baseplate and ring assembly, shearing the screw of a ring support.
        • Sandi's ring was spinning at such high speed that it still hit Silent Spring's weapon, shattering it, throwing the robot across the arena, and affecting its steering.
        • Sandi's ring was unable to spin up again due to the lack of support; eventually, the hubs slipped the drive axles on both sides of the robot, disabling it and resulting in a loss by KO.
      • Loss vs. Ghoti
        • Sandi (for a yet unknown reason) could not drive as well right side up as it could upside down, so its mobility was hampered.
        • Ghoti went in for a hit, as Sandi would not easily move towards the other robot.
        • The impact knocked both Sandi's wheels off axle due to the concussive force, disabling its movement. Ghoti was tossed and landed upside down, its bar bent by the impact.
        • Due to its initiation of contact, Ghoti won by KO.

Problems:

  • Hubs and wheels slipped off of motor axles with enough force applied to the robot.
  • Non-stock wheels made the robot almost undriveable.
  • Ring would spin down and not spin up again easily after hitting any object (tested at full speed with plastic water bottle).
  • Ring slipped off of supports at certain locations along its track.
  • Large open space between ring assembly and robot baseplate is an opening to attack.

Good Aspects:

  • Weapon was one of (if not the most) powerful in the 3lb class.
  • Can operate when flipped, although was far more effective on one side than the other for some reason.
  • Robust support network can allow several supports to be taken out and the robot still be viable after repairs.

 Changes/Improvements:

  • Use common screw sizes so multiple esoteric hex keys are unnecessary.
  • USE STOCK WHEELS.
  • POSSIBLY plastic baseplates and motor mounts to save weight.
  • More precisely machined ring assembly and teeth in order to prevent slippage and imbalance.
  • Smaller components in order to save room for the internals.
  • Less space between ring assembly and baseplates.
  • Better skids.
