- 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.
- Mounting location for power switch.

Sandi still runs. It just doesn't run well.
