Competitions
2lb Competition 2021
- Results:
- Single Elimination:
- [W vs Varsiti]
- Mobility advantage made it easy to angle and attack
- Robots high drive speed made maneuverability difficult
- When the weapon made solid contact, it was able to flip and break armor

- [W vs Humpti]
- Ramp was a disadvantage in this match: stuck on tape and bots armor was low
- Humpti appears to lose control of drive about 12 seconds into the match
- Humpti gets flipped on its side and is disabled for the rest of the match

- [W vs Guillotini]
- Lost control of drive for a few seconds (most likely debris under wheel)
- Guillotini was unable to land a solid hit on us
- Flip Guillotini on its side (technically a KO)
- Guillotini regains control, informally decides to resume, and Largetoni breaks its armor and knocks LiPo out

Problems
- HDPE axle was poorly improvised and not secure properly (too few threads, should've used Loctite)
- 3D printing manufacturing made it difficult to gauge weight and plan ahead
- Ramp caught on ridges and other imperfect surfaces - bot would have to build up speed to avoid getting stuck
- Wheels were too close to the frame and rubbed on side plates
- Strong hits are reliant on bots being secured against a wall
Good aspects
- Weight was concentrated at the back of the bot, making driving reliable
- Unique shape made it difficult to land a solid hit on the armor
- Weapon shape and upward spin made it great for flipping
- Ramp prevented bot from hitting the wall with the weapon
Changes/Improvements
- Longer weapon shaft
- Keep better track of weight (avoid speed holes)
- Make skids work such that the bot always lands on the wheels - we removed the skids because we couldn't fix this issue in time
- Have more clearance between wheels and side plates
- Make ramp geometry flatter and thinner in CAD (avoid having to sand at the last minute)
- Program the remote for less jerky movement (hyperbolic/non-linear response curve on drive stick)
Notes:
The fly wheel worked great!
