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


Largetoni V1.0

  • 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


  • 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)


The fly wheel worked great!

The name LargeToni comes from the fact the our blade looks like an integral symbol. Our robot's name also needed to end with and 'i', which happens to be the first letter of the word integral. Therefore, we arrived at LargeToni, which is (almost) integral spelled backwards.
