Weapon System

Shell Design

Shell was milled out of a 250 lb block of A36 steel. It took forever but was very effective in absorbing damage.

Pros:

Cons:

• Expensive, had to get Speed Machine to have them use a larger machine to mill the shell out.
• One piece, parts that got damaged on shell were not replaceable - dents needed to be pressed or hammered out.

Weapon Shaft Interface

A tapered roller bearing fits into a housing that is attached to the top of the shell.

Weapon-Drive Mechanism

• • Inspired by Hyperpolarized, it was later decided to drive the weapon by using a single driven wheel at the top of the bot, with rollers along the surface to give additional support. A central shaft was used as a dead axle support.

Chassis System

• The chassis mostly consisted of aluminum, featuring of a ¼” top and side plates and ⅛” bottom plate.
• The front and back plates were made of HDPE, which bent to form Chonkii’s robustly round shape.
• The chassis had multiple rollers spaced out along its top, giving additional support to the shell track above.
• The central dead axle was constrained by two blocks, mounted to both the top and bottom plates. However, it was later determined that a single longer block with a key would constrain the shaft better than the two block system.
  • While drilling through the blocks into the shaft, a drill bit melted inside, acting as a makeshift pin (that was instantly destroyed in competition).

Competitions

Motorama 2022

• Results: 1-2
  • Bracket Style: Double Elimination
    • [Anarchi (loser) V.S. Wedgeham (loser): YouTube Link]
      • Match started with Wedgeham overwhelming Anarchi with it's superior driving by raming into us and pushing us into the wall repeatedly
      • Anarchi never tried to spin it's weapon up to maximum velocity due to the fear of self damage.
      • Anarchi landed a few small hits on wedgeham but none enough to do any significant damage due to the weapon not being able to reach it's max velocity
      • Half-way through the match, the gear boxes got internally damaged, slowing down our drive and our ability to move
      • When time hit 3 minutes, Wedgeham was the decided winner due to it being able to prevent us from spinning up or moving properly
