Introduction

Chonki is a 45lb shuffling shell spinner competing in the 30lb weight class. It was developed during 2020-2021. The drive system was iterated from that of Apachi. The weapon system was a brand new concept for BattleBots. The goal of Chonki was to evaluate the viability of shell spinners while taking advantage of the 1.5 time weight multiplier afforded by using a mechanism other than wheels for movement. Has not been to competition due to COVID cancellation, but showed promise during development.

Drive System

Chonki utilizes a shuffler system for drive. It consists of two shuffler modules, each with 4 HDPE feet.

Weapon System

Nested Concept

Originally the shell was designed as a series of rings with progressively increasing diameters. The method of joining these rings together was thoroughly discussed. The two primary options were use of fasteners and through welding.

Fastener Method

Pros:

  • Avoids need to use welding (process with which we had little experience)
  • Simple to align via hole placement in ring
  • Easy to replace damaged bolts and or rings

Cons:

  • Bolts are likely to shear under stress from hitting other bots
  • Addition of holes to rings add stress concentrator, increasing likelihood of failure
Welding Method

Pros:

  • Very strong joint between rings if done correctly
  • Difficult to align rings and keep them aligned (flats were included on rings for this purpose, but a jig would still be required)

Cons:

  • A single piece means the whole thing must be replaced after damage
  • Welding is hard lol

Solid Concept

Instead of doing the nested concept, we simply decided to kill the Earth and mill the shell out of a massive block of steel.
