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
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
