The ring 236 can provide mounting points for the cover 262 to encase the internal structure 204 of the enclosure 200. In the example of
Similar to the frame 234, the ring 236 can be made from any suitable material that can withstand extreme temperature swings and weather various environmental conditions. However, in most implementations, the suitable material for the ring 236 must be somewhat more durable than the material used for the frame 234. This is because the gear teeth 250 of the ring 236 are subject to more wear and tear from being coupled to the powertrain of the frame 234. The ring 236 can be fabricated using various metal alloys (e.g., carbon steel, alloy steel, etc.). The ring 236 can also be fabricated with three dimensional printers using thermoplastics (e.g., polylactic acid, acrylonitrile butadiene styrene, polyamide, high impact polystyrene, thermoplastic elastomer, etc.).
