Cyclone is a conceptual shell-spinner 1lb combat robot with a fully thought out assembly, material selection, and wiring harness. This is not a melty-brain mechanism, but instead features a separate drivetrain while the full body spinner is able to rotate around a steel axis around which the bot is built.
The drivetrain: two N20 gear motors of 500 rpm translate rotational motion to a four wheel drive via equal gears along the side of the inner (non-spinning) body. This is essential for maintaining control during competitions to avoid pinning and create space for weapon spin-up time.
The weapon: Cyclone's full body spinner is bolted to a gear that utilizes rotational motion from the weapon motor--a 1700 kV drone prop brushless motor that also is to be fashioned with a dense 3D printed TPU gear, smaller than the body spinner to create a gear ratio that accommodates a large moment of inertia. This is necessary because of the AR500 steel "teeth" that are to be bolted into the wall of the body spinner.
