Long-form: things I built, what worked, what didn't.
- About ESCs

VESC, BLHELI_S, AM32. The three ESC paradigms in the market, what each one brings (and costs), and why for the rebot's first version the call is to skip the VESC and run BLHELI_S on the loc with AM32 on the weapon.
- In practice, theory is something else.

Out of the analysis limbo, picking motors. Why a 6S direct-tangentially-driven loc is basically infeasible, the path that's left, and the weapon motor that hits spinup before a box rush can land.

Why a supersonic horizontal doesn't have to spin as fast as a vertical to hit harder. The math behind the "advantage factor" between the two geometries.
- It's dragging, bro

Aerodynamic drag isn't just relevant on an undercutter weapon, it's the limiting factor. Deriving the bar's real RPM, comparing 4S to 6S, and finding where volts-to-rpm stops paying off.
- Everything has limits

Breaking out of analysis paralysis with the project's constraints, project-wide and system-wide. A ceiling on every axis before CAD starts.

The tenets that will guide ReBot, a beetleweight undercutter built as an engineering project, not as self-expression.
