PRELIMINARY - NOT APPROVED FOR CONNECTION, FABRICATION, MOTION OR ENERGIZATION

Explore all 19 native KiCad sheets.

The project now encodes the tether-first 12 V architecture, three regulated 9 V TTL rails, 25 individual actuator feeds and sourced controller-interface candidates.

Connected preliminary architecture

KiCad 10 ERC reports 0 errors and 0 warnings. That verifies encoded connectivity and annotation only. All protection values, physical energy/safety terminals, conductor sizes, grounding, stopping behavior, safety validation, and connection or energization authority remain open.
