Engineering intelligence
Every panel below is computed by traversing the engineering knowledge graph — the same registries that drive the platform pages, the log, and diagnostics. Nothing here is written by hand, and nothing is stored twice.
Weekly engineering summary
Completed and active work, new logs and decisions, hardware and module activity, blocker movement, and upcoming milestones — derived from timestamps and relationships alone.

Decision impact
What each recorded decision affects, what depends on it, and how far its consequences reach — computed by traversal, never summarised by hand.
Specify the payload interface before building any payload

Design the motor and encoder mounts in-house

Keep the control link and stop path independent of the autonomy computer
Accepted · 4 Jul 2026Manual control and the stop path terminate at the ESP32 driver board, independent of the Jetson, so the autonomy computer can fail without the platform losing control authority.

Use a commercial rover base rather than fabricating a chassis
Accepted · 9 May 2026ERDEN Scout is built on a commercial 4WD rover base so early effort goes into autonomy and integration rather than mechanical fabrication.

Keep Utility a work platform, distinct from Scout

Start ERDEN Utility from a commercial electric utility vehicle
Accepted · 2026ERDEN Utility begins as a factory VEVOR four-wheel electric utility cart rather than a purpose-built work platform, so the engineering effort goes into control, safety, and autonomy rather than building a vehicle.
