Fire Gimbal Control — Roadmap

Forward-looking plan for the software/firmware. Present-state docs live alongside this one (architecture.md, modules-reference.md, known-issues.md, …); this file records intent, not status. Keep entries dated; move shipped items into the reference docs.

Near-term / in progress

• Hardware self-test framework (test command). Modular on-rig validation with profiles, on-disk text reports, and baseline/drift comparison — replaces gimbal diag. Covers gimbal (homing, encoder, friction, backlash, balance), IMU (config, health, drift), and host/LattePanda (thermal, disk, memory, load). See test-command.md; tests blocked on not-yet-integrated components are tracked in test-roadmap.md.
  • Firmware support (next): a homing-report HM line (firmware-measured homing duration + endstop counts) and a load-capture LP primitive (peak/mean CS, SG, PWM during a move) so the friction/balance/homing-time metrics come off the firmware clock instead of host ST sampling; plus a PING/PONG link-health command for test system link.

Planned components & integrations

• MQTT → RabbitMQ migration. Move the control/telemetry channel onto the project's RabbitMQ stack. Decision pending between (a) RabbitMQ's MQTT plugin (near-zero firmware change, keeps QoS/retain/reconnect) and (b) native AMQP via a new IControlChannel implementation (richer routing/durable queues, but must re-engineer retained "last value" semantics). The abstraction seam already exists (IControlChannel). (TODO: confirm approach, target release.)
• RGB camera. Integrate the production RGB sensor end-to-end (acquire → JXL → CamEvent); enables the camera/rgb self-test. (TODO: model/SDK, mounting.)
• Thermal camera. Add the thermal sensor with radiometric handling (NUC, temperature range); enables the camera/thermal self-test. (TODO: model/SDK, calibration workflow.)

Cross-cutting / later

• Supply-voltage telemetry (bus-voltage sense → firmware) to enable gimbal/supply and brown-out detection. (TODO: hardware path.)
• Generic, multi-tower deployment. Continue removing site-specific assumptions (tower identity is already config-driven). (TODO.)
• Stubs to expand: long-term storage/offload, remote update, observability/metrics, security hardening.

Detailed, implementer-ready specs for tests blocked on the above hardware live in test-roadmap.md.
