PHASE 1

Sense Head

First physical body. Everything later mounts under this. Maximum experience per dollar. Permanent skull and brain module.

ACTIVE Strong BOM

Done feels like

You walk in. Cameras wake. The head orients toward your voice, greets you, and logs show IMU plus video plus audio under a safety supervisor. Day-one embodiment.

Build order

  1. Read safety and the BOM. Inventory owned tools.
  2. Order long-lead electronics (compute, camera, servos).
  3. Print pan-tilt and skull (PETG). Heat-set inserts. Dry-fit.
  4. Wire dual rails and e-stop. Verify the servo rail dies on press.
  5. Bring-up: boot, camera 10 min, audio, IMU axes, slow servos.
  6. ROS 2 topics, look-at behavior, 30 min continuous demo.
  7. Journal the demo. Then you have earned Phase 2.
