How you build it
Four steps, one evening.
In order, because the order matters. No soldering.
- 01
Check the servos
Both arrive already addressed and centred: pan on ID 1, tilt on ID 2. Power them up and confirm each answers before anything is bolted shut.
- 02
Build the head
Camera into the chin, speaker behind the grille in the back cover, a cheek on each side. The board lies face down in the front shell; plug in the camera, the speaker and four wires, then close it up.
- 03
Build the neck and base
Both servos go into the neck. The head slides back over it onto the tilt horn, the wires drop down through the neck, and the neck sets onto the base with one screw from underneath.
- 04
Wire the adapter
The adapter goes into the base. Servos into its sockets, the board’s 5 V and ground to its terminal, TX to RX and RX to TX. Cover and feet on, then the 5 V supply into its barrel jack.
