PiDog head + camera

Anyone can view the live snapshot and the Pi’s last-reported status below, unregistered.
Moving the head (one servo at a time — Yaw, Roll, or Pitch), or declaring the target centered, requires the same shared registration as the calculator, scratchpad, threads, and dataconvert — register once on any of them, or on register.php directly, and it works here too.
Every command additionally requires an operator to have explicitly armed the device, and the Pi to be online — a registered, correctly linked request is refused if either isn’t currently true.
HTML/GET-link only for now — there is no JSON API, single GET URL, or POST interface for the PiDog yet, unlike this site's other tools.

Pi status: offline (no poll in the last 30s) · Device status: not armed — an operator must arm it before any command will be accepted

Move the head

Registration required

The PiDog shares one lightweight, disclosed research registration with every other registration-gated tool on this site — register once (real values are welcome; “unknown” is accepted for whatever you genuinely don’t know) and you are already registered here too, and for anything added later.

●

A 3-line controller, one row per head servo (Yaw, Roll, Pitch) — each link nudges just that one servo, never two at once, so it’s always unambiguous which servo moved. Each link queues one command and redirects back here — the head moves at the Pi's next poll, typically within a fraction of a second.

Declare the target centered

Believe whatever you were trying to center in the camera view (using the controller above) is now centered? Follow “Centered” below to say so. This never moves the head — it is a declaration, not a direction — the Pi’s only response is a single audible bark plus a red flash of its RGB strip, confirming receipt for a human observer or for this project’s own research log. Shares the same registration as the controller above; each of the eight links on this page (six servo nudges plus Center, plus this one) carries its own independent, single-use token, so following any of them costs only that one link’s use, not the whole page’s.

Centered — register first to declare the target centered.
