+# naowalk
+
+A keyboard teleop client for the NAO robot: live video, walking, head control,
+two-way audio (hear the robot's mics, make it speak via TTS), and a YouTube
+music player that downloads a track with `yt-dlp` and plays it through the
+robot's own speakers.
+
+## Requirements
+
+**System packages** (Debian/Ubuntu names — adjust for your OS):
+
+```bash
+sudo apt install portaudio19-dev ffmpeg sshpass openssh-client
+```
+
+- `portaudio19-dev` — needed to build/install `pyaudio`
+- `ffmpeg` — needed by `yt-dlp` to extract audio to mp3
+- `sshpass` + `openssh-client` — used to `scp` downloaded tracks onto the
+  robot and to run `mkdir` over `ssh` (the script assumes the default
+  `nao`/`nao` credentials)
+
+**NAOqi Python SDK (`qi`)** — not on PyPI. Download the `pynaoqi-python`
+wheel that matches your OS/Python version from the Aldebaran/SoftBank
+Robotics developer site and install it:
+
+```bash
+pip install ./pynaoqi-*.whl
+```
+
+**Python packages:**
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+```bash
+python3 naowalk.py --ip <robot-ip> [options]
+```
+
+| Flag | Default | Description |
+|---|---|---|
+| `--ip` | `127.0.0.1` | Robot's IP address |
+| `--port` | `9559` | NAOqi port |
+| `--audio-device-index` | auto | Output device index for hearing the robot's mic on your machine |
+| `--mic-channel` | `left` | Which robot mic to stream (`left`, `right`, `front`, `rear`) — pick a working one, see Troubleshooting |
+| `--mic-gain` | `8.0` | Amplification applied to the streamed mic audio |
+| `--video-scale` | `2.0` | Display window scale (base feed is 320x240) |
+
+## Controls
+
+| Key | Action |
+|---|---|
+| `W`/`A`/`S`/`D` or arrows | Walk forward/turn/back |
+| `I`/`K`/`J`/`L` | Head pitch/yaw |
+| `Space` | Reset head to center |
+| `1` | Wave gesture |
+| `M` | Open music search (type query, `Enter` to search, `↑↓` to select, `Enter`/`1`-`5` to play) |
+| `P` | Pause / resume music (resume restarts the track from the beginning — see Notes) |
+| `X` | Stop music |
+| `-` / `=` | Volume down/up |
+| `T` | Type a message for the robot to speak (TTS) |
+| `Esc` | Quit (or cancel current mode) |
+
+## How it works
+
+- **`SoundReceiver`** — registered as a NAOqi service that receives the
+  robot's mic stream and plays it out your local speakers via `pyaudio`, with
+  gain and a prebuffer to smooth out network jitter.
+- **`NaoMusicPlayer`** — searches YouTube with `yt-dlp`, downloads and
+  converts the top match to mp3, `scp`s it to the robot, and plays it with
+  `ALAudioPlayer`.
+- **`NaoTeleop`** — the main loop: pygame window for video/input, keyboard
+  handling, head/walk control, and wiring everything above together.
+
+## Notes / design decisions
+
+- **No seek.** Seeking was removed entirely — it added the most complexity
+  for the least-used feature. `P` is a simple play/stop toggle; resuming
+  restarts the track from the beginning rather than tracking a playback
+  position.
+- **`moveInit()` on startup.** The robot used to need its walk buttons
+  jittered for a few seconds before its first walk would work. `run()` now
+  calls `ALMotionProxy::moveInit()` once at startup, which settles the walk
+  engine into the right pose before any real move command — this is the
+  documented NAOqi fix for exactly this symptom.
+- **`_safe()` helper.** Most one-off NAOqi calls (setting angles, volume,
+  stopping movement, unsubscribing services) are wrapped in a small
+  `self._safe(label, fn)` helper instead of a repeated `try/except` block, so
+  one failed call logs and moves on without crashing the teleop loop or the
+  shutdown sequence.
+
+## Troubleshooting
+
+- **Mic sounds dead / silent on one channel:** some robots have one or more
+  physical mics that produce no signal. Test all four with a quick energy
+  check, then pick a working channel with `--mic-channel`.
+- **Robot falls over on the very first walk command:** make sure you're on a
+  build that includes the `moveInit()` startup call described above; if it's
+  still happening, increase the `time.sleep(1.0)` after `goToPosture` to give
+  the posture more time to settle first.
+- **`scp`/`ssh` failures for music:** confirm the robot is reachable at
+  `--ip` and that `nao`/`nao` are still the correct credentials; the script
+  hardcodes them via `sshpass`.

+## chat-1
+
+> lets just gut the seek function and focus on what works. we also need to address the robot falling over if i try to walk from standstill, but only the first time i do it. If i jitter the walk forward and back buttons for about 3 seconds to get over the initial walk issues, it can start walking without falling over. how do we fix this
+
+Both very solvable. Let's do the walk fix first since it's the more important one — confirmed via NAOqi docs: `ALMotionProxy::moveInit()` is the standard fix for exactly this. It's a one-time blocking call that initializes the walk engine and settles the robot into the right pose _before_ the first real move command, which is exactly what your button-jittering was accidentally doing by brute force. It's missing from the script entirely.
+
+Now let's gut `seek()` entirely per your request — but keep the position tracking it shares with `pause()`, since that's still needed for resume-from-position to work:
+
+Right, orphaned body left over. Let's clean that up:
+
+Now remove the comma/period key bindings that called `seek()`:
+
+Now compile-check and confirm nothing else references `seek`:
+
+Clean. Let's ship it:

+## chat-2
+
+> alright awesome, lets remove the start from current position also, i want to get the lines of code down, what can be done without compromising on the stability and functionality to simplify our code
+
+Now let's do the full pass. First, the concrete simplification you asked for — remove position tracking, revert pause/resume to restart-from-beginning:
+
+Now `pause()` becomes a plain stop/restart toggle — no position math, no `playFileFromPosition`:
+
+Now let's cut the repetitive `try/except Exception as e: print(...)` boilerplate scattered through `NaoTeleop` — same safety, less code, via one small helper:
+
+Now let's add the `_safe` helper and apply it across these repeated sites:
+
+Now the `moveInit` startup call:
+
+Now the shutdown block — this is where it pays off most:
+
+Let's check the movement block and the `T` key's `stopMove()` call too:

+
+> kinda looks like hes flailing his arms around, isnt it just the elbows moving in the meme? with the arms in front
+

+
+> right motions, but the nao currently extends his arms out, then moves his elbows to push the forearms close to his chest. i think the rotation is wrong on the elbow
+
+That makes sense — at `ElbowYaw=0` the elbow's bend axis is oriented so flexing curls the forearm in across the body toward the chest, not up/down in place. Rotating `ElbowYaw` about 90° turns that same hinge into a front-facing "tip" instead, and I'll shrink the swing so it's a wobble, not a full extend-then-fold.

+> make him tts say six seven, also remove the input delay on starting the 3rd gesture
+
+`self.tts.say(...)` is a blocking call, so it was speaking first and only starting the arm motion once the phrase finished — that's the delay. Making it fire on its own thread lets the gesture start immediately while the speech plays alongside it.

+"""
+nao_video_server.py - RUNS ON THE ROBOT, under its own Python 2.7.
+
+Opens a qi session to NAOqi over localhost (zero network hop - it's
+the same box) and serves TWO persistent, length-framed TCP streams -
+one for compressed video (JPEG), one for compressed audio (mu-law) -
+each on its own port/connection. They used to share one connection,
+but a single big video frame mid-send could block audio behind it for
+its whole transfer time, which is a bad tradeoff for something as
+latency-sensitive as audio. Splitting them means a slow video frame
+can never delay audio.
+
+Why not HTTP: the phone tunnel only forwards specific TCP ports, so
+this still rides over TCP - but a 5-byte binary header has none of
+HTTP's chunked/multipart-boundary parsing overhead, and it's trivial
+to keep alive and reconnect on a flaky link.
+
+Why mic capture lives here now: it used to be shipped raw (16-bit PCM,
+uncompressed) straight through NAOqi's own pub/sub over the qi RPC
+session the client holds - i.e. across the tunnel, uncompressed, the
+whole time. Subscribing to ALAudioDevice locally (same zero-hop trick
+as the camera) means only mu-law-compressed bytes ever cross the
+tunnel, half the size of raw PCM.
+
+Wire format, identical on both connections (all integers big-endian,
+via `struct`):
+    1 byte   type     0x00 HELLO   0x01 VIDEO   0x02 AUDIO
+    4 bytes  length
+    N bytes  payload
+        HELLO payload: JSON, informational only
+        VIDEO payload: JPEG bytes (video connection only)
+        AUDIO payload: mu-law encoded 8-bit samples, mono (audio connection only)
+
+Under load (slow/lossy tunnel), video quality and frame rate step
+down automatically (see QUALITY_TIERS) and recover once sends are
+fast again - and since encoding is throttled to match, this also cuts
+CPU use on a congested link instead of just wasting it on frames that
+would've been discarded anyway.
+
+Needs the SDK's own env vars, since the bindings aren't on a login
+shell's default path:
+
+    export PYTHONPATH=/opt/aldebaran/lib/python2.7/site-packages
+    export LD_LIBRARY_PATH=/opt/aldebaran/lib
+    python2 nao_video_server.py
+
+Stdlib only (BaseHTTPServer/Flask are gone entirely now) plus qi,
+cv2, and numpy, which are already confirmed present on the robot.

-Standalone NAO audio diagnostic - deliberately bypasses naowalk.py entirely.
-
-Run this FIRST when troubleshooting "I can't hear the robot's mic". It tests
-each link in the chain independently, so a failure tells you exactly where
-the problem is instead of "somewhere in 300 lines of PyAudio/threading code":
-
-  TEST 1 - Front mic hardware energy.
-           Uses ALAudioDevice's built-in energy meter. No PyAudio, no
-           network audio streaming, no laptop audio stack involved at all.
-           This is the lowest-level check of "does the mic itself work".
-
-  TEST 2 - Local on-robot recording.
-           Records straight to a .wav file on the robot's own disk, then
-           you pull it off and play it normally. This bypasses the live
-           network stream, the SoundReceiver/queue/threading code, and
-           your laptop's PyAudio output path - all at once.
-
-  TEST 3 - Robot's own speaker.
-           Plays a tone through the ROBOT's speaker (not your laptop), to
-           confirm robot-side audio output is fine, independent of any of
-           the mic-listening code.
-
-If TEST 1 shows no energy change when you make noise: mic hardware/mute/
-environment issue, upstream of any code in this project.
-If TEST 1 works but TEST 2's file is silent: something is wrong with the
-recording/robot-audio-stack itself, still nothing to do with naowalk.py.
-If TEST 2's file has clear audio: the mic and robot are fine, and the bug
-is specifically in naowalk.py's live-streaming path (network delivery,
-PyAudio device selection, etc.) - go back to the diagnostics already
-built into naowalk.py (device list / test beep / peak level) to isolate it
-further.
