Subject: [PATCH 06/18] feat(camera): add camera lifecycle management and API
 endpoints

- Introduced threading-based camera lifecycle state management.
- Added API endpoints for camera control: start, stop, switch, and state.
- Implemented camera index handling and switching logic.
- Updated video feed and face detection routes to check camera state.
- Enhanced `/api/faces` endpoint to include camera running state.

+```
+
+**特点**:
+- ✅ STA 模式（作为客户端连接现有 WiFi）
+- ✅ 自动 mDNS 广播
+- ✅ 实时连接状态反馈
+- ✅ 串口日志输出
+
+### 2️⃣ OSC 控制协议
+
+```
+/motor           # 设置速度 (-255 ~ 255)
+/motion           # 执行运动模式 (1-6)
+/stop                   # 停止电机
+```
+
+**支持的运动模式**:
+| 模式 | 名称 | 时长 | 命令 |
+|------|------|------|------|
+| 1 | 缓慢摇晃 | 4s | `/motion 1` |
+| 2 | 快速旋转 | 2s | `/motion 2` |
+| 3 | 脉冲抖动 | 1s | `/motion 3` |
+| 4 | 加速螺旋 | 3s | `/motion 4` |
+| 5 | 平滑制动 | 1.5s | `/motion 5` |
+| 6 | 脉冲启动 | 2s | `/motion 6` |
+
+### 3️⃣ 串口控制协议
+
+```
+motor            # 设置电机速度
+motion            # 执行运动模式
+stop                    # 停止电机
+info                    # 显示设备信息

+
+```cpp
+void sway(int amplitude, int duration)           // 摇晃
+void fastSpin(int duration)                      // 旋转
+void vibrate(int intensity, int duration)        // 抖动
+void accelerateSpin(int maxSpeed, int duration)  // 加速
+void smoothBrake(int initialSpeed)               // 制动
+void pulseStart(int targetSpeed, int duration)   // 启动
+```
+
+### 5️⃣ 电机正反向控制
+
+通过 GPIO 23 控制方向：
+
+```cpp
+// GPIO23 = HIGH  → 正向旋转
+// GPIO23 = LOW   → 反向旋转
+// GPIO22 PWM值   → 速度控制（0-255）

+### Q: 为什么需要 GPIO 23？
+A: 单个 PWM 引脚只能实现单向旋转或速度控制，不能同时控制方向和速度。GPIO 23 控制方向，GPIO 22 控制速度。
+
+### Q: 能否支持多个电机？
+A: 可以。在硬件上添加更多 GPIO 对和对应的驱动电路，在软件上添加更多电机对象。
+
+### Q: 如何扩展运动模式？
+A: 在 `kait_v2.ino` 中添加新函数（参考现有 6 个模式），然后在 `executeMotionMode()` 中添加 case 分支。
+
+### Q: 支持哪些操作系统？
+A: Arduino IDE 和 Python 都是跨平台的（Windows/macOS/Linux）。
+
+### Q: 最大连接距离是多少？
+A: 取决于 WiFi 信号，通常 50-100 米。可通过增强 WiFi 路由器信号改进。

+
+## 🔍 调试技巧
+
+### 1. 验证 WiFi 连接
+
+通过 mDNS 访问：
+```bash
+ping F7OWER_kait.local
+```
+
+或者通过路由器查看设备 IP
+
+### 2. 使用串口监视器
+
+在 Arduino IDE 中打开串口监视器（波特率 115200）查看实时日志
+
+```
+✅ WiFi已连接，IP: 192.168.1.100
+✅ mDNS 已启动: http://F7OWER_kait.local
+✅ OSC 监听端口: 8888
+```
+
+### 3. 测试运动模式
+
+按顺序测试每个模式：
+```bash
+python3 kait_osc_debug.py -i F7OWER_kait.local --seq test_all
+```
+
+### 4. 调整参数
+
+在 Python 脚本中修改延时和速度参数测试不同的运动效果
+
+## 🎨 自定义运动模式
+
+### 在 Arduino 中添加新模式
+
+1. 在 `kait_v2.ino` 中添加新函数（参考现有模式）
+2. 在 `executeMotionMode()` 中添加对应的 case 分支
+3. 更新 OSC 协议文档
+
+### 在 Python 中添加新序列
+
+在 `kait_osc_debug.py` 或 `kait_serial_debug.py` 中：
+
+```python
+def sequence_my_custom(self):
+    """自定义序列描述"""
+    print("\n🎨 执行序列: 自定义运动")
+    # 添加你的运动逻辑
+    self.set_motor_speed(150)
+    time.sleep(2)
+    self.stop()
+    print("✓ 序列完成\n")
+```
+
+然后在 `_list_sequences()` 和 `_run_sequence()` 中注册
+
+## ⚠️ 故障排除
+
+| 问题 | 原因 | 解决方案 |
+|------|------|--------|
+| 电机不动 | 未给启动冲击 | 检查 GPIO 23 连接（方向控制） |
+| 速度不可控 | PWM 冲击时间过长 | 调小 `MOTOR_KICK_START_DELAY` |

+
+## ⚙️ 配置调整
+
+### WiFi 参数（编辑 kait_v2.ino）
+
+```cpp
+const char* STA_SSID     = "F7OWER";           // WiFi 名称
+const char* STA_PASSWORD = "12345678";         // WiFi 密码
+const char* MDNS_NAME = "F7OWER_kait";         // 设备名（mDNS）
+const int OSC_PORT = 8888;                     // OSC 端口
+```
+
+### 电机参数
+
+```cpp
+const int MOTOR_KICK_START_POWER = 255;        // 启动冲击功率（最高=255）
+const int MOTOR_KICK_START_DELAY = 30;         // 启动冲击延时（毫秒）
+```
+
+调整这两个参数来改变：
+- `POWER` 越高，启动越猛烈
+- `DELAY` 越长，启动冲击持续越久
+
+## 📡 OSC 命令速查

+| `/motion` | 1-6 | `/motion 1` | 执行模式 1 |
+| `/stop` | 无 | `/stop` | 停止电机 |
+
+### 运动模式快速参考
+
+```
+/motion 1  →  缓慢摇晃 (3~4秒)
+/motion 2  →  快速旋转 (2秒)
+/motion 3  →  脉冲抖动 (1秒)
+/motion 4  →  加速螺旋 (3秒)

+## 💻 使用流程
+
+### 步骤 1: 上传固件
+```bash
+Arduino IDE / PlatformIO
+→ 打开 kait_v2.ino
+→ 选择 ESP32 开发板
+→ 上传
+```
+
+### 步骤 2: 配置 WiFi
+编辑 `kait_v2.ino`:
+```cpp
+const char* STA_SSID     = "你的WiFi";
+const char* STA_PASSWORD = "密码";
+```
+重新上传
+
+### 步骤 3: 验证连接
+```bash
+ping F7OWER_kait.local
+```
+
+### 步骤 4: 开始控制
+
+**OSC 方式**（网络远程）:
+```bash
+python3 kait_osc_debug.py -i F7OWER_kait.local --interactive
+```
+
+**串口方式**（有线本地）:
+```bash
+python3 kait_serial_debug.py --list-ports
+python3 kait_serial_debug.py -p /dev/ttyUSB0 --interactive
+```
+
+### 步骤 5: 可视化查看运动效果
+```bash
+python3 kait_motion_visualization.py --all
+```
+
+---
+
+## 🔧 配置参数（可调）
+
+### 电机启动参数
+```cpp
+// kait_v2.ino 中修改
+const int MOTOR_KICK_START_POWER = 255;   // 启动冲击功率（0-255）
+const int MOTOR_KICK_START_DELAY = 30;    // 启动冲击时间（毫秒）
+```
+
+### WiFi 参数
+```cpp
+const char* STA_SSID = "F7OWER";           // WiFi 名称
+const char* STA_PASSWORD = "12345678";     // WiFi 密码
+const char* MDNS_NAME = "F7OWER_kait";     // mDNS 名称
+const int OSC_PORT = 8888;                 // OSC 端口
+```
+
+### 运动模式参数
+
+可在 `kait_v2.ino` 中修改各函数的参数，例如：
+```cpp
+sway(80, 3000)              // 摇晃幅度 80，时间 3 秒
+fastSpin(2000)              // 旋转时间 2 秒
+vibrate(120, 1000)          // 颤动强度 120，时间 1 秒
+```

Subject: [PATCH 08/18] feat(kait): add comprehensive API reference and
 delivery checklist

- Created `API_REFERENCE.md`, detailing OSC commands, motion modes, sequences, and firmware APIs.
- Added `DELIVERY_CHECKLIST.md`, providing a thorough package validation and content summary.
- Completed English translation for all documentation and scripts.
- Updated `kait_osc_debug_en.py` with sequence functions and an interactive mode.

+- Restart computer after driver installation
+- Try different USB port on computer
+
+---
+
+## ⚙️ Configuration Parameters
+
+### Firmware Settings (Edit `kait_v2_eng.ino`)
+
+```cpp
+// WiFi Configuration
+const char* STA_SSID     = "F7OWER";           // WiFi name
+const char* STA_PASSWORD = "12345678";         // WiFi password
+const char* MDNS_NAME = "F7OWER_kait";         // Device broadcast name
+
+// Motor Configuration
+const int MOTOR_KICK_START_POWER = 255;        // Startup kick power (0-255)
+const int MOTOR_KICK_START_DELAY = 30;         // Startup kick duration (ms)
+
+// Network Configuration
+const int OSC_PORT = 8888;                     // OSC listen port
+
+// Hardware Pins (Do Not Change)
+const int MOTOR_PWM_PIN = 22;                  // Speed control pin
+const int MOTOR_DIR_PIN = 23;                  // Direction control pin
+```
+
+### Adjusting Motor Startup
+
+The firmware includes "kick start" to overcome static friction:
+
+- `KICK_START_POWER`: How hard the initial pulse is (255 = maximum)
+- `KICK_START_DELAY`: How long the pulse lasts (milliseconds)
+
+If motor starts too aggressively:
+- Reduce `KICK_START_POWER` to 200
+- Or reduce `KICK_START_DELAY` to 20
+
+If motor won't start at low speeds:
+- Increase `KICK_START_DELAY` to 40
+

+
+## 🐛 Troubleshooting
+
+### Motor Won't Move
+
+- Check GPIO 23 connection (direction control)
+- Verify power supply to motor driver
+- Test with `--motion 1` (gentle sway)
+
+### Can't Connect to WiFi
+
+- Verify SSID and password in firmware
+- Check that WiFi is 2.4 GHz (not 5 GHz)
+- Re-upload firmware with correct credentials
+
+### Can't Find Device
+
+```bash
+# Try using IP address instead of mDNS
+# Check your router for connected devices
+# Default attempt: 192.168.1.100
+python3 kait_osc_debug_en.py -i 192.168.1.100 --speed 100
+```
+
+### Serial Port Issues
+
+```bash
+# On macOS/Linux:
+sudo chmod 666 /dev/ttyUSB*
+
+# Or run with sudo:
+sudo python3 kait_serial_debug_en.py -p /dev/ttyUSB0
+```

+## 🔐 WiFi Security
+
+The firmware connects in **Station Mode** (STA), meaning it joins your existing WiFi network:
+
+- **SSID**: Your WiFi network name
+- **Password**: Your WiFi password
+- **mDNS Name**: F7OWER_kait
+- **Access**: Available as `F7OWER_kait.local` on your local network only
+
+For security:
+- Only your local WiFi devices can access it
+- It does NOT create a public access point
+- Connection is local-network-only
+
+---
+
+## 📊 Performance Specs
+
+| Specification | Value |
+|---------------|-------|
+| **PWM Frequency** | 20 kHz |
+| **Speed Range** | 0-255 |
+| **Resolution** | 8-bit (256 levels) |
+| **Startup Delay** | ~30 ms |
+| **Network Latency** | <50 ms (LAN) |
+| **OSC Port** | UDP 8888 |

Subject: [PATCH 09/18] feat(ui/sequences): add sequence recording, playback,
 and management

- Implemented motion sequence recorder with label-based organization.
- Added `/api/sequences` endpoints for saving, loading, and listing sequences.
- Extended Flask app tests to cover sequence API.
- Updated frontend with sequence recording, playback features, and status tracking.
- Enhanced UI accessibility with `aria-label` attributes.
- Adjusted camera selection route to use specific backend for macOS compatibility.
- Refined Kait node UI with motion modes and motor speed controls.

Subject: [PATCH 10/18] feat(tracking): add face-tracking coordinate publisher
 and serial communication support

- Implemented `CoordinatePublisher` for face-tracking data via OSC or USB serial.
- Added `SerialCoordinateSender` with pyserial integration and serial port handling.
- Introduced `/api/tracking/config` and `/api/serial/ports` endpoints for coordinate tracking and serial communication.
- Updated UI with tracking transport switch and serial connection status.
- Added Arduino-based ESP32 firmware for servo-based face tracking via OSC or serial.

Subject: [PATCH 12/18] feat(serial): add lazy pyserial loading, raw serial
 command API, and UI controls

- Implemented lazy loading for pyserial modules to optimize app startup time.
- Added `/api/serial/raw` endpoint for sending raw serial commands and handling errors.
- Updated `/api/serial/ports` endpoint to support optional scanning with `scan` query parameter.
- Enhanced UI with serial debug command field and improved manual motor and drive pad controls.
- Updated tests to cover new API endpoints and serial behaviors.

Subject: [PATCH 13/18] refactor(ui): streamline camera and device control
 code, remove unused Sylvie motor functions

- Simplified camera list population logic and improved error handling.
- Removed deprecated Sylvie motor and drive pad functionality.
- Introduced helper functions for refreshing devices and tracking configuration.
- Enhanced LED, OSC, and device control operations for clarity and consistency.
- Added fallback logic to improve device list handling during scans.

Subject: [PATCH 17/18] feat(host-ui): merge ViT emotion detection and reactor
 pipeline with UI updates

- Integrated ViT-based emotion detector with fallback support into perception pipeline.
- Added Emotion Reactor for smoothing, mapping, and live OSC command generation.
- Updated `/api/faces` to include perception and reactor data.
- Enhanced UI with real-time flower emotion status, analysis table, and reactor tuning sliders.
- Added `/api/reactor/config` endpoint for runtime adjustments.
- Extended tests for ViT emotion, reactor logic, and UI additions.

+# Upgrade Summary Report
+
+Date: 2026-03-16
+
+## Scope
+Merged `python_host_emo` emotion capability into `python_host` using a minimal-risk architecture:
+- Kept existing camera lifecycle and multi-node panel structure.
+- Added perception + reactor pipeline for `human_emotion -> flower_emotion -> node_command`.
+- Added concise UI status for live flower emotion state.
+
+## What Changed
+
+### 1) Backend integration in `python_host`
+- Added `PerceptionModule` usage inside `python_host/ui/app.py`.
+- Started perception only when camera starts (`_start_camera`).
+- Stopped perception when camera stops (`_stop_camera`).
+- Extended `/api/faces` response:
+  - `perception`: model outputs (including `vit_emotion` when available)
+  - `reactor`: smoothed flower state and command telemetry
+- Extended `/api/perception/status` to include `vit` availability.
+
+### 2) ViT emotion support
+- Added `python_host/vision/vit_emotion.py`.
+- Updated `python_host/vision/perception.py` to:
+  - load optional ViT detector
+  - emit `vit_emotion` payload with `dominant`, `confidence`, `scores`, `classes`
+
+### 3) Emotion reactor
+- Added `python_host/vision/emotion_reactor.py` with:
+  - score pool + decay smoothing
+  - enter threshold = `1.8`
+  - exit threshold = `1.0`
+  - min hold = `1500 ms`
+  - command cooldown = `1200 ms`
+  - no-face timeout = `2500 ms`
+  - asymmetric dynamics:
+    - `BLOOM/ALERT` gain is higher and supports burst-trigger transitions
+    - `SOOTHE` gain is lower and defaults to longer hold for recovery
+    - shock term amplifies high-confidence `BLOOM/ALERT` detections
+  - runtime tuning support via `/api/reactor/config` (GET/POST)
+- Flower state set:
+  - `BLOOM`, `ALERT`, `SOOTHE`, `REST`
+- Human-to-flower mapping:
+  - `happy/surprise -> BLOOM`
+  - `angry/fear/disgust -> ALERT`
+  - `sad/neutral -> SOOTHE`
+  - no face timeout -> `REST`
+
+### 4) Node command mapping
+Implemented in `EmotionReactor`:
+- Sue:
+  - `BLOOM -> /state relax`
+  - `ALERT -> /state danger`
+  - `SOOTHE -> /state calm`
+  - `REST -> /state idle`
+- Kait:
+  - `BLOOM -> /motion 2 or 6` (round-robin)
+  - `ALERT -> /motion 3 or 4` (round-robin)
+  - `SOOTHE -> /motion 1 or 5` (round-robin)
+  - `REST -> /stop`
+- Sylvie:
+  - `BLOOM -> /preset 1`
+  - `ALERT -> /preset 2`
+  - `SOOTHE -> /preset 3`
+  - `REST -> /preset 3`
+
+### 5) UI update
+Updated `python_host/ui/templates/index.html` with a compact "Flower Emotion" status block:
+- state label + emoji
+- source emotion + confidence
+- 0-100 stability bar
+- color per flower emotion (soothe green, alert red, bloom yellow, rest gray)
+
+Added a full "Real-Time Emotion Analysis Table":
+- sorted per-emotion score rows
+- score bars for quick reading during demo
+- model tag (`vit` or fallback source)
+
+Added live "Emotion Reactor Tuning" sliders:
+- enter/exit threshold, decay
+- bloom/alert/soothe gains
+- shock scale
+- soothe hold time
+- values sync to backend immediately (runtime only, no restart)
+
+## Dependency updates
+Updated `python_host/requirements-ml.txt`:
+- `transformers>=4.30,<5.0`
+- `torch>=2.0,<3.0`
+
+## Tests updated
+- Updated `python_host/tests/test_flask_app.py` to assert merged API keys (`perception`, `reactor`, `vit`).
+- Updated `python_host/tests/test_perception.py` for `vit_emotion` and lazy ViT loading.
+- Added `python_host/tests/test_emotion_reactor.py` for baseline reactor behavior and mapping coverage.
+
+## Notes for demo
+- This iteration prioritizes reliability and explainability over deep nonlinear mapping.
+- Reactor is intentionally coarse and deterministic for showcase stability.
+- Advanced sequence-conditioned mapping and LCD eye animation are left for post-showcase iteration.

Subject: [PATCH 18/18] feat(host-ui): enable multi-target emotion dispatch and
 global scheduling modes

- Added support for dispatching reactor commands to multiple emotion targets.
- Introduced global emotion scheduling toggle for manual control suspension.
- Updated UI with mode selection buttons (Safe, Balanced, Dramatic) to adjust reactor behavior.
- Added per-device emotion routing toggle with backend integration via `/api/devices/emotion_targets`.
- Enhanced Flask app with new endpoints for emotion override states and multi-target routing.
- Improved tests to cover new functionalities and edge cases.

 ## What Changed
 
+### 0) Startup auto-scan
+- Updated `python_host/main.py` to run one automatic LAN device discovery pass at startup.
+- Discovered devices are registered immediately so no manual scan click is required before emotion routing.
+
 ### 1) Backend integration in `python_host`
 - Added `PerceptionModule` usage inside `python_host/ui/app.py`.
 - Started perception only when camera starts (`_start_camera`).
@@ -64,6 +68,25 @@ Implemented in `EmotionReactor`:
   - `SOOTHE -> /preset 3`
   - `REST -> /preset 3`
 
+### 4.1) Multi-target emotion dispatch mode
+- Reactor target source changed from single selected device to current checked device list.
+- Added per-device routing selection in backend and UI:
+  - `GET/POST /api/devices/emotion_targets`
+- Behavior:
+  - scanned + known in `device_registry.json` => auto-checked for emotion routing
+  - scanned but unknown => not auto-checked
+  - manual checkbox controls participation in emotion-driven OSC dispatch
+
+### 4.2) Global emotion scheduling switch
+- Added `GET/POST /api/reactor/override`.
+- UI switch: `Emotion Override (Manual Takeover)`
+  - ON => emotion scheduling active (default)
+  - OFF => manual-only mode (emotion routing suspended)
+
+### 4.3) Node Controls manual target binding
+- Clicking node-type tabs now auto-selects a matching discovered device (by type, deterministic order by IP/port).
+- Manual OSC commands in Node Controls therefore route to the correct selected device automatically.
+
 ### 5) UI update
 Updated `python_host/ui/templates/index.html` with a compact "Flower Emotion" status block:
 - state label + emoji
