Subject: [PATCH 06/14] 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）

+## 💡 常见问题解答
+
+### 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)

+```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 08/14] 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 09/14] 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 10/14] 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 12/14] 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 13/14] 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.

- Added deadband and minimum effective threshold logic for motor inputs to improve precision.
- Introduced crosshair and mono font styles to the drive pad for better usability and feedback.
- Implemented snapping and clamping for motor values to ensure consistent control behavior.
- Added new manual and stop button behaviors with improved state handling.
- Included preset 3 button for extended functionality.
