if self.metric3d and hasattr(self.metric3d, 'cleanup'): - self.metric3d.cleanup() -``` - ---- - -## Test Suite Documentation - -### Test File: `test_drone.py` - -The test suite contains 7 critical tests, each targeting a specific failure mode: - -#### 1. `test_mavlink_message_processing` -**Purpose**: Verify ATTITUDE messages trigger odom publishing -**What it tests**: -- MAVLink message reception -- Telemetry dictionary update -- Odom message publishing with correct data -- Quaternion presence in published pose - -**Critical because**: Without this, drone orientation isn't published to ROS - -**Test implementation**: -```python -def test_mavlink_message_processing(self): - conn = MavlinkConnection('udp:0.0.0.0:14550') - - # Mock MAVLink connection - conn.mavlink = MagicMock() - attitude_msg = MagicMock() - attitude_msg.get_type.return_value = 'ATTITUDE' - attitude_msg.to_dict.return_value = { - 'mavpackettype': 'ATTITUDE', - 'roll': 0.1, 'pitch': 0.2, 'yaw': 0.3 - } - - # Track published messages - published_odom = [] - conn._odom_subject.on_next = lambda x: published_odom.append(x) - - # Process message - conn.update_telemetry(timeout=0.01) - - # Verify odom was published - assert len(published_odom) == 1 - assert published_odom[0].orientation is not None -``` - -#### 2. `test_position_integration` -**Purpose**: Test velocity integration for indoor positioning -**What it tests**: -- Velocity conversion from cm/s to m/s -- NED to ROS coordinate conversion for velocities -- Position integration over time -- Correct sign conventions - -**Critical because**: Indoor drones without GPS rely on this for position tracking - -**Test implementation**: -```python -def test_position_integration(self): - # Create GLOBAL_POSITION_INT with known velocities - pos_msg.to_dict.return_value = { - 'vx': 100, # 1 m/s North in cm/s - 'vy': 200, # 2 m/s East in cm/s - 'vz': 0 - } - - # Process and verify integration - conn.update_telemetry(timeout=0.01) - - # Check NED→ROS conversion - assert conn._position['x'] > 0 # North → +X - assert conn._position['y'] < 0 # East → -Y -``` - -#### 3. `test_ned_to_ros_coordinate_conversion` -**Purpose**: Test all 3 axes of NED↔ROS conversion -**What it tests**: -- North → +X conversion -- East → -Y conversion -- Up (negative in NED) → +Z conversion -- Altitude handling from relative_alt field - -**Critical because**: Wrong conversion = drone flies wrong direction or crashes - -**Test implementation**: -```python -def test_ned_to_ros_coordinate_conversion(self): - pos_msg.to_dict.return_value = { - 'vx': 300, # 3 m/s North - 'vy': 400, # 4 m/s East - 'vz': -100, # 1 m/s Up (negative in NED) - 'relative_alt': 5000 # 5m altitude - } - - # Verify conversions - assert conn._position['x'] > 0 # North → positive X - assert conn._position['y'] < 0 # East → negative Y - assert conn._position['z'] == 5.0 # Altitude from relative_alt -``` - -#### 4. `test_fake_mavlink_connection` -**Purpose**: Test replay mode MAVLink message handling -**What it tests**: -- FakeMavlinkConnection message queue -- FakeMsg.get_type() returns 'mavpackettype' field -- Message replay from TimedSensorReplay -- Correct message ordering - -**Critical because**: Replay mode essential for testing without hardware - -#### 5. `test_fake_video_stream_no_throttling` -**Purpose**: Test video replay without frame rate throttling -**What it tests**: -- FakeDJIVideoStream returns stream directly -- No ops.sample(0.033) throttling applied -- Stream object is returned unchanged - -**Critical because**: Throttling would desync video from telemetry in replay - -#### 6. `test_connection_module_replay_mode` -**Purpose**: Test correct class selection in replay mode -**What it tests**: -- Connection module detects 'replay' connection string -- Creates FakeMavlinkConnection instead of real -- Creates FakeDJIVideoStream instead of real -- Module starts successfully with fake classes - -**Critical because**: Must not attempt hardware access in replay mode - -#### 7. `test_connection_module_replay_with_messages` -**Purpose**: End-to-end replay mode integration test -**What it tests**: -- Full replay pipeline with multiple message types -- Video frame replay and publishing -- Odom computation from replayed messages -- Status/telemetry publishing -- Verbose output for debugging - -**Critical because**: Verifies entire replay system works end-to-end - -**Test implementation** (with verbose output): -```python -def test_connection_module_replay_with_messages(self): - # Setup replay data - mavlink_messages = [ - {'mavpackettype': 'HEARTBEAT', 'type': 2, 'base_mode': 193}, - {'mavpackettype': 'ATTITUDE', 'roll': 0.1, 'pitch': 0.2, 'yaw': 0.3} - ] - - # Track published messages with verbose output - module.odom = MagicMock(publish=lambda x: ( - published_odom.append(x), - print(f"[TEST] Published odom: position=({x.position.x:.2f}, {x.position.y:.2f}, {x.position.z:.2f})") - )) - - # Start and verify - result = module.start() - assert result == True - assert len(published_odom) > 0 -``` - -### Running Tests - -```bash -# Run all drone tests -pytest dimos/robot/drone/test_drone.py -v - -# Run with verbose output to see test prints -pytest dimos/robot/drone/test_drone.py -v -s -

---- - -## Running the System - -### Complete Setup Process - -#### Step 1: Android Device Setup with RosettaDrone - -1. **Install RosettaDrone APK** (see [Android Setup & DJI SDK](#android-setup--dji-sdk) section) -2. **Connect Hardware**: - - Connect Android device to DJI RC via USB cable - - Power on DJI drone and controller - - Ensure Android device is on same network as DimOS computer - -3. **Configure RosettaDrone**: - - Open RosettaDrone app - - Go to Settings → MAVLink - - Set Target IP to DimOS computer IP - - Set ports: MAVLink=14550, Video=5600 - - Enable Video Streaming - -4. **Start RosettaDrone**: - - Tap "Start" in RosettaDrone - - Wait for "DJI Connected" status - - Verify "MAVLink Active" status - -#### Step 2: DimOS System Setup - -### Prerequisites - -1. **System Dependencies**: -```bash -# GStreamer for video -sudo apt-get install -y \ - gstreamer1.0-tools \ - gstreamer1.0-plugins-base \ - gstreamer1.0-plugins-good \ - gstreamer1.0-plugins-bad \ - gstreamer1.0-libav \ - python3-gi \ - python3-gi-cairo \ - gir1.2-gtk-3.0 - -# LCM for communication -sudo apt-get install liblcm-dev - -# PyTorch for Metric3D (if using depth) -pip install torch torchvision -``` - -2. **Python Dependencies**: -```bash -pip install \ - pymavlink \ - rx \ - numpy \ - dask \ - distributed -``` - -### Basic Usage - -#### 1. Start with Real Drone -```python -from dimos.robot.drone.drone import Drone - -# Initialize drone with UDP connection -drone = Drone( - connection_string='udp:0.0.0.0:14550', - video_port=5600 -) - -# Start all modules -drone.start() - -# Get current status -status = drone.get_status() -print(f"Armed: {status['armed']}") -print(f"Battery: {status['battery_voltage']}V") - -# Get odometry -odom = drone.get_odom() -if odom: - print(f"Position: {odom.position}") - print(f"Orientation: {odom.orientation}") - -# Send movement command (ROS frame) -from dimos.msgs.geometry_msgs import Vector3 -drone.move(Vector3(1.0, 0.0, 0.0), duration=2.0) # Move forward 1m/s for 2s - -# Stop when done -drone.stop() -``` - -#### 2. Start in Replay Mode -```python -import os -os.environ['DRONE_CONNECTION'] = 'replay' - -from dimos.robot.drone.drone import Drone - -# Initialize in replay mode -drone = Drone(connection_string='replay') -drone.start() - -# System will replay recorded data from TimedSensorReplay stores -# All functionality works identically to real mode -``` - -### Foxglove Visualization - -The system automatically starts a Foxglove WebSocket server on port 8765: - -1. Open Foxglove Studio -2. Connect to `ws://localhost:8765` -3. Available visualizations: - - 3D view with drone pose and TF tree - - Video stream display - - Depth map visualization - - Pointcloud display - - Telemetry plots (battery, altitude, velocities) - - Status indicators (armed state, GPS fix) - -### LCM Monitoring - -Monitor published messages: -```bash -# View all topics -lcm-spy - -# Monitor specific topic -lcm-echo '/drone/odom' -lcm-echo '/drone/status' -lcm-echo '/drone/telemetry' -``` - -### Environment Variables - -- `DRONE_CONNECTION`: Set to 'replay' for replay mode -- `DRONE_VIDEO_PORT`: Override default video port (5600) -- `DASK_SCHEDULER`: Override Dask scheduler address - ---- - -## Troubleshooting & Known Issues - -### Common Issues and Solutions - -#### 1. No MAVLink Messages Received -**Symptom**: No telemetry data, odom not publishing -**Causes & Solutions**: -- Check UDP port is correct (usually 14550) -- Verify firewall allows UDP traffic -- Check drone is powered on and transmitting -- Try `mavproxy.py --master=udp:0.0.0.0:14550` to test connection - -#### 2. Video Stream Not Working -**Symptom**: No video in Foxglove, video topic empty -**Causes & Solutions**: -- Verify GStreamer is installed: `gst-launch-1.0 --version` -- Check video port (default 5600) -- Test with: `gst-launch-1.0 udpsrc port=5600 ! fakesink` -- Ensure DJI app is not using the video stream - -#### 3. Replay Mode Messages Not Processing -**Symptom**: Replay mode starts but no messages published -**Causes & Solutions**: -- Check recorded data exists in TimedSensorReplay stores -- Verify 'mavpackettype' field exists in recorded messages -- Enable verbose logging: `export PYTHONUNBUFFERED=1` - -#### 4. Coordinate Conversion Issues -**Symptom**: Drone moves in wrong direction -**Causes & Solutions**: -- Never modify NED↔ROS conversion without thorough testing -- Verify with test: `pytest test_drone.py::test_ned_to_ros_coordinate_conversion -v` -- Check signs: East should become negative Y, Down should become negative Z - -#### 5. Integration Test Segfault -**Symptom**: Integration test passes but segfaults during cleanup -**Cause**: Complex interaction between Dask workers, LCM threads, and Python GC -**Solutions**: -- This is a known issue with cleanup, doesn't affect runtime -- Unit tests provide sufficient coverage -- For integration testing, use manual testing with replay mode - -#### 6. Depth Estimation GPU Memory Error -**Symptom**: "CUDA out of memory" errors -**Causes & Solutions**: -- Reduce batch size in Metric3D -- Use CPU mode: device='cpu' in Metric3D init -- Reduce video resolution before depth processing -- Implement frame skipping for depth estimation - -### Performance Tuning - -#### CPU Usage Optimization -```python -# Reduce telemetry update rate -conn.update_telemetry(timeout=0.1) # Increase timeout - -# Skip depth estimation frames -if frame_count % 3 == 0: # Process every 3rd frame - self._process_image(img) -``` - -#### Memory Usage Optimization -```python -# Use smaller video resolution -self.pipeline_str = "... ! video/x-raw,width=1280,height=720 ! ..." - -# Limit message queue sizes -self.mavlink.messages = self.mavlink.messages[-100:] # Keep only last 100 -``` - -#### Network Optimization -```python -# Increase UDP buffer size -import socket -sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) -sock.setsockopt(socket.SOL_SOCKET, socket.SO_RCVBUF, 1024 * 1024) # 1MB buffer -``` - ---- - -## Development History & Fixes - -### Critical Fixes Applied - -#### 1. FakeMsg 'mavpackettype' Field (CRITICAL) -**Problem**: Replay mode failed because FakeMsg.get_type() looked for 'type' field -**Solution**: Changed to look for 'mavpackettype' field -```python -def get_type(self): - return self._dict.get('mavpackettype', '') # Was: .get('type', '') -``` - -#### 2. Video Stream Caching -**Problem**: Multiple calls to get_stream() created multiple subscriptions -**Solution**: Added @functools.cache decorator -```python -@functools.cache -def get_stream(self): - return video_store.stream() -``` - -#### 3. Metric3D Cleanup Check -**Problem**: AttributeError on shutdown if metric3d has no cleanup method -**Solution**: Check for method existence -```python -if self.metric3d and hasattr(self.metric3d, 'cleanup'): - self.metric3d.cleanup() -``` - -#### 4. Video Subscription Pattern -**Problem**: Lambda in subscribe caused memory leaks -**Solution**: Use direct method reference -```python -# Bad: stream.subscribe(lambda frame: self.video.publish(frame)) -# Good: stream.subscribe(self.video.publish) -``` - -#### 5. Connection String Detection -**Problem**: Replay mode not detected properly -**Solution**: Check connection_string == 'replay' explicitly -```python -if connection_string == 'replay': - self.connection = FakeMavlinkConnection('replay') -``` - -### Development Timeline - -1. **Initial Implementation**: Basic MAVLink connection and telemetry -2. **Added Video Streaming**: GStreamer pipeline for DJI video -3. **Coordinate System Fix**: Corrected NED↔ROS conversion -4. **Replay Mode**: Added fake classes for testing -5. **Depth Estimation**: Integrated Metric3D -6. **Bug Fixes**: mavpackettype field, caching, cleanup -7. **Test Suite**: Comprehensive tests for all critical paths -8. **Documentation**: This complete integration guide - -### Git Integration - -All changes are tracked in the `port-skills-agent2` branch: - -```bash -# View changes -git diff main..port-skills-agent2 -- dimos/robot/drone/ - -# Key files modified -dimos/robot/drone/drone.py -dimos/robot/drone/connection_module.py -dimos/robot/drone/camera_module.py -dimos/robot/drone/mavlink_connection.py -dimos/robot/drone/dji_video_stream.py -dimos/robot/drone/test_drone.py -``` - ---- - -## Appendix: Complete Module Interfaces - -### Drone Class Interface -```python -class Drone: - def __init__(self, connection_string='udp:0.0.0.0:14550', video_port=5600) - def start() -> bool - def stop() -> None - def get_odom() -> Optional[PoseStamped] - def get_status() -> Dict[str, Any] - def move(velocity: Vector3, duration: float = 1.0) -> None - def arm() -> None - def disarm() -> None -``` - -### DroneConnectionModule Interface -```python -class DroneConnectionModule(Module): - # LCM Publishers - odom: Publisher[PoseStamped] # /drone/odom - status: Publisher[String] # /drone/status - telemetry: Publisher[String] # /drone/telemetry - video: Publisher[Image] # /drone/video - tf: Publisher[Transform] # /tf - - # LCM Subscribers - movecmd: Subscriber[Dict] # /drone/move_command - - # Methods - def start() -> bool - def stop() -> None - def get_odom() -> Optional[PoseStamped] - def get_status() -> Dict[str, Any] - def move(velocity: Vector3, duration: float) -> None -``` - -### DroneCameraModule Interface -```python -class DroneCameraModule(Module): - # LCM Publishers - depth_publisher: Publisher[Image] # /drone/depth - pointcloud_publisher: Publisher[PointCloud2] # /drone/pointcloud - - # LCM Subscribers - video_input: Subscriber[Image] # /drone/video - - # Methods - def start() -> bool - def stop() -> None - def set_intrinsics(fx, fy, cx, cy) -> None -``` - -### MavlinkConnection Interface -```python -class MavlinkConnection: - def __init__(self, connection_string: str) - def connect() -> bool - def disconnect() -> None - def update_telemetry(timeout: float = 0.1) -> None - def move(velocity: Vector3, duration: float) -> None - def arm() -> None - def disarm() -> None - def odom_stream() -> Observable[PoseStamped] - def status_stream() -> Observable[Dict] - def telemetry_stream() -> Observable[Dict] -``` - ---- - -## Android Setup & DJI SDK - -### Building RosettaDrone APK from Source - -#### Prerequisites - -1. **Android Studio** (latest version) -2. **DJI Mobile SDK Account**: Register at https://developer.dji.com/ -3. **API Keys from DJI Developer Portal** -4. **Android Device** with USB debugging enabled -5. **Git** for cloning repository - -#### Step 1: Clone RosettaDrone Repository - -```bash -git clone https://github.com/RosettaDrone/rosettadrone.git -cd rosettadrone -``` - -#### Step 2: Obtain DJI SDK API Key - -1.
