🎮 Usage

Web Dashboard Control

  1. Navigate to http://localhost:3000 for the main control interface
  2. Monitor Status - Real-time robot position, battery, and sensor data
  3. Interactive Navigation - Click anywhere on the map to set navigation goals
  4. Control Modes - Switch between Manual/Auto/Emergency modes
  5. Task Management - View active tasks and use "Stop All Tasks" for emergency stop
  6. Manual Control - Use directional pad for direct robot control
  7. Real-time Updates - Live WebSocket connection for instant feedback

API Control Examples

# System Health Check
curl http://localhost:8080/api/health

# Get comprehensive robot status
curl http://localhost:8080/api/status | jq

# Create navigation task to specific coordinates
curl -X POST http://localhost:8080/api/navigation/goal \
  -H "Content-Type: application/json" \
  -d '{"x": 5.0, "y": 3.0, "theta": 0.0, "timeout": 30.0}'

# Stop all active tasks immediately
curl -X DELETE http://localhost:8080/api/tasks/all

# Emergency stop (immediate halt)
curl -X POST http://localhost:8080/api/emergency/stop

# Get current navigation status
curl http://localhost:8080/api/navigation/status

# Manual movement commands
curl -X POST http://localhost:8080/api/control/move \
  -H "Content-Type: application/json" \
  -d '{"command": "forward", "speed": 0.5, "duration": 2.0}'

# Change system operating mode
curl -X POST http://localhost:8080/api/lifecycle/activate

Test Dashboard & Reports

Access comprehensive test reports and coverage analysis at: http://localhost:3001

The test dashboard provides:

  • Live Test Results - Real-time test execution status
  • Coverage Reports - Visual coverage analysis with line-by-line details
  • Performance Metrics - Execution time and memory usage statistics
  • Static Analysis - Code quality issues and recommendations
  • Test History - Historical test trends and regression analysis

Automated Testing Workflow

# Every docker-compose build automatically:
# 1. Compiles all C++ code with comprehensive warnings
# 2. Runs complete Google Test suite
# 3. Generates coverage reports with LCOV
# 4. Performs static analysis with CPPCheck
# 5. Copies all reports to accessible volumes
# 6. Serves reports via web interface on port 3001

# Manual test execution
docker-compose run --rm agv-system bash -c "cd /workspace && ./scripts/docker_test_runner.sh"

# Build with comprehensive reporting
./scripts/build_with_reports.sh

🔧 Troubleshooting

Common Issues

❌ "Connection refused" errors

# Check if containers are running
docker-compose ps

# Restart services
docker-compose restart

❌ Web dashboard not loading

# Check UI server status
curl http://localhost:3001

# Restart UI server
docker-compose restart

❌ Tasks not executing

# Check AGV system logs
docker-compose logs agv-system

# Verify API connectivity
curl http://localhost:8080/status

❌ Stop All Tasks not working
