• Sensor Fusion: Flight control systems typically include sensors such as gyroscopes, accelerometers, and magnetometers to obtain the drone’s attitude, speed, and position information. Through sensor fusion algorithms (such as Kalman filtering), data from multiple sensors is integrated to improve flight accuracy.

• Attitude Control: Based on sensor data, the flight control system calculates the drone’s attitude and adjusts motor speeds through a PID controller to maintain stable flight.

• Navigation and Positioning: By combining GPS or other positioning systems, the flight control system can achieve autonomous navigation, plan flight paths, and ensure the drone flies along a preset route.

• Wireless Communication: Communication between the flight control system and the ground station is crucial for sending remote control commands, receiving flight status data, and enabling remote control and real-time monitoring.

• Fault Detection and Safety Mechanisms: The flight control system should have fault detection capabilities to respond promptly to anomalies, such as switching to backup mode or emergency landing, ensuring flight safety.

6. AI Car Based on ESP32-CAM:ESP32-CAM is a microcontroller module that integrates Wi-Fi and Bluetooth functions, and it is particularly equipped with a camera interface, making it an ideal choice for building smart robots. This project will demonstrate how to use the ESP32-CAM module to build a simple AI robot. This robot can stream video in real-time to an Android device and perform AI task processing on the Android device.7. Embedded Vehicle Terminal System Qt:

The QT vehicle system is a comprehensive in-vehicle information system developed based on QT6, integrating various functions such as music playback, weather forecasting, map navigation, and video playback.

• Music Function: The music module in the QT6 vehicle system allows users to play, pause, stop, and control volume. It may support various audio formats and features playlist management, search, and random playback. Through the integrated music library interface, it can easily interact with external music services or locally stored music.

• Weather Function: Utilizing web APIs, the QT6 vehicle system can obtain and display real-time weather information, including temperature, humidity, wind speed, and weather conditions. The user interface is designed to be intuitive, allowing drivers to quickly understand current and future weather conditions while driving, ensuring driving safety.

• Map Navigation: The QT6 vehicle map function may use popular open-source map libraries like OpenStreetMap or commercial map services, supporting route planning, positioning, and real-time traffic information display. Users can input destinations via touch or voice commands, and the system will automatically calculate the best route and navigate. Additionally, the map interface design focuses on driver-friendliness, with clear icons and easy-to-understand directional indications to ensure concentration while driving.

• Video Playback: Considering driving safety, the in-vehicle video playback function may only be available when parked or not driving. QT6 supports decoding various video formats, providing full-screen and small window modes, allowing users to watch movies, video tutorials, and other entertainment content while waiting or resting.

• From a development perspective, QT6 provides a complete set of development tools, including the Qt Creator IDE, QML (Qt Modeling Language) for declarative programming, and a rich set of Qt libraries, such as Qt Widgets and Qt Quick, enabling developers to build beautiful and efficient user interfaces. Furthermore, QT6 enhances support for multiple platforms, including Linux, Windows, Android, and iOS, allowing the vehicle system to seamlessly adapt to different platforms.
