Designing Navigation and Obstacle Avoidance System Combining Smart Car And Quadrotor Aircraft

The navigation and obstacle avoidance system combining smart car and quadrotor aircraft takes MK60FX512VLQ15 microcontroller as the intelligent car control unit and STM32F767IGT as the image processing unit of flying platform. This system first collects image information through the infrared camera equipped in the quadrotor aircraft, and sends it to the processing unit for extraction and processing. Then this system transmits the information to the smart car master through the NRF2.4G wireless module and integrates it with the smart car's own gyroscope data. In this way, the system is able to tell the relative angle of the smart car with the target according to the result, obtain the operating environment and state of the car body through its own ultrasonic ranging, encoder and other modules, and adjust the car's speed and direction so as to avoid obstacles. The system is smooth in operation, flexible in adjusting speed and direction, and is fully capable of avoiding obstacles. (paper)
