Research And Design Of Smart Car Automatic Obstacle Avoidance System Based On Arduino

Automatic obstacle avoidance technology is one of the core technology for smart car, autopilot, intelligent robots. To explore the vehicle’s automatic obstacle avoidance technology,and provide reference hardware control device, the relevant control software and the basic data for the variety of vehicles automatic obstacle avoidance the research of automatic avoidance technology being investigated. In this study, the group purchased and modified three-wheeled car were used to receive information from multi-sensor and variety operating environments, identify obstacle category, design automatic avoidance strategy.Smart car automatic obstacle avoidance technology is based on multi-sensor data fusion, perceived obstacle distribution, distance and other information mainly through the plurality of sensors mounted in their own body, then carry out the corresponding avoidance behavior. With the development of modern information technology, the application of smart car involves not only transportation, military, industrial manufacturing and other industries, but also extends to services and living space exploration and other fields.Firstly, this paper described the research status of smart car automatic obstacle avoidance system at home and abroad, pointed out that focusing on collect information incomplete, and lower efficiency is only part of the automatic obstacle avoidance system defects. According to design the multi sensor collection system with two infrared sensors in front of headstock and two ultrasonic distance sensor on both sides of the body. This system comply with requirements of information collection system and overcome disadvantages mentioned above. Secondly,in this paper, we researched the obstacle avoidance strategy,and divided the obstacles in the environment into 4 basic types, then designed avoidance strategy under the 4 types.Finally, realized the information collection system and automatic obstacle avoidance strategy in use of the Arduino development board.The results of this study designed the automatic obstacle avoidance system of smart car can correctly complete the obstacle avoidance behavior, meet the requirements of the smart car automatic obstacle avoidance, solved some problems in current automatic obstacle avoidance system, achieved the desired target and requirements.
