The research and design of autonomous walking robot based on ultrasonic and wireless control system

摘要

In an uncertain environment intelligent robots can get the direction of the object and calculate the best path to the object based on the collected environment information or the navigation information given by the object. Global path planning is the key technology to achieve autonomous navigation. In this system, I use multiple ultrasonic information fusion, detect environmental information around the vehicle system ,use ARM7 embedded processor as the system core, process the information collected by the system, realize obstacle avoidance capabilities, and use ZigBee wireless control module. By this way PC can achieve the navigation control to the vehicle. In the process of the global path planning, the ant colony algorithm is the key of the system, I improve it based on the idea of artificial potential field algorithm and avoid local optimal solution. Test results proved the feasibility and rationality of the system design.
