The Research and Design of Autonomous Walking Robot Based on Ultrasonic and Wireless Control System

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. The design system which described in this paper uses multiple ultrasonic information fusion to detect environmental information around the vehicle system, employs ARM7 embedded processor as the system core to processes the above collected information to realizes obstacle avoidance capabilities. Through ZigBee wireless control module, 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, then 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.
