The purpose of this thesis is to develop an automatic guide vehicle (AGV) that based on using different waves distance measurement method. And it can also actively following the user’s movement; whenever the user goes, it will automatically follow the user. The car can also maintain a certain distance to the user during the following activity.
In order to achieve the feature of “auto-following”, utilization the different wave movement speed in the air between the “radio” and “ultrasonic” waves are used in this paper. A distance measurement system is developed here. When using the system, a set of projector is set up in the user’s waist, and a set of receivers are set in the car; use the transmitter and the receivers to determine and calculate the relative position and distance between the user and the car.
Microchip PIC 18F452 is used as the control core, utilize the ultrasonic receivers set on both right and left sides of the car, determinate the relative positions between the user and the car; furthermore, with additional infrared ray sensors to determinate the distance with the barriers. “Fuzzy thinking” method is then used to control the motor, and achieving the function of automatic following and barriers dodging.
This research adapted a self-made distance measurement system, successes developed an automatic guide vehicle that can automatically following the user, and maintain a certain distance; also includes the feature of barriers dodging.
