INTELLIGENT PATH TRACKING AUTONOMOUS ROBOT USING ULTRASONIC SENSORS AND MAGNETOMETER

摘要

Robotics is an emerging field in mechatronics stream. Automation in industrial environment is a prioritised area of interest for many researchers. In largescale industries, transportation of goods from one place to another is often required. The automatic guided vehicles (AGV) are mainly used in such cases. The smartand cost effective solution for moving small and delicate goods in commercial applications is the focus for present study. In order to make the robot smart, robust andcompact, the selection of sensory mechanism with respect to reliability and cost is preferred. The combination of ultrasonic sensors, magnetometer with multiplenumbers of master and slave controllers is unique approach in pursuit of finding the desired outcome. The source and destination of robot is predetermined and theobstacles in the path are randomly arranged. The ultrasonic sensors detect the obstacle and send the data to master control. The magnetometer keeps the track ofdirection in which destination is present. This helps the robot to track down the expected path. The demonstration of experiment is observed and the obtained resultsare being studied.
