BARRIER AVOIDANCE ROBOT BY FUZZY LOGIC

Abstract

Automated Guided Vehicles have many potential applications in manufacturing, medicine, space and defense. Barrier Avoidance Robot is primary used in embedded systems. The robot is using the fuzzy logic and applied in Arduino Uno microcontroller with ultrasonic sensors. The main scope of the system is to automatically changing the direction of robotic vehicle as required whenever any barrier comes on its ways. The aim of the system is to implement a fuzzy logic Barrier Avoidance Robot. It avoids any static barriers in front of the robot. The fuzzy logic controller uses the sensor data as inputs and drives the motor used in the robot for avoiding the barrier. This system uses three ultrasonic sensors and one output. Sensor detects the presence of any obstacle and sends the signal to microcontroller which changes the direction of the robot. It uses fuzzy logic controller to impart smooth movement of robot while it tries to avoid barrier. The eleven rules of fuzzy set are applied by testing 53 rules set. This system girts with three ultrasonic (HC-SR04) sensors to measure the distance from the barrier.
