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.
