Development of a Logistics Autonomous Mobile Robot (EasyBot)

Abstract

This paper presents the development of a logistics autonomous mobile robot by using the line following method which has 3 features of the robot: (1) Line Following; (2) Obstacle Detection; (3) Bluetooth Control. The aim is to replace the need for humans to transportation blood bags for storage in hospitals as an autonomous system design. Infra-Red (IR) sensors are implemented in the robot to detect the path required for the robot to move from point A to B. Ultrasonic sensors are used to detect obstacles. Bluetooth module is used to manually control the robot in case of (1) obstacles cannot be move; (2) relocating the robot. The robot utilizes the Arduino Uno board as the main controller to make the project runs. Finally, the robot's performance is assessed to get it to follow the line accurately and smoothly without drifting away from the line. Experiments are carried out on the best programming, controls, and mechanical design for the best performance of the robots. From results, the robot able to achieve the objectives set to it. This development can give another robot tasking that capable of performing logistic jobs in a designed environment.
