Autonomous Omnidirectional Mobile Robot for Indoor Navigation

Abstract

The rapid advancements in robotics and artificial intelligence have paved the way for the development of autonomous systems with remarkable capabilities. This research presents the design and development of an autonomous omnidirectional mobile robot. Our primary objective is to create a versatile and agile robot capable of navigating complex environments efficiently and autonomously. The robot's design features a mechanical base equipped with four omnidirectional Mecanum wheels, four DC motors, a motor driver, a single-board computer-based control system, an artificial intelligence visual sensing module, an infrared tracking module, an ultrasonic sensor, and a rechargeable solar-powered battery. The Mecanum drive system utilizes wheels with rollers obliquely attached to their circumference, positioned at 45° to the wheel plane and 45° to the axle line. This unique configuration enables the robot to move seamlessly in various directions, including forward, backward, sideways, diagonally, and rotation. Moreover, the robot incorporates a fully automated autonomous driving system capable of environment sensing, obstacle detection, and independent operation without human intervention. This project not only contributes to the development of advanced robotics but also serves as a valuable educational tool for students. It provides practical experience in mechatronics, artificial intelligence, and smart robotic systems, thereby enhancing their hands-on skills and preparing them for the dynamic engineering landscape.
