Abstract: The rapid advancement in robotics has led to the development of intelligent systems capable of autonomous navigation. This project presents the design and implementation of an Obstacle Avoiding Robot Car, utilizing an Arduino microcontroller, an ultrasonic sensor, and a servo motor for real-time obstacle detection and avoidance. The robot autonomously navigates its environment by detecting obstacles in its path and making decisions on the optimal route to avoid collisions. This project is a step towards developing more complex autonomous systems that can operate in dynamic environments with minimal human intervention.
Introduction:
The development of autonomous robotic systems has gained significant attention in recent years due to their potential applications in various fields, including industrial automation, exploration, and personal assistance. An Obstacle Avoiding Robot is a fundamental example of such a system, where the robot is designed to navigate an environment without human guidance, avoiding any obstacles in its path.
The importance of obstacle avoidance in robotics cannot be overstated, as it ensures the robot's ability to operate in unpredictable environments. This project utilizes an Arduino microcontroller, which is known for its ease of use and flexibility, making it an ideal choice for prototyping robotic systems. The integration of an ultrasonic sensor allows the robot to detect obstacles by measuring the distance to objects, while a servo motor enables the sensor to scan the surrounding area.
This project builds upon basic robotics principles, combining them with modern microcontroller technology to create a simple yet effective autonomous system. The use of a motor driver shield further enhances the robot's capabilities by providing precise control over the movement of the DC motors, allowing for smooth and responsive navigation.
The Obstacle Avoiding Robot Car project is not only an educational tool but also a foundation for more advanced robotic systems that could be used in various applications. This project aims to demonstrate the feasibility of creating an autonomous navigation system that is both cost-effective and efficient, contributing to the ongoing development of intelligent robotic systems.
