The innovation of a maze solving robot equipped with an acrylic sheet presents a pioneering solution to enhance the durability and precision of robotic navigation in complex environments. This revolutionary concept combines cutting edge technology, including an Arduino Nano controller, ultrasonic sensor for wall detection, and N20 motors for locomotion. The primary objective of this innovation is to safeguard the robot against potential damage while maintaining the accuracy of distance measurement. To achieve this, an acrylic sheet is strategically affixed atop the robot's chassis. This acrylic shield serves a dual purpose: it acts as a protective barrier, preventing collisions with maze walls, and simultaneously eliminates the risk of erroneous distance readings caused by sensor interference with the maze structure. Crucially, this shielding solution ensures that the distance range between the ultrasonic sensor and the maze walls remains unaffected. The ultrasonic sensor plays a pivotal role in the robot's navigation by emitting ultrasonic waves and measuring the time taken for their reflection. By maintaining the sensor's accuracy and unhindered functionality, our innovation preserves the robot's ability to navigate and make informed decisions based on its surroundings. In essence, this project represents a harmonious fusion of technological advancement and practical problem solving. It addresses the critical issue of robotic damage prevention without compromising the robot's core functionality. By combining meticulous engineering with innovative thinking, we have developed a maze solving robot that can navigate intricate mazes with precision, confidence, and durability, opening up new possibilities for applications in various industries, from automated logistics to educational robotics. This abstract encapsulates the essence of our groundbreaking innovation, demonstrating its potential to revolutionize the field of robotic navigation and inspire further advancements in the realm of autonomous machines.
