AUTONOMOUS ACCIDENT AVOIDING SMART ROBOT

Abstract

In today’s rapidly advancing technological world, robotics has become an important field contributing to automation and intelligent systems. The Autonomous Accident Avoiding Smart Robot developed in this project is designed to navigate unknown environments while detecting obstacles and preventing collisions without human intervention. The system uses ultrasonic sensors to continuously measure the distance between the robot and surrounding objects. Based on real-time sensor data, the Arduino microcontroller processes inputs and controls the speed of DC motors through a motor driver circuit. When an obstacle is detected within a critical range, the system automatically reduces speed and applies emergency braking to avoid accidents. An LCD display is used to show real-time information such as distance, movement status, and warning messages, while a buzzer provides audible alerts during emergency conditions. The Arduino platform is selected due to its simplicity, reliability, and ease of programming using the Arduino IDE. The integration of hardware components such as ultrasonic sensors, motor driver, DC gear motors, LCD module, and buzzer ensures smooth and efficient operation. This autonomous robot is capable of real-time decisionmaking, making it suitable for applications in smart transportation and safety systems
