The Autonomous Obstacle Avoiding Robot Cart is an innovative robotics and embedded systems project designed to detect obstacles and automatically navigate around them. This project demonstrates the practical implementation of ultrasonic sensing, microcontroller-based control, motor driving and autonomous robotic movement.
Designed as a hands-on robotics project, the system provides students and engineering enthusiasts with an opportunity to understand how sensors and embedded controllers can be integrated to create an intelligent mobile robot.
How Does the Obstacle Avoiding Robot Work?
The robot uses an HC-SR04 ultrasonic sensor to detect obstacles in its path. The ultrasonic sensor continuously measures the distance between the robot and nearby objects.
When an obstacle is detected, the ESP32 microcontroller processes the sensor information and determines the appropriate movement. The control signal is then sent to the L298N motor driver, which controls the DC gear motors.
Based on the detected obstacle, the robot changes its direction and continues moving forward.
