Abstract: This paper describes a smart cart robot that can move and   avoid obstacles on its own. The robot is built using an ultrasonic sensor to detect obstacles, DC motors for movement, a Bluetooth module for wireless control, and a motor driver to manage the motors. An Arduino UNO board is used to process all the information and control the robot, while the chassis and wheels form the robot’s body. The Arduino IDE is used for programming the robot. The ultrasonic sensor helps the robot "see" and avoid obstacles, while the Bluetooth module allows users to control it remotely. This smart cart robot can be used in various applications like automated shopping carts or warehouse automation, showing how different hardware and software components can work together to create intelligent machines.

Keywords: Autonomous Navigation, Obstacle Detection, Path Planning, Distance Avoidance, Ultrasonic Sensing Real-time Data.
