Roborider Robotics Car

The Multi-Functional Smart Robotic Car Using Arduino is an intelligent robotics project that combines three advanced control methods into a single vehicle: Obstacle Avoidance, Bluetooth Control, and Voice Control. Built using an Arduino microcontroller, ultrasonic sensor, Bluetooth module, motor driver, and DC motors, the car can operate both autonomously and under user control. In Obstacle Avoidance Mode, the ultrasonic sensor continuously measures the distance to objects ahead. When an obstacle is detected within a predefined range, the Arduino automatically stops the car or changes its direction, allowing it to navigate safely without human intervention. In Bluetooth Control Mode, users can manually control the car through a smartphone application. Commands such as forward, backward, left, right, and stop are transmitted via the Bluetooth module (HC-05/HC-06), enabling wireless operation. In Voice Control Mode, the car responds to spoken commands received through a mobile application connected via Bluetooth. The Arduino interprets these commands and controls the motors accordingly, providing a hands-free and interactive driving experience. Objectives To develop a smart robotic vehicle with multiple control methods. To understand the practical applications of Arduino programming, sensors, and wireless communication. To enhance knowledge of robotics, automation, and embedded systems.
