RoboGuideX

Autonomous Mobile Robot for Obstacle Avoidance and Traffic Light Detection

📌 Overview

RoboGuideX is an Arduino-based autonomous mobile robot designed to navigate safely in dynamic environments. It integrates multiple sensors for real-time obstacle avoidance and traffic light recognition, enabling smooth and intelligent movement with minimal human intervention.

🔹 Features

✅ Obstacle Detection & Avoidance – Uses an ultrasonic sensor to detect and navigate around obstacles.
✅ Traffic Light Recognition – A TCS230 color sensor identifies red traffic lights and stops accordingly.
✅ Smart Navigation System – Prioritizes stopping at traffic lights while efficiently avoiding obstacles.
✅ DC Motor Control – Uses an L298N motor driver for precise movement control.
✅ Arduino-Based Implementation – Powered by an Arduino Uno for efficient processing.

🛠️ Components & Hardware

• Arduino Uno R3 – Main controller for decision-making.
• HC-SR04 Ultrasonic Sensor – Detects obstacles in the path.
• TCS230 Color Sensor – Recognizes traffic light colors.
• L298N Motor Driver – Controls motor movement.
• DC Motors with Gearbox – Enables movement and navigation.
• SG90 Servo Motor – Adjusts the sensor’s angle for better obstacle detection.
• Power Supply (Batteries) – Provides energy for the system.
• 2-Wheel Robot Chassis – Physical base for the robot.

🔧 System Architecture & Working

1. Obstacle Avoidance:

   • The ultrasonic sensor continuously scans for objects in front of the robot.
   • If an obstacle is detected, the robot decides whether to move left, right, or stop.

2. Traffic Light Detection:

   • The color sensor checks for red lights.
   • If a red signal is detected, the robot halts until it turns green.

3. Movement & Decision Making:

   • The robot prioritizes stopping at red lights over obstacle avoidance.
   • If no traffic signal is detected, it continues moving while avoiding obstacles.
