Project Idea:
Design an autonomous robotic car that intelligently detects and avoids obstacles using ultrasonic sensors. This project introduces basic autonomous navigation principles without the need for remote control or user input. It is perfect for learning sensor-based decision-making, embedded programming, and robotics.
Project Description:
The Object Avoidance Robotic Car is an Arduino-based vehicle that navigates its surroundings by automatically detecting and avoiding obstacles. It uses an ultrasonic distance sensor mounted at the front to measure proximity to nearby objects. When an obstacle is detected within a certain range, the Arduino Uno processes the data and commands the motor driver (L298N) to change direction to avoid a collision. The system runs autonomously, powered by 18650 batteries, and is ideal for beginners interested in robotics and real-time decision-making.
