The Smart 4WD Follow Me Robot using Arduino is an advanced and interactive robotics project designed to automatically follow a person or object using ultrasonic and IR sensor technology. Built on a powerful 4WD robotic chassis, this Arduino-based robot combines obstacle detection, motion control, and intelligent tracking into a compact and educational DIY robotics system.
The robot continuously detects nearby objects or a moving target and follows it while maintaining a safe distance. The ultrasonic sensor mounted on an SG90 servo motor scans the surroundings, while dual IR sensors assist in object detection and movement tracking. Powered by rechargeable 18650 lithium cells, the robot provides portable and efficient operation.
This project is ideal for:
- Robotics learning

How the Follow Me Robot Works
The robot uses an ultrasonic sensor mounted on the SG90 servo motor to continuously scan for nearby objects or a person. When an object is detected within a predefined distance range, the Arduino processes the sensor data and commands the motors through the L298N motor driver module.
The 4WD robotic chassis allows smooth movement in all directions, while the IR sensors assist with tracking and navigation. The servo motor rotates the ultrasonic sensor to monitor left and right directions, helping the robot decide movement paths and avoid obstacles while following the target.
The rechargeable 18650 battery pack powers the entire system, making the robot portable and suitable for real-time demonstrations.
