Jun 27



This project is suitable for kids aged 10 to 15 years old. It introduces basic concepts of robotics, electronics, and programming in a fun and engaging way. Younger children might need some adult supervision and assistance, especially with using tools and handling electronic components.

Getting Started with the DIY Kit

Materials You Will Need

Before you start building, gather the following materials:

- A robot chassis (the body of your robot)

- Two DC motors with wheels

- A motor driver board (like L298N)

- An Arduino microcontroller

- Ultrasonic distance sensors (like HC-SR04) or infrared sensors

- A battery pack

- Jumper wires

Assembling Your Robot

Assembling a human following robot involves attaching the motors and wheels to the chassis, connecting the motor driver and Arduino microcontroller, and fixing the sensors in place. Ensure all connections are secure and power off the components while making connections. Finally, upload a simple Arduino program to control the motors based on the sensor inputs.

Enhancing the Learning Experience & Experiment with Sensor Placement

Building a human following robot is just the beginning. Here are some ideas to make the experience even more exciting:

Try placing the sensors at different heights and angles to see how it affects the robot's ability to detect and follow a human. This can help you understand the importance of sensor positioning in robotics.

Add More Features

Enhance your robot by adding more sensors or components. For example, you can add more ultrasonic sensors to improve detection accuracy or a camera module for advanced image processing and following.


Building a human following robot is a fun and educational project that introduces kids to the exciting world of robotics. By following these simple steps, you can create a smart robot that can navigate its way and follow a human all by itself. So, gather your materials, follow the instructions, and enjoy the thrill of watching your very own robot in action!

Remember, the journey of building and learning is just as important as the final product. Happy building!


What is a human following robot?

A: A human following robot is an autonomous robot that can detect and follow a human using sensors, typically ultrasonic or infrared, to measure the distance to the person.

 Do I need to know programming to build this robot?

A: Basic knowledge of programming is helpful, but the provided code is simple and easy to understand. You can also find many tutorials online.

What should I do if my robot isn't following correctly?

A: Check the sensor connections and ensure they are correctly placed. Make sure the sensors are calibrated properly and adjust the sensitivity in the code if needed.

Can I use different sensors?

A: Yes, you can experiment with different types of sensors like infrared sensors, laser distance sensors, or even cameras for advanced image processing.

What skills will I learn from this project?

A: You'll learn basic robotics, electronics, and programming skills. You'll also gain experience in problem-solving and critical thinking as you troubleshoot and optimize your robot.
