DIY - Motion Sensor Based Robot Head Movement Kit - MPU6050, Arduino Nano and SG90 Servo Motor

Project Overview:

Create your own interactive robot head that mimics your head movements! This DIY kit uses the MPU6050 motion sensor to detect tilt and rotation, and translates this data to control an SG90 Servo Motor, simulating head movement. It’s a great introduction to motion sensing, servo control, and microcontroller programming with the Arduino Nano.

What You’ll Build:

A robotic setup that moves its "head" in response to the orientation of a sensor – as you tilt the MPU6050 module, the servo motor reacts in real-time, moving the robot's head accordingly.

Learning Outcomes:

• Understand the principles of motion sensing with accelerometers and gyroscopes

• Learn how to read and interpret data from the MPU6050 sensor

• Control servo motors using PWM (Pulse Width Modulation)

• Gain hands-on experience with Arduino Nano coding and circuit integration

• Develop skills in prototyping and DIY robotic.

How It Works:

1. The MPU6050 detects movement along X, Y, and Z axes (acceleration + gyroscope).

2. This sensor data is processed by the Arduino Nano, which calculates the angle of tilt.

3. The calculated tilt angle is mapped to servo rotation (0° to 180°).

4. The SG90 servo motor moves accordingly, rotating the robot head to follow your movement.

Components Required

To get started, you'll need the following components:

1. Arduino Nano - 1

2. MPU6050 Accelerometer & Gyroscope Module - 1

3. SG90 Servo Motor - 1

4. 400 point Breadboard - 1

5. Jumper Wires Male to Male - 1

6. Jumper Wires Male to Female - 1

7. Breadboard Power module - 1

Assembly Instructions:

1. Mount the MPU6050 on a small headband or hold it in your hand.

2. Assemble the servo motor into the robot head frame.

3. Connect all components as per the circuit diagram.

4. Upload the Arduino code using the Arduino IDE.

5. Power the Arduino Nano and move the MPU6050 – watch the servo motor respond!

Optional Enhancements:

• Add a second servo for pan/tilt movement (2-axis).
