What is the Otto Robot?
The Otto Robot is an open-source, 3D-printed robot that uses an Arduino Nano to control its movement and behavior. Designed as an educational robotics kit, Otto helps beginners learn about Arduino programming, sensors, and servos while having fun.
💡 Inspired by the original Otto DIY project, which you can find on Instructables:

How Otto Robot Works
Otto uses servo motors for movement, an ultrasonic sensor for obstacle detection, and a buzzer for sound effects. When powered on, Otto can:
✔ Walk & Dance – Moves its legs using servo motors.
✔ Avoid Obstacles – Uses an ultrasonic sensor to detect objects and change direction.
✔ Make Sounds – Plays beeps or melodies using a buzzer.
✔ Customizable – Modify the 3D-printed design, code, and features!
Components Required
To build your Otto Robot, you’ll need:
🔹 Arduino Nano – The brain of the robot.
🔹 Arduino Nano Expansion Board – For easy wiring.
🔹 4 x Servo Motors (SG90) – Controls the robot’s legs.
🔹 Ultrasonic Sensor (HC-SR04) – Detects obstacles.
🔹 Buzzer – Optional for adding sound effects.
🔹 3D-Printed Body Parts – Or you can use a DIY cardboard alternative.
🔹 Battery Pack (Li-ion or AA Batteries) – Powers the robot.
Step-by-Step Guide to Building Otto
Step 1: 3D Print or Assemble the Robot’s Body
-
Download Otto’s 3D-printed files (or use a DIY alternative like cardboard).
-
Print the body, head, and leg parts using a 3D printer.
Step 2: Connect the Electronics
-
Plug the Arduino Nano into the Expansion Board.
-
Attach the servo motors to Otto’s legs and body.
-
Connect the ultrasonic sensor to detect obstacles.
-
Wire up the buzzer (optional) for sound effects.
Step 3: Upload the Code
-
Install Arduino IDE on your computer.
-
Download Otto’s open-source code from GitHub:
👉 🔗 GitHub Repository -
Upload the program to the Arduino Nano.
Step 4: Power Up & Test!
-
Insert the batteries and switch on the robot.
-
Watch Otto walk, dance, and avoid obstacles!
Customizing Your Otto Robot
Want to make Otto even cooler? Try these modifications:
🔹 Add Bluetooth – Control Otto via a smartphone app.
🔹 Voice Control – Use a microphone module to make Otto respond to voice commands.
🔹 LED Eyes – Install LEDs to make Otto’s face expressive.
🔹 Different Dance Moves – Modify the Arduino code to add new movements!
Conclusion
Building an Arduino Otto Robot is a great way to learn electronics, coding, and robotics. Whether you’re a beginner or an advanced maker, Otto is a fun and engaging project that can be easily customized.
