Background

I am a software developer. I have read a lot about the field of robotics before I decided to enter into this interesting world.

A question came to mind: why not make a robot to do some cool stuff? Then I have already started to learn how to program electrical circuits and annexed to this talent making paper craft models.

A moving robot works to calculate ambient objects and gives an alarm when it exceeds a certain limit and can be controlled by the computer.

Step 1: (The IDEA)

I used a paper craft model from Paper-replika. Download the paper model from here: http://paper-replika.com/index.php?option=com_content&task=view&id=466&Itemid=30

And when I place the electronics parts inside the model and made the maquette alive.

*I fold the model head and then I put an ultrasonic sensor inside, instead of the robot's eyes.

Step 2: Testing the Sensors

Testing the sensors after placing it inside the head.

I used an Arduino Uno and an ultrasonic sensor to make the robot measure the distance.

For example, if the object is 10 cm away from the sensor, and the speed of the sound is 340 m/s or 0.034 cm/µs the sound wave will need to travel about 294 u seconds. But what you will get from the Echo pin will be double that number because the sound wave needs to travel forward and bounce backward. So in order to get the distance in cm we need to multiply the received travel time value from the echo pin by 0.034 and divide it by 2.

Here is the full tutorial on how to use ultrasonic sensors: https://www.arduino.cc/en/Tutorial/Ping

Step 3: Body Mechanism

To make the robot more realistic, I put three servo motors inside the body to control the movement of the head and arms.

Have a look at this servo motor and what it's able to do: https://www.arduino.cc/en/Reference/Servo

Step 4: Robot Arms

The robot is still missing two arms. So I installed the structure of the arm paper model as shown then I placed the servo gear inside it, that way you can easily control them.

EXPANDED TECHNICAL DETAILS

Kinetic Paper Engineering

This project brings the lovable repair bot "Burn-E" to life using a unique blend of paper-crafting and Arduino-driven robotics.

• Lightweight Servo Linkage: The Arduino manages small SG90 micro servos hidden within the paper structure. The firmware coordinates the movement of the "welding arm" and the "head" to replicate the character's signature nervous animations.
• Acoustic Interaction Hub: Includes a small piezo buzzer; the Arduino plays 8-bit sequences that simulate the "Binary-Beep" language of the movie robot during different states of repair/failure.

Interactive Modes

• Motion-Triggered Repair: Uses a small vibration or tilt sensor; when the robot is bumped, the Arduino initiates a "Panic Dance" animation, enhancing the toy's personality and interactivity.
