Hello everyone, I am Merve!

We're going to make a robot walking with a Coca-cola tin this week. *_*

Let’s start !


Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Required Materials:

  • 6V 250 RPM motor (x2)
  • Two 9V batteries (x2)
  • Two 9V battery clip
  • Coca-Cola tin (x1)
  • Switch (x1)
  • Materials for decoration
  • Solder
  • Adhesive

Step 2: Construction of the Project

We cut the yellow protrusions underneath the motors in the picture.

Step 3: Siliconized Motors

Then we stick the motors with silicone like in the picture. Here is the part that needs attention; first apply some silicone on the white part and stick the white part of the other motor here, wait a long time to make sure it sticks. Make sure that the silicone does not touch the yellow parts of the motor!

Step 4: Siliconized Batteries to the Motors

Our motors stick together! Now we stick the batteries to the motors.

Step 5: Circuit Design

Now we can constitute the circuit. Solder the cable in the picture to the cross-ends of the motors, then silicoze.

We continue to constitute a circuit like the picture.


The circuit is over! Let's test the robot by opening and closing the switch. If the robot is not running, it means that you made a mistake in the circuit constitute. (if your batteries are full :P) Check connections again.

Step 6: Design

We came to the most fun part of our project! You can do the design part as you like.

We cut the Coca-Cola tin like the picture. We will use the rest for the robot's head.


I cut a small rectangular place in the Coca Cola tin and paste the switch to that part as in the picture. We then place the Coca Cola tin on top of the motors as in the picture and thoroughly siliconize the motors.

To make the robot’s head, we stick the rest of the Coca Cola tin to the top of the robot. I used a pipette for the robot’s arms and I used the eyes that the moving eyes. You can decorate your robot with the decorations you want! The robot is ready! Let's see how you work and walk! :)


I expect your comments for the project. You can comment your questions or contact me.^_^

    yayyyy! I am really happy to hear that! <3


    Question 1 year ago

    Are you only counting on vibrations to move the whole ? I think a single motor would be enough.

    If the robot had just a motor, the robot would not walk :D I meant the motors are the robot's legs. You can ask any question about this project! ^_^

    Yes, and the batteries are the feet, with only one foot it cannot walk can't it ? But one battery could be enough if motors are connected in parallel. My question concerned the concept, if it's based on vibrations, one motor can fit, thus one battery. Missing leg and foot can be made of cardboard or whatever.

    hmmmm I understood. Yes motors are connected in parallel. I could have made this robot with only one battery and one motor and could have made other leg and feet of cardboard as you said. Beside i would have used less materials. I really thank you for that good idea! ^_^

    Çok değişik bir teknik,ilk defa motor millerinin birbirine akuple olduğu bir proje görüyorum.Tek eleştiri yapacağım kısım;kabloların birbirine bağlandığı yerlere makaron geçirseydin çok daha iyi olurdu.Malum, bant titreşim ile veya sıcaktan yerinden düşebilir ve açıkta kalan uçlar metal kutuya temas ederek istenmeyen kısa devreler oluşabilir.Tebrikler.

    Bu konuda haklısınız, makaron kullanmak en doğrusu olurdu. Buna dikkat edeceğim! Yorumunuz için teşekkürler ^_^


    Question 1 year ago on Step 1

    What is the source for the motors? I am hosting a robotics summer camp this month and this is a perfect project for my upper elementary session.!
