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: What You Will Need:

  • Arduino Uno
  • Mini Breadboard
  • 3x Servos
  • 2x LED
  • HC-06 Bluetooth Module
  • 680 Resistors
  • Battery at least 5v / 1a
  • Scissors
  • Cardboard

Step 2: Cut Out the Cardboard


Cut out the cardboard for the head by 7cm on each side


Cut out the cardboard for the body by 5cm on each side and also cut out one 3 holes to glue on the servos


Cut out the cardboard for the arms by 2cm Length and 5cm Width

Step 3: Glue in the Cardboard and the Servos Together

Use a hot glue gun to glue on the sides of the cardboard and glue in the 3 servos in the body which we'd cut out earlier on.

Step 4: Wiring & Coding

Please look at the diagram and wire altogether and upload the code

Step 5: Well Done! You Have Finished Making Your "CardBoard the Hero"

As you can see the third box under the body is where all my electronics parts are and glued. This is to make my robot neater and without looking messier with the wiring. You don't have to do this but if you are like me then you are welcome to do this. Moreover, I have powered the robot with an "Rechargeable Solar Emergency Bank".

I also added an elastic for clothes on the head which I can hold and move the robot without moving and breaking the arms or the head.

    I think I might try some different hacks to this amazing project. just wanted to say to the author great job!
    here is my ideas.
    1 paint the robot to look nicer!
    2 make the eyes from the drawing or LED's to a ultrasonic sensor
    and put wheels on it
    so not only can we lake it's arm and head move but it can roll around to!
    3 I might even make like lights the go into the robots chest and gets dark it automatically turns on
    thanks for posting and reading!
    I will be voting for this

    Thanks, your idea is brilliant. I was going to paint the robot in black. I already did an -ible for 2WD Arduino Car and so now I have to link them together.

    Thanks for your comment, as you can see on my instructables page, I already did a robot which moves with legs and I am thinking of bonding together.
