  1. Get started

    Grab the Body, 2 servos and 4 rounded screws.

  2. Screw in the leg servos to the body

    Ask a grown-up
    Grab a servo moter and rounded screw. Then place the servo onto the stands, so that the wire faces the face. Then screw it in. Do the same for the other servo

  3. Attach the sholders

    Use the holes on the sides of the body to screw in the sholder pieces to both sides of the body.
    Check: you are using the long flat headed screws

  4. Insert the hands

    Grab the hand peices and insert them into the holes of the sholder peices on both sides.
    Check: that the rectangle hole (facing to the body) is away from the face
    Tip: you can bend the sholder pieces carefully to insert

  5. Build the brain

    Plug in the Micro:bit into the back slot (facing away from the battery slot) of the Robot:Bit

  6. Connect the servo wires

    Turn the body arround so it faces the other way.
    Then grab the left cable and plug it into pin S1.
    Plug the right cable into pin S3
    Check: that the the wire colours match the pins. EG: red wire to the red pin

  7. Let's calibrate

    Next you are going to use code to get the servos sorted

  8. Go to MakeCode

    Go to a web browser (Not Safari) and enter https://makecode.microbit.org/ into the URL bar at the top of the window.

    Then click the 'New Project' button
    Tip: If you want to access this code on other devices, make sure to press the 'Sign In' button on the top right

  9. Create a new project

    Set the project name as 'Walking Robot', then press the green 'Create' button

  10. Add RobotBit extention

    1) Click on the Extentions draw
    2) Go into the search bar (at the top)
    3) Type in 'RobotBit'
    4) Press enter
    5) Click the first one

  11. Plug in the Micro:bit

    Grab the USB cable and plug it into the Micro:bit and your device

  12. Download the code

    Click the download button on the bottom left of your screen. Then follow the instructions on the screen to pair your MicroBit

  13. Swap the USB connection

    Unplug the USB cable from your Micro:Bit and plug it into the front of the Robot:Bit. Finally flip the switch so the light turns from green to red.
    Check: if done right, you should hear the servos move. If the wiring is correct but you hear no sound, feel free to continue

Stage A Done!

Building Stage B

For grown-ups

Steps marked Ask a grown-up need an adult's hands or eyes

In this stage

Step 2 requires screwing in the servo moters into the body. Which is very tight and is challanging. Please help your child with this step
