Parts for this stage

  • Connectors
    x4
  • Leg
    x2
  • Battery
    x1

  1. Grab the leg parts

    Grab the leg and connector

  2. Add an Ankle

    Ask a grown-up
    Put the ancle connector into the slot inside the leg, so it is flush on both legs
    Tip: This requires a lot of force to securely get in. Please ask an adult if you struggle

  3. Get the leg parts

    Grab the legs, 2 connector and 2 flat headed screw

  4. Align the joint

    Place the connector into the top of the leg. Ensure the holes align and ensure you have the ramp side of the connector facing down.

  5. Combine the joint

    Combine the two pieces by screwing a flat headed screw into the closest hole to the left of the main center hole

  6. Finish both legs

    Repeat steps 1 to 5 for the other leg, so you have two legs with the connectors screwed in

  7. Fip the bot

    Turn the robot upside down
    Tip: This makes it easier to install the legs

  8. Connect the legs

    Place both legs onto each servo leg straight
    Check: the circular hole is facing the back (Away from the bot's face)

  9. Screw the legs in

    Put a small screw int the center of the leg and screw it in
    Check: the leg should still turn without being pulled out (with gentle force)

  10. Build the feet

    Let's start building the feet, to let our bot wadel

  11. Get the pieces

    Next we need to grab 2 servos, 2 foot shells and 2 foot pads

  12. Pass the wire though

    Pass the servo cable through the hole in the foot shell, with the lip

  13. Insert the servo

    Ask a grown-up
    Push the servo halfway into the foot, ensuring both sides touch one of the blocks inside the foot shell
    Check: the wire does not get sqwished when you push it in
    Tip: this step requires a lot of force to get the servo in correctly

  14. Check your piece is right!

    Check your bot's foot looks like this before fully pushing in

  15. Push the servo fully in

    Ask a grown-up
    Push the servo fully in so the white knob is in the enter of the circular hole

  16. Complete the foot

    Ask a grown-up
    Place the foot cover onto the shell and screw them in
    Check: the screw holes match the holes on the block
    Tip: when printing these peices, there may be left over material blocking the screws. Ask an adult to use an item like a screwdriver or sisors to remove it

  17. Check the feet

    Ensure both feet are completed before continuing

  18. Insert the foot

    Ask a grown-up
    Grab the foot's cabled and pass it through the circular hole in the leg. Then insert the foot into the leg (making sure the cable is moved to the center). Then push
    Check: the wire is not squeezed when inserted
    Tip: the foot should be facing out of the body

  19. Secure the foot

    Use a rounded head screw to combine the foot and leg in the lower hole

  20. Insert cable into the body

    Grab a foot and pass the cable through the back bottom hole of the body

  21. Secure the cables

    Push the cables into the slits on the back of the leg
    Check: make sure to have a bit of wiggle room between the ankle and the wire
    Tip: this ensures the wires are safely secured

  22. Connect the feet servos

    Turn the robot so it face is away from you. Then connect the left leg to S4 and the right leg to S2
    Tip: this ensures the wires are safely secured

  23. 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

  24. Open the code project

    Open the 'Walking Robot' project you made in stage A

  25. Add more angle blocks

    Grab 2 more set angle blocks. Add then to the end of on start
    Tip: Try clicking on the block already in the start block (till it has a yellow highlight), then hold the CTRL or CMD key with the C key.
    Then press V while still holding the CTRL or CMD key

  26. Reset servo angles

    set all the blocks to 90 degrees

  27. Plug in the Micro:bit

    Check: the Robot:bit and battery for the plus (+) and minus (-) signs, then match them

  30. Insert the Robot:Bit

    Grab the Robot:Bit and put it into the body upside down so the microbit is in the face

  31. Add the lid

    Grab the lid and insert it between the raised peices at the back of the body
