What is the LEGO WeDo 2.0?

The LEGO WeDo 2.0 combines LEGO building elements with block-based coding to make STEAM learning fun and accessible. Here are the key parts of the WeDo kit:

LEGO WeDo Smart Hub: This houses the batteries for the WeDo and is the part that will connect via Bluetooth to your device. When the light is flashing, it is turned on and searching for a device to pair with. When the light is solid, it has connected.

LEGO WeDo Medium Motor: This is the motor that will power your robot. This motor can only turn clockwise and counter clockwise, so the range of motion of a WeDo kit is limited by the actions of this motor.

Tilt Sensor: This sensor can detect 6 different positions as it is turned, like a joystick! (it can sense this way, that way, up, down, no tilt, any tilt)

Motion Sensor: The motion sensor can detect objects, very roughly, up to 15 cm away, depending on the shape of the object and other properties (reflection, colour, etc.). It is sometimes called a distance sensor.

LEGO Bricks: A variety of LEGO building elements and an organization chart for ease of finding the piece(s) that you need.

Before using the WeDo 2.0, make sure you install the free app on a device with Bluetooth capabilities.

Below you will also find instructions for connecting your tablet to your LEGO WeDo:

1) Open the LEGO Education WeDo 2.0 Programming App and start a new project.

2) In the top right corner of the WeDo coding screen there is a blue button with a picture of the Smart Hub on it. If you can't see this image, close any open menus (such as the light bulb, or camera) by tapping on their icon.

3) Press the blue Smart Hub button to open the Smart Hub menu.

4) With the menu open on your tablet, you will now press the green button on your WeDo Smart Hub, as indicated in the picture. When the Smart Hub is on, the light on it will flash and it will beep. If the Smart Hub won't turn on, it probably needs new batteries! Each Smart Hub takes 2 AA batteries.

5) Once the Smart Hub is flashing, return to the iPad. On the right side menu, the name of your Smart Hub should appear. If it does not, use the refresh button at the bottom of the screen.

6) When a Smart Hub appears on the list, tap on it to connect. When you have connected to a Smart Hub, the light on the Smart Hub will remain on as a solid colour and the beeping will stop.

7) When you're done playing, turn off the Smart Hub by pressing and holding the green button.

Activity 1: Dancing Robot

This activity introduces building and coding with the LEGO WeDo 2.0. It will inspire participants to think in new and creative ways, boosts fine motor development, and encourages risk taking and experimentation.

For this activity, you will need:

x 1 x WeDo 2.0 kit x 1 x Dancing Robot building instructions x 1 x Device with WeDo 2.0 app installed x 1 x Head template for your robot x Crayons or pencil crayons x Tape

Start by building your dancing robot following the step by step instructional handout included in the kit. Pay close attention to the size of bricks and axles you are to use. The axle will include a blue number in a circle to let you know the length in LEGO measurements. For example, the axle in this image will be the same length as a size 10 LEGO brick.

When you are finished your build, it is time to choose and decorate a head for your robot! Attach with tape to the upright axle.

Ready to make your robot move, dance, and sing? Click on the LEGO WeDo 2.0 app on your device to open the block based coding program.

On the home page, click on the + sign under "My projects" to open a new project.

This will bring you to a whitespace with coding blocks along the bottom. Take a moment to explore the coding blocks. What do the different colours mean? What do you think each of the blocks will do? To add a block to your code, click and drag the block onto the whitespace. If you are using a touch-screen device, touch and drag the block. For the code to work, it must be attached to the starting play button. Here are some examples of coding blocks that you can add to your code. Which ones would you choose to make your robot dance?

Here is an example of a code that will make your robot dance, and what each block means.

1. "Go" 2. "Motor Turn Counter Clockwise". Tap it to change to "Motor Turn Clockwise" 3. "Motor Run For _15__ seconds" 4. "Motor stop" 5. a. "Pause" (or "wait for")

b. "Microphone" The robot will listen for a sound and when it hears the sound, it will continue with the next block of code. 6. "Change Colour". Change the number to change the colour. 7. "Play Sound". Sound is played through the iPad. Change the number to change the sound.

How is the following code similar, and how is it different? What sound did it play and what colour did it change?

Remember to connect the LEGO WeDo 2.0 to your device before playing the code by clicking on the picture of the Smarthub and the Bluetooth symbol.

Now it's time to show off your dancing robot! Congratulations! Variations:

x Make your robot change colours as it dances (a second line of code just for colours) x Move faster and slower depending on the song you hear x Adjust your dancer's appearance (add different blocks to the dancer's body) x Create a face using the remaining LEGO x Add in the motion sensor and try coding your robot so it moves when your hand is in

front of it
