Guest post: Airblock hovercraft ‘dance move’ project

small

This is a guest post by Airblock user, software developer and Code Club New Zealand volunteer and maker Ben Chartrand, originally posted on his blog LIFT.CODE.PLAY. 

I recently received Makeblock Airblock. It’s a drone / hovercraft you can program using a Scratch-like language and I’ve been keen to create my first project. Took me a while to learn a few key things but I’ve now got my hovercraft doing a ‘dance move’ (I wanted it to move a certain way).

Requirements

Creating the Code

  • Open the Makeblock app
  • Pair your Airblock to your tablet
  • Click My Projects
  • Click the Add + icon and select Land Mode
  • Click the Design tab
  • Add the following from the Move menu options:
    • Power
    • The two direction palettes
  • In Custom add a button
  • Touch the button and change the name to Dance

So far you should have something that looks like this. You can arrange it however you like.

Once you have that setup click the button again and select Code. You will see two blocks. Enter the code similar to what you see below.

About the code

A few key things to notice in the picture above:

  1. We used the Set suspension block. This is important because this defines the power the Airblock will use to go back and forward. I entered huge numbers meaning it will go fast!
  2. We also used a wait block. You need to give your Airblock time to complete an operation before jumping into the next one
  3. The button released event was used. That means it will only take off once you take your finger off the button. If you hold down your finger but don’t release the button, nothing will happen

Let’s Play!

Once you’re done, click the PLAY button. It should look like the following.

To make it go, flick on the power and press DANCE

Here’s a video of my Airblock in action.

Note that the control items we added were there purely to give us manual control, incase we needed it. I used it because, when testing, sometimes I was too lazy to get up, bring my drone back to the start position.
