Program a Blast Off! expression (Part A: Sound)

Let’s program a special expression for Astro Bot’s shuttle launch event. This expression will sound like your character is counting down… 3… 2… 1… Blast Off!

From the sensor menu, choose the motion sensor.


Choose any preset expression. We’ll choose Hello, but it won’t matter which one you select because we’ll be customizing it.


Begin by renaming the expression to 3 2 1 Blast Off.


This expression is made up of four sounds. There are already two notes in the Editor. Drag the first sound bar down to note D. Drag the second sound bar up to note D#.


Now, we’ll need to add two more notes. You can do this by clicking on the + button at the bottom. We want the third sound bar on note E and the fourth sound bar on note F#.


Next, we want to adjust the duration in-between each note. This is important for getting the expressions to sound right on the robot, otherwise it’ll either be too fast or too slow. Drag each sound bar to the right to create eight squares of space in-between each notes.


It’s time to customize the note length, intonation, and octave of each sound. Click on the first sound bar (note D). We want to make this sound into a whole note by selecting 1, then change the intonation to rising, and choose the middle octave. Repeat the same process for the second sound bar.


On the third sound bar, we’ll do the same thing as before, but instead of a middle octave, we’ll choose the fourth octave. This will make the third note sound higher. Now we have three notes that will sound like they are climbing! The rising intonation helps add this effect.


We want the last note to sound special by giving it a ‘BLAST OFF’ effect. Click on the sound bar, select 4 for the note length, peaking for the intonation, and the last octave. A 4 represents a quadruple whole note, which means it’s going to sound really long. The peaking intonation will make the note sound like it is climbing up and descending down, like a rollercoaster! The last octave, in the lightest colour, will give the note the highest pitch.


Preview the expression by clicking on the play button. Now, we’ll move on to the robot’s eye patterns!

Program a Blast Off! expression (Part B: Pattern)

It’s time to customize the colour and light patterns on your robot’s eyes. For the start colour let’s choose blue and for the end colour let’s choose red!


We’re going to add on a transformation to give it an exciting effect that goes with our blast off theme. Choose Zig Zag to make the eye patterns appear more dynamic!


Map your expression to a sensor!

To map your 3 2 1 Blast Off expression to a sensor, exit the Expression Editor by clicking on the back button.


The expression is auto-magically saved in your My Expressions library. Drag-and-drop the expression onto the shake event. Now, give your robot a good shake to trigger the expression!
