Creating Your First Expression


What are custom expressions?

Aside from setting expressions, you can also create your own custom expressions. Expressions are made up of four musical notes. Use your imagination to design characters with funky, creative, out-of-the-box personalities! Start by asking yourself: what special character do I want to bring to life?

Custom Costume

Starting with a set expression

First, click on any expression in the menu provided. You’ll see a pencil icon pop-up. Select it to enter the expression editor. Here is where you can customize your robot’s eye colour, experiment with light patterns, and make your own expressions by adjusting notes, intonations, octaves, and durations.


Choosing Colours and Patterns

On the left side of the expression editor you’ll see a pattern menu. This is where you can customize your robot’s eye colour and pattern.


Here’s what Colour A & B represent:

  • Colour A = Start colour of eyes
  • Colour B = End colour of eyes

Here’s what each transform does:

  • Flip = When Colour A changes to Colour B.
  • Zig Zag = When Colour A is on one eye and Colour B is on the other eye, then they crossfade.
  • Boomerang = When Colour A changes to Colour B and back again.
  • Flat = When the default fade setting is removed.
  • Random = When random colours and a random transform is chosen.

Editing Sound Bars

The grid area is where you customize your robot’s sound. You can edit up to four-notes in your expression. You can see how many notes are left to add on the bottom of the editor.


There are 12 notes on our music grid: A, A#, B, C, C#, D, D#, E, F, F#, G, G#. Drag each sound bar up and down to test and change the notes.


You can also make a note longer or shorter by clicking on the handlebar and stretching it horizontally.


Lastly, click anywhere on the soundbar for the intonation and octave menu.


Here’s what each intonation symbol means:

  • _ = Flat
  • / = Rising
  • \ = Falling
  • ^ = Peaking
  • v = Dipping

The octaves are set from dark to light. The darker the circle, the lower the octave. The brighter the circle, the higher the octave.

Don’t forget Expressions are made up of four notes!

Naming and Mapping Your Expression

To map your expression onto a sensor and event, click on the back button. All of your custom expressions are saved in your My Expressions library.


Drag-and-drop your custom expression into the event circle, the same way you would with a pre-set expression!


You’re Done!
