Common Voice character's name

This guy. Mars (Hmmm, "Mars"?)
What is the name of the character on commonvoice.mozilla.org and voice.mozilla.org?

Also, is this guy a robot?
Is the red one, and the blue one and the green one different? What does it mean?
Who designed it?

When Common Voice grows up, will we be able to talk to this guy?

I always read the information on commonvoice.mozilla.org as if this guy were talking.
