Charlie - I control the forward leg pair, initiate direction and call the heading movements. I pretty much decide where this body goes.
Jessica - I control the rear leg pair. I keep it from tipping over, plant it down and mainly respond to Charlie’s calls.
Eric - I control all speech output, text-to-speech generation and speaker management. If any sound comes from QUO, it’s because I made it happen.
Lily - I control the sensors, discovering objects in the way. I process everything the body can see.
