I Want To Add 3 Ultrasonic Dis

I want to add 3 ultrasonic distance sensor in Six. Using these, I will mimic emotions of shyness, fear and aggression. For example if someone is at a distance of around 20 inches, it will wave towards that direction, if something comes closer than 10 inches, Six will start moving away, if something comes closer than 5 inches, it will curl its legs closest to the body.
