Zeno is 50 cm tall and looks like a brisk boy from a cartoon. He speaks 26 languages and is primarily used in social working - especially because his facial mimic is off the charts. He also likes to say funny things to the children like “I like pizza with candy on it” which captures the children’s attention.
Nao has better motor skills, and he likes to play the game “Simon says” where the children have to follow the robot whether it is a physical movement or an English word that they have to say in Danish. Nao is very physical and uses his whole body, while Zeno primarily stands still and uses his facial mimic.
