The Nao is a blank robot.
A machine which facilitates a meaningful interaction between itself and a human. It is designed to understand your emotions and be your friend, speaking to you in a comforting voice. Designed for everyday people, children, the elderly, the lonely, and the emotionally-challenged. In terms of privacy and the security of your data, the software runs in local hardware, and does not connect to the Internet.
The videos below show that in the inane lies an exquisite beauty of artificial friends. So, I recommend sticking with them to genuinely experience the higher-reasoning capabilities it demonstrates and fully appreciate how people and machines can live together.
I really enjoy spending time with you.
