That's because Nadine is a socially intelligence robot that actually looks like a human, too. It has her own personality, as well as moods and emotions, according to an ABC News report.
Nadine was created by Professor Nadia Thalmann as a receptionist for a new media showcase at NTU. Thalmann envisions the robot as becoming commonplace in the coming years as a receptionist in offices and homes.
Nadine was created to look like Thalmann, featuring soft skin and brunette hair, smiling when greeting a person and engaging in eye contact during conversation. She can even shake hands.
The software behind Nadine is as powerful as Apple's Siri or Microsoft's Cortana, NTU claims.
Nadine can express emotions like happiness or sadness depending on the subject of the conversation. She also has the ability to remember things.
Social robots could represent an important development as societies have populations that grow ever older in average age. The social robots could help a shrinking workforce and become personal companions for the elderly, assisting with elderly services.
NTU also developed a robot named EDGAR. He was designed to be a tele-presence robot that can project upper-body movements and facial expressions of his user, and basically act out a script.
Although robots have a long way to go before they enter conventional use, experts think we may be getting closer to seeing them on a day to day basis.
