What is an emotionally expressive robot?
An emotionally expressive communication robot is one that responds to your voice and touch with “feelings” through facial expressions, sounds and gestures. Unlike products that simply repeat preset movements, its defining feature is that it gives a different reaction each time depending on what you do, such as petting it, talking to it or picking it up.
In recent years, as AI-based voice recognition and emotion estimation have become more accurate, more models with rich emotional expression are appearing even in the home-use price range.
How emotional expression works
Most emotionally expressive robots create their reactions with a combination of sensors and motors like the following.
- Touch sensors: detect contact such as petting or hugging
- Microphone and voice recognition: respond to tone of voice and being called
- Camera: some models identify and follow their owner with face recognition
- Movable joints and LED eyes: express emotions through expressions and movement
