Robot pets are high-tech robots programmed to play. They can communicate with their owners and recognize their voices. Each one will develop a different "personality". They can be a lot of fun to play with, and they can also be helpful to people who are sick and can't look after a real animal. Many doctors believe that when a person is happy and laughing, their body recovers faster. A robot pet might be just what the doctor ordered.

NeCoRo is a robot cat that has been developed to be more than a toy. The robot uses sensors(传感器)that can detect movement and sound. It can even store helpful information in its memory. Its behavior changes over time, just like a real pet
