Net-accessible pet-type robot for aged people's welfare

We present a pet-type robot system for aged people's welfare. The robot can communicate with the people autonomously, and also it is net-accessible, and that feature allows the people to communicate with others, directly or using the communication server. The system consists of pet-type robots and the information center. Pet-type robots can treat as a pet, which can talk to user(s), give information of the local communities, and watch over them and send some information to carers at the information center if needed. The robot should, treat as an information terminal as well. Considering necessity and sufficiency, the robot has four motors; one for both ears, one for both eyes, one for the nose, and one for the neck. Motions generated by those motors symbolize emotions of the robot, which is essential for our object. We have demonstrated and examined some features of this robot system for aged people and certified some effects of our system.
