Attendant robot for elderly service using sensor network system

The authors developed an Attendant Robot system for the elderly. The robot system is used to prevent user from being at a loss. The system uses ZigBee-3D acceleration sensor and Kinect sensor. Attendant Robot mounts the ZigBee access point, and the ZigBee accelerometer tag is attached to users. The ZigBee access point knows that user comes near to Attendant Robot by finding the tag. This tag has a unique ID, so Attendant Robot reacts to correlative ID only. Kinect sensor detects people who stand in front of the Attendant Robot. This system recognizes user by using function of Kinect and ZigBee sensor. Attendant Robot navigates user using this system. In this paper, the authors set up the proposed system and performed experiment.
