Internet based robot in healthcare may significantly facilitate the current operation model in hospital. In this study, a wireless internet based robot is designed for physicians to communicate with the patients at a distance. A simple type of robot with three motors for driving three all-direction wheels is used as the basic structure. It also contains four ultrasonic transducers, one RFID reader, one web-based camera, one high sensitive microphone, and an IR-based positioning device. Besides, a plate computer is attached on the top for controlling all the devices. The physician may control this robot remotely through wireless network, to communicat with the patients in hospital. The movement of the proposed robot is controlled either by the remote commands given by the physician, or by IR based navigation system. From the testing results, this robot works well as designed for facilitating the distant patients ward checking. Through the wireless network and auto-navigation, the physicians may remotely control the robot to the specific patient room, to read the electronic record, and to communicate with the patient using notebook computer or PDA.
