Tag Recognition Distance for a Medical Service Robot Using RFID
- 712 Downloads
In this paper, the RFID tag recognition distance is measured for medical robot using RFID. The medical robot has the ability to recognize the face of the patients. The patients’ vital information such as, body temperature, blood pressure, can be measured by the robot. The robot recognizes its location by detecting RFID tags on the floor. The robot also has the ability to navigate the shortest path to the destination. Two kinds of RFID tags are used for the experiment, namely, 13.56MHz and 900MHz bands. The tests were performed by changing the distance and angle between antenna and the tags. Also, the RF power of antenna is varied for the tag recognition. Required antenna RF power and the angle between the read antenna and tag is measured for tag recognition.
