Abstract: A method of positioning a RFID tag by using four antennas associated with an algorithm is disclosed. A positioning space is sliced into several spatial boxes with an equal size. The center of each spatial box is assumed roughly as the target position and thus the positions are used to calculate the average errors and root mean square errors. Thereafter, the errors of all spatial boxes are compared and chosen the smallest error one from them as a new positioning space. The RMSE of the selected spatial box is then compared to a predetermined value. A correcting quantity in three axial directions is then added on the coordinate of the initial position and served as a new initial position. The processes repeated till the RMSE meets the termination condition.

The robotic arm is attached to the mobile base. The data reading device employed to collect the data of electric tags is attached to the end of the robotic arm. A device for retrieving data from an RFID tag arrives at the position, where the electric tag is, by moving the mobile base and adjusting the height of the robotic arm. The movement is controlled according to the position and the height of the electric tag. Finally, the data reading device reads the data stored in the electric tag.

Abstract: A method of positioning a RFID tag by using four antennas associated with an algorithm is disclosed. A diagram is depicted, which is about relationships between the RSSI and distance according to environment of the space. Next, four antennas are arranged in the space. Four measured distances analyzed from the RSSI curve are measured. Thereafter, a position of the RFID tag is assumed at the center of space. The position is served as an initial coordinate. Subsequently, the root mean square error (RMSE) is determined. If the RMSE is small than or equal to termination criteria, the coordinate is regarded as the position of the RFID tag, otherwise the initial 3-D coordinate is updated by adding some correcting values at each measuring weight. This process is repeated till the RMSE meets the assigned condition.
