A device for retrieving data from radio frequency identification (RFID) tags is disclosed. The device includes a mobile base, a robotic arm, and a data reading device. 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.
