Design of RFID based Mobile Robot and its Implementation in Pharmacy Dispensing System
Abstract
Autonomous navigation in mobile robotics generally requires solving two problems pertaining to the localization and navigation of a mobile robot in an environment not known with certainty. The localization is done using RFID tags, which gives the information about the position. The RFID tags act as waypoints to guide the robot to the desired target. The tag ID of the waypoints is stored in the robot’s memory. Our proposed technique will be useful for real-world robotic applications such as pharmacy dispensing system. Each rack of the Pharmacy system is fitted with an RFID tag. A robot mounted with an RFID reader navigates along the racks using the position information from the RFID tags. The RFID reader checks the signal from the RFID tag and estimates the robot’s position. Once the robot reaches the target rack, a counter circuit keeps track of the number of drugs loaded from the particular rack based on the user-defined count. Experimental results show that the proposed system is time efficient and reduces manpower, human prone errors and the complexity of the pharmacy infrastructures.
