RFID from the air - Product localisation with RFID scanner, carried by autonomic drone, aided by visual markers

We investigate the possible applications of RFID technology. The focus of the examination is to define restrictions of RFID technologies, and to extend the potential application area by means of supporting hybrid technologies. Of all the difficulties it is the range what represents the hardest problem. A possible way to extend it, is to approximate the scanner to the tag with a robot, supported with image processing. The robot we chose is an in-door, unmanned aerial vehicle (drone, or quadrocopter). Hereby we would like to publish our experiences and observations so far.
