On Using Passive RFID Tags to Control Robots for Path Following

Although very few robots actually go to Mars, we continue to design these machines as if they were organisms operating in a totally unknown and hostile environment. In fact, in most situations, the environment is not only predictable, but it can also be manipulated so that the missions of the autonomous robot may be supported, by including sensors, actuators, computing and communication equipment. One of the most convenient ways to manipulate the environment is to deploy a number of RFID devices, capable of storing a variety of digital data, aimed to provide autonomous robots with valuable navigation information. As a result, the on-board equipment can be significantly reduced, along with the power requirements, and the overall cost of the robots. While the vast majority of the applications of the RFID technology for robot control are related to robot localization and mapping, this paper presents an experiment aimed to demonstrate the possibility of using RFID tags for path following.
