This paper presents an idea of wirelessly powered mobile sensors utilizing cloud management system similar to the swarm robotics. Sensors are based on the previously developed wireless passive sensors working with RFID protocol in the HF range. Preliminary research presented in this paper is related to the energy harvesting efficiency evaluation and the possibility to wirelessly power an electric motor. Performed experiments show that the magnetic field generated by the RFID reader antenna provides enough amount of energy not only to perform communication, measurements and computation, but to power the actuators as well. Achieved results state a base for further investigation in the area of wireless passive mobile sensors.
