About
Alexandros Filotheou is a leading researcher at the intersection of robotics, RFID technology, and autonomous navigation. His work centers on enabling mobile robots—both ground vehicles and drones—to perform Simultaneous Localization and Mapping (SLAM) while simultaneously localizing passive RFID tags in 3D space. A key innovation is his demonstration that a robot with just a single antenna can achieve precise 3D tag localization through intelligent trajectory planning, a breakthrough that eliminates the need for costly multi-antenna setups. His most cited paper (34 citations) presents this method, while his broader portfolio—spanning fingerprinting, phase-based relocking, and real-time performance assessment—has collectively garnered over 140 citations. Filotheou has also advanced robot self-localization, developing techniques such as pose selection with particle filters and correspondence-free scan matching. His work on real-time 3D localization using commercial off-the-shelf RFID equipment addresses practical challenges for inventorying and logistics. Notable achievements include methods for tracking and following moving targets via RFID, and passive global localization using Fourier-Mellin invariant matching. Filotheou’s research offers elegant, scalable solutions that push the boundaries of autonomous robotic perception and RFID-based sensing.
