About

Vassilios Petridis is a robotics and autonomous systems researcher whose work centers on the challenging problem of Simultaneous Localization and Mapping (SLAM) — a fundamental capability that enables robots to navigate and build representations of unknown environments in real time. His most significant contributions lie in developing computationally efficient SLAM algorithms that reduce the complexity inherent in probabilistic mapping approaches. Most notably, Petridis introduced L-SLAM, a low-dimensionality variant of the widely used FastSLAM family of algorithms, which achieves dimensionality reduction in the particle filter framework while handling unknown data association — a particularly difficult aspect of real-world robotic navigation. This work, first presented in 2011 and extended to full 6 degrees-of-freedom in 2014, has attracted over 35 combined citations, reflecting meaningful traction within the robotics community. Beyond L-SLAM, Petridis developed G-SLAM, a generative approach that models the environment as a set of scattered points, offering an alternative probabilistic perspective on the mapping problem. Collectively, his research advances the practical deployment of autonomous robots in complex, unstructured environments, contributing valuable algorithmic innovations to the broader field of mobile robotics and state estimation.
