About

The Robotics Algorithms & Autonomous Systems (RAAS) Lab is part of the Electrical & Computer Engineering Department at Virginia Tech.

We design algorithms and build systems to enable teams of robots to act as sensing agents. Our research is at the intersection of theory and systems and is motivated by real-world applications to environmental monitoring, infrastructure inspection, and precision agriculture.
