The Robotics Algorithms & Autonomous Systems (RAAS) Lab is part of the University of Maryland. Previously, the lab was located 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.

The lab is affiliated with the Department of Computer Science, UMIACS, and the Maryland Robotics Center at the University of Maryland.
