Welcome to the Collaborative Robotics Lab at Virginia Tech! We create learning and control algorithms for robots that collaborate with people. Our goal is to develop intelligent robots that understand --- and are understood by --- their human partners. These robots personalize their behavior: continually adapting to what the human wants and proactively helping them to achieve their goals. Overall, our research explores the intersection of human-robot interaction, machine learning, control theory, and cognitive science, with applications in personal, interactive, and assistive robots.
