About

Robert Chevalier’s research lies at the intersection of human-robot interaction and explainable autonomy, with a focus on building trustworthy, collaborative robotic systems. His most influential work, “Explaining robot actions” (2012, 74 citations), pioneered methods for robots to generate natural-language explanations of their own behavior—enabling a robot to answer “why” questions about its decisions, such as why it turned left in a hallway. This foundational contribution directly addresses the critical challenge of human trust in autonomous systems. Chevalier also played a key role in the DARPA Robotics Challenge Finals as part of Team TROOPER, where he co-developed an architecture for human-guided autonomy that balances automated execution with human oversight during unexpected events. His work on graduated automation for humanoid manipulation further explores adaptive control strategies, allowing robots to shift between autonomous and teleoperated modes as environmental uncertainty changes. Through these contributions, Chevalier has helped define how robots can transparently communicate their reasoning, making them safer and more effective partners in complex, real-world tasks.
