About

Roger A. Chadwick is a pioneering researcher in human-robot interaction, specializing in the cognitive and perceptual challenges of controlling multiple semi-autonomous robots. His work focuses on understanding how a single operator can effectively manage multiple unmanned ground vehicles (UGVs) in high-stakes environments like urban search and rescue and military operations. Chadwick’s major contributions include identifying key cognitive bottlenecks—such as monitoring, responding, and detecting targets—that arise when operators must integrate information from multiple robot feeds. His innovative, low-cost simulation methods (e.g., using commercial toys and software) have made his research accessible and replicable, earning his most-cited paper, “The Impacts of Multiple Robots and Display Views” (2005), 34 citations. He also co-authored “Operating Multiple Semi-Autonomous Robots” (2006, 29 citations), which demonstrated how semi-autonomous robots can reduce operator workload while maintaining performance. Chadwick’s work has informed interface design principles that improve situational awareness and reduce errors, impacting both military robotics and emergency response systems. His practical, cost-effective approach to cognitive analysis remains a model for human-robot interaction studies.
