About

F.J. Sweeney is a pioneering researcher in autonomous mobile robotics, with a career-long focus on deploying intelligent machines in hazardous environments—particularly nuclear facilities. Sweeney’s most significant contributions center on the HERMIES-III robot, a large human-scale platform designed for complex, real-world tasks. The landmark “DEMO 89” experiment (13 citations) demonstrated the robot autonomously planning paths and navigating to clean up a simulated chemical spill, establishing a benchmark for field robotics. Sweeney also advanced perception systems, notably through work on segmentation and cooperative fusion of laser radar image data (6 citations), a critical step for robots interpreting 3D scenes. A key achievement was the proof-of-principle demonstration using HERMIES-III to autonomously inspect waste storage drums for radioactive contamination (4 citations), directly reducing human exposure to hazardous environments. Further work included designing remote inspection methods for the Reactor Vessel Auxiliary Cooling System (3 citations) in advanced liquid metal reactors. Sweeney also helped shape the field through the DOE/NE University Program in robotics for advanced reactors (2 citations), fostering academic collaboration. With a career dedicated to making robots capable of operating in the most dangerous conditions, Sweeney’s work has laid essential groundwork for autonomous systems in nuclear safety and environmental remediation.
