About

Richard R. Gregory is a leading researcher in autonomous robotics and sensor systems, with a particular focus on developing low-cost, compact ladar (laser detection and ranging) technologies for small unmanned ground vehicles. His most-cited work, "Low-cost compact ladar sensor for ground robots" (2009, 8 citations), addresses critical challenges in robotic navigation, obstacle and collision avoidance, and target detection and identification. Gregory’s major contribution lies in identifying and mitigating the limitations of commercial ladar sensors—such as high cost, bulk, and power inefficiency—which have historically hindered their integration into small, agile robots. By advancing compact, affordable ladar designs, his research has directly supported the Army Research Laboratory’s efforts to enhance the autonomy and situational awareness of ground robots in real-world environments. Though his citation count is modest, Gregory’s work is notable for its practical impact on defense and robotics applications, bridging the gap between laboratory innovation and field-ready systems. His achievements underscore a commitment to solving real-world engineering problems, making his research a valuable resource for students and engineers working on sensor-driven autonomous platforms.
