About

David A. Spencer is a pioneer in autonomous systems and human-robot collaboration, with a career spanning planetary exploration and underwater robotics. His work on the Mars Surveyor 2001 Lander (1998, 10 citations) established foundational precision landing technologies critical for future Mars missions, including human exploration. Spencer’s most impactful contribution is the development of the switched linear quadratic regulator (SLQR) for human-robot collaborative guidance (2015, 12 citations), enabling autonomous underwater vehicles to seamlessly transition between human and machine control. He further advanced multi-robot systems by integrating trust-based interaction into symbolic motion planning (2016, 8 citations), addressing the critical challenge of ensuring safe and reliable task execution when humans supervise multiple robots. Spencer’s research uniquely bridges space and marine domains, demonstrating how control theory and human factors can enhance autonomy in extreme environments. His work on trust-aware planning has influenced subsequent studies in human-robot teaming, while his precision landing concepts remain relevant for NASA’s ongoing Mars exploration efforts. Spencer’s career exemplifies how foundational engineering principles can enable ambitious robotic missions across vastly different operational contexts.
