About
Michael D. Letherwood is a leading researcher in the physics-based simulation and mobility analysis of light autonomous tracked vehicles, with a particular focus on their performance over rough, deformable, and granular terrain. His work is foundational to the development of small reconnaissance robots and unmanned ground vehicles (UGVs) for military applications. Letherwood’s major contributions include creating computational frameworks that simulate vehicle-terrain interactions for vehicles weighing under 100 pounds, enabling engineers to evaluate stability, traction, and mobility without costly physical prototyping. His most cited paper, “Investigating Through Simulation the Mobility of Light Tracked Vehicles Operating on Discrete Granular Terrain” (2013, 23 citations), provides a benchmark methodology for characterizing robot mobility on discrete granular surfaces. Additional work, such as his 2012 study on high-performance computing for lightweight tracked vehicles (8 citations) and his 2005 paper on modeling and simulation for track-laying robotic vehicle stability (3 citations), demonstrates his sustained impact on defense-related UGV research. Letherwood’s simulations have directly supported the U.S. Department of Defense’s efforts to reduce soldier risk through advanced robotic systems, making his research essential for engineers designing next-generation autonomous vehicles for challenging off-road environments.
