About

M. Matthews is a leading researcher in planetary rover mobility, specializing in terrain trafficability analysis and soil mechanics for off-road autonomous systems. Their foundational survey on terrain trafficability and soil mechanical property identification for planetary rovers (83 citations) remains a key reference in the field, synthesizing decades of work on how rovers interact with deformable, extraterrestrial soils. Matthews advanced this understanding by developing soil simulant sourcing strategies for the ExoMars rover testbed (39 citations), enabling realistic ground testing for European Space Agency missions. A major contribution is the hybrid wheel-leg sinkage detection method for trafficability assessment (21 citations), which directly addresses the nongeometric hazards that caused the Mars Exploration Rover Spirit’s mission-ending entrapment. Matthews also pioneered multi-level soil sensing systems to identify safe trafficability zones for extra-planetary rovers, and proposed forward sensing architectures for safe long-range travel, reducing reliance on day-to-day human planning. Collectively, their work bridges soil mechanics, sensor fusion, and autonomous navigation—critical for future long-duration planetary exploration where real-time hazard detection is essential.
