About

Fiona Stevens McFadden is a leading roboticist specializing in wheel–terrain interaction for mobile robots operating in challenging outdoor environments. Her research focuses on the critical challenge of maintaining vehicle controllability and mission success on rough, uneven terrains. Her major contributions include pioneering methods for *in situ* slip and skid estimation, allowing robots to detect and mitigate surface hazards in real time without relying on pre-mapped terrain models. Her 2022 paper, "In situ slip estimation for mobile robots in outdoor environments," has garnered 13 citations, establishing a foundational approach for traction control in field robotics. Building on this, her 2023 work, "In situ skid estimation for mobile robots in outdoor environments," with 7 citations, extends the framework to address lateral skidding—a key source of trajectory tracking errors. Together, these contributions provide practical, sensor-driven solutions that enhance the autonomy and safety of robots deployed in agriculture, search-and-rescue, and planetary exploration. Stevens McFadden’s work is essential reading for students and researchers developing robust navigation systems for real-world, unstructured terrains.
