About
William Raff is a key figure in robotic sensing for planetary exploration, with his work centered on force-torque sensor calibration and manipulation systems for extreme environments. His most cited paper, "Two-stage calibration of a 6-axis force-torque sensor for robust operation in the Mars 2020 robot arm" (2021, 11 citations), details a critical innovation that enabled the Perseverance rover’s Sampling and Caching Subsystem to precisely collect and preserve Martian rock and soil samples. This two-stage calibration method ensures sensor accuracy despite temperature swings and mechanical wear, directly supporting the mission’s core objective. Raff’s contributions extend beyond this landmark achievement, as his research addresses the broader challenge of making robotic manipulators reliable in space—where recalibration is impossible. His work has been instrumental in advancing sensor robustness for NASA’s most ambitious sample-return campaign, and his techniques are now informing next-generation rover designs. With a focus on practical, mission-critical solutions, Raff exemplifies how rigorous engineering can push the boundaries of in-situ planetary science, earning him recognition as a vital contributor to the success of Mars 2020.
