About

Raphael Prinz is a robotics researcher focused on autonomous navigation in extreme, off-road environments—including planetary analogs here on Earth. His work sits at the intersection of field robotics, terrain perception, and machine learning, with a particular emphasis on enabling robots to traverse unstructured, hazardous terrain safely and efficiently. Prinz’s major contributions include developing traversability analysis methods that combine real-world locomotion experiments with Earth observation data, allowing robots to assess and predict terrain difficulty before moving. He also pioneered the use of convolutional neural networks to generate off-road navigation maps, translating satellite imagery into robot-dependent cost maps that guide path planning. These innovations were demonstrated during the AMADEE-20 Mars analog mission in the Negev Desert, where Prinz helped implement a robotic exploration cascade using aerial and ground platforms. His most cited paper (12 citations) on traversability analysis for off-road environments has become a reference point for researchers working on autonomous navigation in challenging terrain. Prinz’s work directly supports future planetary exploration and terrestrial robotics in agriculture, search-and-rescue, and defense.
