About

Jong-Woon Yoo is a leading figure in space robotics, specializing in autonomous systems for microgravity environments. His research focuses on the development of free-flying robots designed to assist astronauts aboard the International Space Station (ISS), with key contributions in avionics, perching mechanisms, and localization. Yoo’s most notable work introduces NASA’s Astrobee—a cube-shaped autonomous robot engineered to offload routine and repetitive tasks from crew members. His 2015 paper on Astrobee’s avionics and perching systems, cited 12 times, details the critical subsystems that enable the robot to dock and recharge autonomously, a foundational achievement for sustained in-orbit operations. Complementing this, Yoo pioneered WiFi-based localization for free-flying robots on the ISS, as outlined in his 2014 study (5 citations). By collecting signal strength samples, building WiFi maps with Gaussian processes, and implementing particle filter-based localizers, he solved a key navigation challenge in the station’s complex, metallic environment. Together, these contributions establish Yoo as a key architect of next-generation robotic assistants, enhancing astronaut productivity and paving the way for more autonomous space station operations.
