About

Jinghai Sun is a key figure in the development of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), the world’s largest single-dish radio telescope. His research centers on the structural mechanics and control of large-scale cable-driven parallel robots, with a specific focus on the feed support system that positions FAST’s receivers with extreme precision. Sun’s major contributions include the preliminary running and performance testing of FAST’s massive cable robot, a critical achievement documented in his most-cited work (13 citations). He also developed a source switching planning method for the feed support system, solving the complex problem of efficiently moving receivers between observation targets to maintain telescope stability and accuracy. This work directly addresses the operational challenges of FAST’s unique design, where a 30-ton cabin is suspended by six cables over a 500-meter dish. Sun’s engineering solutions have been instrumental in enabling FAST’s high-precision observations, contributing to its status as a world-leading astronomical facility. His research exemplifies the intersection of robotics and large-scale infrastructure, with lasting impact on radio telescope operations.
