Abstract: An overall technical solution for Five-hundred-meter Aperture Spherical radio Telescope (FAST) operation and maintenance robot was proposed to address issues such as precise equipment installation and replacement of feed receivers,complex disassembly and assembly processes,limited installation space in the feed cabin, limited installation space at the feed cabin docking platform,a large number of connecting bolts,large size and weight of the lower platform,high installation accuracy requirements,long replacement time,and transportation difficulties during FAST operation. Through the analysis of robot overall technical requirements,robot overall technical design,key robot technology research,and simulation analysis,the solution meets the application needs of positioning,identification,disassembly,and transportation during the disassembly and assembly of feed receivers,reduces the time and economic costs of operation and maintenance,ensures the safety of FAST operation and maintenance,improves usage efficiency,and extends the observation time of FAST throughout the year,promoting the output of astronomical achievements.
