The automatic spraying of huge aviation components is an integration of machinery

electronics

controlling

sensing and software and hardwares. It is the key manufacturing process for automatically coating the large aviation components

and is one of the key technologies to compete in the international market for large aircrafts. This paper mainly introduces the state of current research on coating robots

the latest development of coating robot

and the major problems in development. It also discusses the development tendency of the technology in the future.
