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.
