The space arm itself is an intelligent robot with precise operation and visual recognition capabilities. It has both autonomous analysis capabilities and can be remotely controlled by astronauts. It is a high-end aerospace equipment that integrates mechanical, visual, dynamic, electronic and control disciplines. It is a new direction for the development of space institutions pioneered by the space shuttle. With the rapid development of space technology, especially the birth and successful application of space stations, space shuttles, space robots, etc., the space manipulator arm has entered space as a key technology for on-orbit support and service, and has attracted more and more attention. Through the actual use of the space shuttle and the International Space Station, the space manipulator arm has shown strong application capabilities and broad application prospects, and has played a great role in promoting the development of space science and applications. It can be said that it is a product of the increasing number of human space activities and the continuous expansion of the scale of activities.
On July 4, 2021, Chinese astronauts Liu Boming and Tang Hongbo, wearing the new generation of "Feitian" extravehicular space suits independently developed by China, have successfully exited the Tianhe core module node module. In the future, with the support of the manipulator arm, they will cooperate with each other to carry out operations such as the assembly of relevant equipment outside the space station.
