Overview and Prospect of Development of Robot Astronauts
With the completion of China Space Station,the use of robot astronauts to assist or re-place human astronauts has become a prominent research focus.This paper reviews the development status,trends,key technologies,and challenges in the field of robot astronaut services inside the space station by major spacefaring nations over the past two decades and provides an outlook on fu-ture research directions.The progress in robot astronaut research,both domestically and internation-ally,is introduced,and four key technical challenges in this field are analyzed:environmental per-ception,autonomous decision-making,motion planning,and dexterous manipulation.Finally,fu-ture research directions are projected,including advanced sensing technologies,autonomous deci-sion-making technologies,human-robot interaction technologies,and multi-sensor fusion operation technologies.These research efforts are expected to provide more intelligent and efficient support for robot astronauts in performing tasks inside the space station.
