据科学家预测,到21世纪20年代,除了在月球建造宾馆外,空间站、空间实验室、空间工厂等也将会有较大的发展,这将需要大批的“太空建筑工”。然而,为了保证“太空建筑工”在月球上正常工作,每人每天得花费50万美元。这是多么昂贵的代价!因此,一些发达国家正在积极研制空间机器人,以充当“太空建筑工”。 According to scientists’ predictions, by the 1920s, apart from building hotels on the moon, space stations, space laboratories, space factories, etc. will also have greater development, which will require a large number of “space construction workers.” However, in order to ensure that “space builders” work on the moon, they spend 500,000 U.S. dollars a day. This is how much the price is expensive! Therefore, some developed countries are actively developing space robots to serve as “space builders.”
