A project of a promising manned space station for the construction and maintenance of a large-sized promising manned spacecraft (PMS) with artificial gravity is presented. A scheme for the construction and operation of a robotic complex for the construction and maintenance of a spacecraft with artificial gravity is proposed. The composition of the complex and the procedure for assembling spacecraft segments on it are described. A project of a multifunctional orbital station is presented, which is a revised project that combines the requirements for the technical implementation of a manned orbital station and a robotic complex. A review of current projects of manned orbital stations was carried out.
