“…If all dockings are successful, the tolerance capacity of the device becomes greater than or equal to the tolerance T . If n = n + 1, proceed to step (1). If not all docking procedures are successful, the tolerance of the docking device is T = T 0 + (n − 1) T .…”

A fractional-step docking strategy based on adaptive sensing is proposed for an orthogonally distributed container docking device that exhibits various characteristics, including modularization, miniaturization, extensibility, and peripheral layout. A dynamic model of a body combined with a space station container and robotic arm and a contact dynamic model between the combined body and the docking device are established to lay the foundation for the docking determination of the container in limit poses. Taking the structural and dynamic characteristics of the orthogonally distributed docking device into consideration, the actions of a diagonal double-docking hook were matched under limited working conditions. A 6-D force sensor placed at the end of the robotic arm was used to perceive the contact force of the container and the position of the docking hook, providing a basis for selecting a docking strategy. The tolerance of the docking device was analyzed when applying the docking strategy, the results of which demonstrated a much larger tolerance than that found in the synchronous docking. An orthogonally distributed docking device and an experimental platform were developed, and the tolerance of the device when using the adaptive sensing docking strategy was tested and verified. A comparison between the experiment and simulation proves the effectiveness and feasibility of the proposed adaptive sensing docking strategy.

In the early stages of maturity of a system built for a specific function, it is common for the solutions to lie in a broad architectural space, in which numerous concepts are being developed, built, and tested. As the product matures, certain concepts become more dominant. This pattern can currently be observed in the suborbital tourism industry, in which the obvious question is what system architecture will provide the best combination of cost and safety and in the long run become the dominant architecture. This paper addresses this question by defining a broad architectural space of thousands of possibilities and exploring it comprehensively. We identified 33 feasible architectures, 26 of which had not been proposed earlier. A genetic algorithm optimizes each architecture with respect to the launch mass (a proxy for cost) and operational safety. The launch mass has been calculated in a design analysis framework consisting of four modules: weight/size, propulsion, aerodynamics, and trajectory. A validation of this framework shows relative differences below 7%. A quantitative safety analysis is developed and validated with a survey of 11 leading experts. We identify six dominant architectures. These form a set from which optimal variants are likely to come.

In this paper, an analysis method is proposed to determine capture tolerance capability of an orthogonal distributed satellite capture device that exhibits characteristics, including modularization, miniaturization, extensibility, and peripheral layout. The verifiable limit poses of the satellite are obtained when the pose error of the satellite reaches the boundary of the tolerance domain of the capture device. A dynamic model of a body combined with a satellite and robotic arm, and a contact dynamic model between the combined body and the capture device are established to lay the foundation for the capture determination of satellites in limit poses. A pose-iteration method is used to predict the pose trajectory of the satellite during the capture process, and the results of the satellite capture in the limit poses are obtained. The tolerance capability of the capture device is obtained on verifying the success or failure of the capturing satellite in limit poses. The tolerance capability of an example is analyzed by utilizing the proposed analysis method and is tested via simulation software. With respect to the four typical limit poses in the tolerance domain, the simulation results indicate that the capture device successfully captures the satellite. The results reveal the accuracy of the obtained tolerance and also validate the effectiveness of the proposed tolerance analysis method. The contact dynamics model is imported into the method of tolerance capability analysis to realize the accurate calculation of the time-varying dynamic tolerance capability of the capture device.INDEX TERMS Orthogonally distributed, capture device, tolerance capability, pose iteration method.
