Important Basis

On-orbit service technology can extend the working life of the spacecraft, and improve the ability to perform various tasks. Docking mechanism is the key equipment of the space docking. The cushion performance of the system determines the dynamic characteristics in the docking process, and it is one of the important factors influencing the docking success or not. It is established that mathematical modeling of the new grasping mechanism in the buffering process, due to lack of the experiment equipments, the dynamic simulation on computer is an effective method to test and verify the parameters or evaluate the performance of the buffer system designed. Simulation analysis is conducted to get the corresponding buffer force for four different sets of buffer parameter, and it provides important basis for docking cushioning structure optimization.

Climbing Stairs

This paper presents a self-propelled travelling mechanism capable of climbing stairs without a sensor or judging algorithm. The developed leg-wheeled mobile robot, which is a type of mechanism to be adaptable to obstacles and to overcome the gravity, uses springs and planetary wheels. The spring is effective when the front wheels start climbing a stair and the planetary wheels with the functions to roll, walk, and jump, thereby passing through stairs and obstacles. A detail design has been performed and a test model has been constructed with a vast range of simulation analysis results. Also, the validity of the constructed test model has been verified through the experiments in climbing the stairs of high step.

Subject. This article examines the issues related to changes in reproduction capacity and heterogeneity of the development of Russian regions. Objectives. The article aims to assess regional differentiation and investigate the main factors influencing the uneven development of the areas. Methods. For the study, we used the methods of comparative and correlation analyses. Results. The article identifies groups of leading and lagging Russian regions and assesses the possibility of convergence of Russian regions according to the analyzed indicators, such as GRP, GRP per capita, and the output of industry. Conclusions. The results obtained can be used when preparing strategic policy documents, spatial development programmes and concepts. The observed heterogeneity suggests that the regions maintain their positions throughout the research period.
