Analysis of the quasi-stability of kinematic parameters for manipulators system during the docking process using the Digital Twin approach

This study analyzes the acceleration of the arms of a dual system of manipulators that aim to achieve the minimum distance by mimicking the process of approaching spacecraft that are trying to connect. The research was performed simultaneously on a real model and its digital equivalent, in accordance with the Digital Twin (DT) approach. The obtained acceleration values show, for some set sampling times, read out positions and velocities, separate distributed regions of achievable values. The Digital Twin, Digital Shadow (DS) and Digital Model (DM) approaches have recently shown great progress in development, both in academic studies and at industrial level. Along a very wide range of applications, we propose some important issues related to satellite technologies.
