A System for Simulating Rotational Motions in Space Using a Robot Arm and Attitude Control Experiments of a Mockup Satellite

Abstract

With the growing demand for micro- and nano-satellites, there is an increasing need for innovative approaches to their development and validation. In this context, the authors propose a methodology for developing and validating attitude control algorithms using a system that simulates the rotational motion of a micro/nano-satellite through a robotic arm. The system comprises a six-axis articulated robotic arm, a robotic software PC, a mockup satellite, and a satellite controller. It calculates the satellite's rotational dynamics and uses the robotic arm to replicate these motions, effectively simulating the space environment. The complete system was experimentally validated, and the results of several related research efforts are presented to demonstrate its effectiveness in simulating attitude control behaviors in space-like conditions.
