Title: Lightweight Deployable Automated Space Systems Using the Least Necessary Resources

Abstract: Over six decades of space exploration have gradually solidified the belief, recently reinforced by advancements in the space economy, that humankind will leave the Earth's cradle and destine for stars. The critical challenge of deep space missions is the efficiency of payloads, constrained by rockets' limited size and capacity. Thus, reducing mass and volume is essential, driving aerospace research to innovate more mass- and volume-efficient structures. This talk will present newly developed analytical methods and advancements in the field of lightweight and deployable automated space systems, specifically focusing on 1) The design of highly flexible space structures that are both lightweight and deployable, utilizing structural paradigms such as tensegrity and origami. 2) Precise dynamic modeling of these structures. 3) Advanced control strategies for deployment and the optimal choice of sensors and actuators. The presentation will also highlight the vital role of interdisciplinary integration of structure and control, illustrating its significant benefits for developing space systems using the least necessary resources. These theoretical approaches are demonstrated by practical applications, such as autonomous lunar drilling rigs and solar panels for In-Situ Resource Utilization, space habitats with 1-g artificial gravity for In-Space Servicing, Assembly, and Manufacturing, space soft robotic arms for Debris Handling and Asteroid Capturing.
