Genetic Fuzzy System-based Control for Final Approach of Spacecraft Rendezvous and Proximity Operations
Daegyun Choi, Donghoon Kim, Henzeh Leeghim
In-space servicing has been receiving great attention to extend the operation of spacecraft with defective components. This requires rendezvous and proximity operations for a chase…
Genetic Fuzzy System-Based Multi-Robot Coordination for Planetary Missions
Daegyun Choi, Donghoon Kim
This paper proposes a decentralized approach for a multi-robot system (MRS) using a genetic fuzzy system to perform a collaborative object transportation task that minimizes the to…
SPURS: Massive Stars, Dense Gas, and Ly Escape in GN-z11 at
Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +6
We present ultra-deep {\it JWST} spectroscopy of GN-z11 () obtained through the SPURS Cycle 4 Large Program, providing the deepest rest-UV view yet obtained of a galaxy at…
Fuzzy-Based Control Method for Autonomous Spacecraft Inspection with Minimal Fuel Consumption
Daegyun Choi, Donghoon Kim, Henzeh Leeghim
This study explores an energy-efficient control strategy for spacecraft inspection using a fuzzy inference system combined with a bio-inspired optimization technique to incorporate…
Modeling and Control Framework for Autonomous Space Manipulator Handover Operations
Diego Quevedo, Sarah Hudson, Donghoon Kim
Autonomous space robotics is poised to play a vital role in future space missions, particularly for In-space Servicing, Assembly, and Manufacturing (ISAM). A key capability in such…
Understanding and Utilizing Dynamic Coupling in Free-Floating Space Manipulators for On-Orbit Servicing
Gargi Das, Daegyun Choi, Donghoon Kim
This study proposes a dynamic coupling-informed trajectory optimization algorithm for free-floating space manipulator systems (SMSs). Dynamic coupling between the base and the mani…
