An Innovate Detumbling Method for a Non-Cooperative Space Target via Repeated Tentative Contacts

open access: yesIEEE Access, 2022
On-orbit removing tumbling targets is a critical research issue for future space missions. Repeated tentative contacts by the robot can be used to eliminate the rotational motion of a tumbling target.
