Abstract: Drilling and coring, due to their efficient penetrating and cutting removal characteristics, have been widely applied to planetary sampling and returning missions. In most autonomous planetary drilling, there are not enough ...

Abstract: This paper presents a geometric approach for design and synthesis of deployable/foldable single loop mechanisms with pure revolute joints. The basic kinematic chains with symmetric mobility are ...

Abstract: In the third phase of the Chang’E project, a drilling and coring device mounted on a lunar probe will be sent to the moon to acquire samples of lunar soil within a certain depth (subsurface lunar soil). Interaction between ...
