摘要

The paper highlights the most recent achievements ofrnthe team in the field of advanced space mechanisms:rnelectromagnetic hammering drive, lock and releasernmechanism, and sample container separationrnmechanism used in the CHOMIK (Polish word forrnhamster) sampling device for the Phobos-Gruntrn(Phobos Sample Return) mission. The principle ofrnoperation of the CHOMIK instrument is based on thernMUPUS penetrator device for the Rosetta mission;rnhowever, the features of construction are significantlyrndifferent. Two of the mechanisms are entirely new andrnthe third one is intrinsically improved. Moreover, arnnumber of tribological tests on materials and surfacernlayers used in the mechanisms have been conductedrnusing a newly build vacuum pin-on-disk tribometer.
