Abstract

The invention discloses a moonscape sampling mechanical arm, wherein the mechanical arm is locked on an external explorer in a compaction state through a compaction release mechanism, the mechanical arm realizes unfolding through a multi-joint synergic movement after unlocking, and realizes sampling point confirmation on sampling region imaging according to the touch of moonscape by a moon-touching sensing component at the tail end of the mechanical arm and a camera mounted on the mechanical arm, and a sampler at the tail end of the mechanical arm realizes the collection of moonscape samples.The invention can realize multipoint sampling within a designated moon range under an unmanned condition.

Description

technical field [0001] The invention relates to the technical field of deep space exploration, in particular to a lunar surface sampling mechanical arm. Background technique [0002] At present, there are mainly two methods of lunar sampling that have been successfully applied. One is astronauts + hand-held sampling tools to achieve multi-point sampling on the moon, such as the US Apollo series of lunar exploration missions; the other is remote-controlled rotary drilling devices to achieve fixed positions on the moon. Drilling samples, such as the Luna series of lunar exploration missions of the former Soviet Union. Neither of these two sampling methods has achieved multi-point sampling within the specified range of the moon under unmanned conditions. Contents of the invention [0003] In view of this, the present invention provides a lunar surface sampling mechanical arm, which can realize multi-point sampling within a specified range of the moon under unmanned condition...
