Development of the robotic lunar surface sampler

Introducing the characteristic and existing difficult in the lunar surface sampling.Ac-cording the lunar surface environment,characteristic of the lunar sample and the requirement of Chang’e program phase 3,we chose the sampling method reasonably and developed a six degree of freedom robotic lunar surface sampler.Then analyzed the sampling theory,mechanical system and principle of movement.At last,sampling experiments was carried on the calcareousness powder,which validates the sampler’s ba-sic function and feasibility.
