Luna-25. Robotic arm

The lunar manipulator complex developed for the Luna-25 landing mission as part of the instrument group. During the ground tests, first, the kinematics of the manipulator's movements, as it will implemented on the Moon, and the interaction of various instruments worked out: lunar manipulator complex (LMC), a laser ionization mass spectrometer (LASMA-LR), a stationary television system (STS-L) and an IR spectrometer and stereo camera (LIS-TV-RPM). The joint work of this group of devices should ensure accurate guidance of the manipulator to the selected area of the Moon's surface with subsequent sampling, safe transportation of the soil taken into the receiving hole of the mass spectrometer and guidance of the IR spectrometer to various objects on the Moon's surface. The possibilities of the LMC to dig and take soil samples in a vertical chamber using a lunar regolith simulator frozen to cryogenic temperatures in a vacuum with the addition of water ice also investigated.
