FIELD: physics.
SUBSTANCE: spatial mechanism comprises a base, an output link, three kinematic chains, each comprising an input turning pair, an initial turning pair, an intermediate turning pair, a terminal turning pair and an output turning pair. The axes of the initial, intermediate and terminal turning pairs are parallel to each other; the axis of the initial turning pair is perpendicular to the axis of the input turning pair and the axis of the terminal turning pair is perpendicular to the axis of the output turning pair. Each turning kinematic chain is provided with a rotary drive, the axis of which is perpendicular to the axis of the input turning pair, and the input and output turning pairs can be installed to allow parallel arrangement of the axes thereof or intersection of the axes at one point.
EFFECT: invention enables translational three-coordinate movements in space and spherical orientating movements - rotation around one point.
