PLATFORM MANIPULATOR WITH THREE DEGREES OF FREEDOM Russian patent published in 2021 - IPC B25J1/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, in particular to robotics, and can be used in spatial manipulators of a parallel structure used in automatic lines, training centers and surgery. The manipulator has a movable platform and a support base. The platform is made in the form of a circular sector, with the sides of which three rod movable supports are movably connected. Each support is made in the form of a supporting two-pair link. The first link is made with one-movable rotational and two-movable cylindrical kinematic pairs. The second link has two two-movable cylindrical kinematic pairs with non-parallel axes of rotation. The third link is made with a two-movable cylindrical kinematic pair and a three-movable spherical joint.

EFFECT: simplified design and reduced size of the manipulator, increased rigidity and positioning accuracy, and increased working space are provided.
