Foldable light manipulator with joint axes in orthogonal relations and six degrees of freedom

The utility model discloses a foldable light manipulator with joint axes in orthogonal relations and six degrees of freedom. The foldable light manipulator is characterized in that a first rotary joint, a second rotary joint, a large arm connecting rod, a third rotary joint, a fourth rotary joint, a fifth rotary joint and a sixth rotary joint are sequentially arranged on a base, a tail-end claw with a single degree of freedom is connected with an output end of the six rotary joint, the axis of the first rotary joint is coaxial with the base and is perpendicular to the axis of the second rotary joint, the axis of the second rotary joint is parallel to the axis of the third rotary joint, the axis of the third rotary joint is perpendicular to the axis of the fourth rotary joint, the axis of the fourth rotary joint is perpendicular to the axis of the fifth rotary joint, the axis of the fifth rotary joint is perpendicular to the axis of the sixth rotary joint, and the axis of the fourth rotary joint, the axis of the fifth rotary joint and the axis of the sixth rotary joint intersect with one another at a spatial point. The foldable light manipulator has the advantages that the manipulator is simple in integral structure and is light, and accordingly the optimal operational flexibility of the tail end of the manipulator can be guaranteed.
