A manipulator includes a mount member, a base member with threaded openings and an aperture, two links, and an output member with threaded openings and an aperture. The manipulator also includes three motors mounted to the mount member and three drive trains connected to the motors, respectively.

Provided is a fixed point mechanism. In the fixed point mechanism, when a drive torque acts on a first connecting rod member (100) or a slide block device (110), the fixed point mechanism can realize a rotation movement around a fixed point; when a drive torque acts on a fourth connecting rod member (103) or a sixth connecting rod member (105), the fixed point mechanism can realize a telescopic movement relative to the fixed point; and when a drive torque acts on the first connecting rod member (100) or the slide block device (110), and another drive torque acts on the fourth connecting rod member (103) or the sixth connecting rod member (105), the fixed point mechanism can realize a rotation movement around the fixed point and a telescopic movement relative to the fixed point. That is, the fixed point mechanism has two degrees of freedom of the rotation movement around the fixed point and the telescopic movement relative to the fixed point.

An industrial robot with parallel kinematics is proposed which is equipped with a robot base (1), a carrier element (2) for receiving a gripper, a tool or a machine element, at least two moveable actuating units (4), one of which ends is connected to actuating-unit drives (6) arranged on the robot base (1) and the other end is moveably connected to the carrier element (2), a telescope (13) that is moveably arranged between the robot base (1) and the carrier element (2), a first joint (17) with multiple degrees of freedom, by means of which joint the telescope (13) is moveably held on the robot base (1), a second joint (23) with multiple degrees of freedom, by means of which joint the telescope (13) is moveably held on the carrier element (2), whereby the position of the first joint (17) can be displaceably arranged relative to the robot base (1).
