An industrial robot for movement of an object in space comprising a stationary platform, a movable platform adapted for supporting the object, and a first, a second and a third arm to which the platforms are joined. The first arm comprises a first actuator, a first supporting arm influenced by the first actuator and rotatable around a first axis, and a first linkage. The second arm comprises a second actuator, a second supporting arm influenced by the second actuator and rotatable around a second axis, and a second linkage. The third arm comprises a third actuator, a third supporting arm influenced by the third actuator and rotatable around a third axis, and a third linkage. The second supporting arm is freely mounted around a cross-beam that is arranged at right angles to the second axis. |
