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.
