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.
