An industrial robot including a platform arranged for carrying an object. A first arm is arranged for influencing the platform in a first movement and includes a first actuator having a first path and a first carriage linearly movable along the first path. A second arm is arranged for influencing the platform in a second movement, and includes a second actuator having a second path and a second carriage linearly movable along the first path. A third arm is arranged for influencing the platform in a third movement. A control unit controls the movements of the platform. The first and second arms are arranged rotatable in such way that the platform is movable between opposite sides of a second plane passing through and continuously following the first and second carriage. The control unit includes a control adapted to upon command perform a reconfiguration of the platform and the arms of the robot. The reconfiguration includes moving the platform between opposite sides of the second plane.
