Method for determining a movement limit of a movement system which has a platform which can be moved in several degrees of freedom with respect to a fixed reference plane by means of actuators, wherein the actuators are arranged in an articulated fashion both in the fixed reference plane and on the movable platform and are designed to change length in order to move the movable platform, comprising the steps which are carried out by means of a microprocessor-controlled computing unit: a) defining a degree of freedom of the movement system for which the movement limit is to be determined, b) making available a current movement system state of the movement system with respect to a predefined coordinate system, c) calculating an articulation trajectory for each upper articulation point of the actuators at the movable platform along the fixed degree of freedom taking into account the current movement system state in the predefined coordinate system, d) calculating the maximum possible position of each upper articulation point on its calculated articulation trajectory in the direction of the defined degree of freedom as a function of an extreme deflection of the corresponding actuator of the respective upper articulation point, and e) calculating the movement limit of the movement system with respect to the defined degree of freedom as a function of the maximum possible positions of the upper articulation points on their articulation trajectories, characterized in that the maximum possible position of an upper articulation point on its calculated articulation trajectory is calculated in the direction of the defined degree of freedom in that a movement space of the respective actuator with respect to its extreme deflection in the case of a movement of the actuator about the lower articulation point in the fixed reference plane is calculated, and the point of intersection of the calculated articulation trajectory of the respective upper articulation point with the movement space of the actuator is calculated. a) defining a degree of freedom of the movement system for which the movement limit is to be determined, b) making available a current movement system state of the movement system with respect to a predefined coordinate system, c) calculating an articulation trajectory for each upper articulation point of the actuators at the movable platform along the fixed degree of freedom taking into account the current movement system state in the predefined coordinate system, d) calculating the maximum possible position of each upper articulation point on its calculated articulation trajectory in the direction of the defined degree of freedom as a function of an extreme deflection of the corresponding actuator of the respective upper articulation point, and e) calculating the movement limit of the movement system with respect to the defined degree of freedom as a function of the maximum possible positions of the upper articulation points on their articulation trajectories, characterized in that the maximum possible position of an upper articulation point on its calculated articulation trajectory is calculated in the direction of the defined degree of freedom in that a movement space of the respective actuator with respect to its extreme deflection in the case of a movement of the actuator about the lower articulation point in the fixed reference plane is calculated, and the point of intersection of the calculated articulation trajectory of the respective upper articulation point with the movement space of the actuator is calculated.
