A system for positioning a work point in three dimensional space has at least three reeving systems spaced apart from one another, with each reeving system having a adjustable support element connected to it. These support elements are also connected to the work point, with the length of the support elements between the work point and the reeving determining the work point's location. Associated with each reeving system is an actuator adapted for releasing and taking up the support element. A control system controls the actuators to release and take up each of the support elements to move the work point with respective to at least three spatial coordinate axes while controlling at least one motion parameter of the work point in a predetermined manner.

System for positioning a work point in three dimensional space

A system for positioning a work point has a plurality of reeving systems spaced apart from one another, with each reeving system having a adjustable support element connected to it. These support elements are also connected to the work point, with the length of the support elements between the work point and the reeving determining the work point's location. Associated with each reeving system is an actuator adapted for releasing and taking up the support element. A control system controls the actuators to release and take up each of the support elements to move the work point with respective to at least two spatial coordinate axes while controlling at least one motion parameter of the work point in a predetermined manner.
