Abstract
A portal system is described which consists of two translational axes and two rotary axes which are so arranged and controlled that every point within a cubic working space can be computed and reached. As a result of this special kinematic construction the total complexity for the frame and also the mechanical complexity and cost are substnatially reduced in comparison to customery portal systems.
