Abstract: The device serves for moving a movable platform (2) in respect to a base (1). The connection between platform and base is established by six legs (4a-4f), which are connected to the platform in articulated manner. At the base side, they rest in articulated manner on sliding carriages (6a-6f). The sliding carriages can be displaced along parallel guiding tracks (7a-7c), by means of which position and orientation of the platform can be adjusted. Two sliding carriages are running independently of each other on each guiding track, allowing a movement with a total of six degrees of freedom. Since two sliding carriages share one guiding track, the design is simplified and some drive components can be dispensed with.
