Abstract
A basic idea of the present application is that in case of determining a position of the object on the surface, it is possible to also use transport mechanisms for the transport of the object on the surface which leads to less reproducible transport movements as the regulation may be executed directly on the basis of the observed movement as compared to the desired movement. Embodiments using compressed air, magnetism and/or bending waves are described.
Claims29
An object for a controllable transport on an air cushion, comprising:
- a level bottom;
- and
- a plurality of recesses in the level bottom, wherein at least a predetermined one of the recesses is adjacent to a side wall of the object and in the side wall an opening is formed through which air of the air cushion may escape laterally from the at least one predetermined recess.
A system for transporting an object on an air cushion, comprising:
- a plurality of nozzles in a level surface which are controllable separately from each other in order to let compressed air stream out which forms an air cushion between the object and the level surface;
- a determiner for determining a position of the object on the level surface;
- and
- a controller for controlling the nozzles depending on the determined position.
A system, comprising:
- a plurality of nozzles in a level surface through which compressed air may be guided;
- an object for a controllable transport on an air cushion generated by the compressed air, comprising
- a level bottom;
- a plurality of recesses in the level bottom, wherein at least one predetermined one of the recesses is adjacent to a side wall of the object and in the side wall an opening is formed through which air of the air cushion may escape laterally from the at least one predetermined recess;
- and
- a controllable unit for selectively closing and opening the opening;
- and
- a determiner for determining a position of the object on the level surface;
- and
- a controller for controlling the controllable unit for selectively closing and opening the opening in order to approximate the object to a desired position on the level surface.
A system for moving an object which may be magnetically attracted or repelled across a surface, comprising
- a plurality of magnetic coils distributed along the surface controllable separately from each other in order to generate magnetic dipoles with an alignment perpendicular to the surface;
- a determiner for determining a position of the object on the surface;
- a controller for controlling the plurality of magnetic coils distributed along the surface in order to approximate the object to a desired position on the surface.
A method for transporting an object on an air cushion by means of a plurality of nozzles in a level surface which may be controlled separately from each other in order to let compressed air stream out forming an air cushion between the object and the level surface, the method comprising:
- determining a position of the object on the level surface;
- and
- controlling the nozzles depending on the determined position.
A method for transporting an object by means of an air cushion generated by the compressed air and a plurality of nozzles in a level surface through which compressed air may be guided, wherein the object comprises a level bottom and a plurality of recesses in the level bottom, wherein at least a predetermined one of the recesses is adjacent to a side wall of the object and an opening is formed in the side wall through which the air of the air cushion may escape laterally from the at least one predetermined recess, the method comprising:
- determining a position of the object on the level surface;
- and
- selectively closing and opening the opening depending on the determined position in order to approximate the object to a desired position on the level surface.
A method for moving an object which may be magnetically attracted or repelled across a surface by means of a plurality of magnetic coils distributed along the surface which may be controlled separately from each other in order to generate magnetic dipoles with an alignment perpendicular to the surface, the method comprising:
- determining a position of the object on the surface;
- and
- controlling the plurality of magnetic coils distributed along the surface in order to approximate the object to a desired position on the surface.
