A positioning system comprises at least one carriage 1 supported by toothed wheels 2 and 4 engaging with surfaces 3 and 5 which may have grooves therein. The carriage is magnetically connected through the surface 3 to a second carriage 6 upon which tools or a pick and place mechanism may be located (Fig 5). The carriages may be provided with three wheels (Fig 5) and may carry tools, materials or material containers. A multi level surface (Fig 6, 31, 33 and 34) may be provided and the surface may move vertically via leadscrews 35 that may also act to supply power to carriages 36. The carriages may be fitted with electromagnetic or suction cup pick and place devices and may move around a product 32 as it is being printed or assembled. Components may be selected from adjacent pigeonhole storage means or cartridges 29 that may hold material deposition tools 30. In further inventions a three dimensional (3D) printer or a food processor may be provided. |
