Abstract
Positioning apparatus to place a reference point at selected locations in a plane. Two carriages are independently mounted to a carriage rail. The rail bears location references and the carriage carry sensors responsive to them to learn their positions along the carriage rail. Guideways and guide rails are mounted in pairs to a respective carriage and to an interface member bearing the reference point. They form an angle between them such that the interface member moves in the plane as a function of the locations of the carriages along the axis and relative to each other. Drivers drive the carriages in response to commands related to the location of the carriages.
