Abstract

The present invention relates to a system for identifying the position of a machine in a fixed frame of reference, said machine standing on an essentially plane support surface. In the invention, the support surface is fitted with a plurality of interactive integrated bushings, each bushing being fitted with emitter means serving to emit a predetermined code enabling the bushing concerned to be identified and thus making it possible to deduce the coordinates of a point associated with said support surface, and the three-dimensional machine is fitted with at least one articulated arm terminating in a position sensor, said arm being fitted with receiver means capable of detecting the code emitted by a bushing amongst the plurality of bushings when the associated position sensor is brought into contact therewith.
