A system and method for positioning a sample, or cargo, with respect to a device in a robotic system is provided. The system includes a macro positioning system for "gross" movement of the sample between stations and a micro positioning system for precisely locating the sample in a predetermined location at a station with respect to a device that will interact with the sample. The macro positioning system provides a positioning mechanism for the general movement of a sample along a pathway between various destinations or stations wherein the sample is "grossly" positioned with respect to the station. Once at the station, the micro positioning subsystem disposed between a sample carrier and the station provides a positioning mechanism for "precisely" positioning the sample in a predetermined location at the station with respect to a device that will interact with, or perform some function on, the sample. The system and method provide for multiple sample carrying robots having autonomous navigation thereby providing flexibility and stacker-like queuing for near 100% device utilization.
