Abstract: A robotic module comprising a housing having opposed first and second sides, and comprising a base, a first end comprising a first drive feature on one of the first and second sides, and a second end comprising a second drive feature on one of the first and second sides. A first rotatable hub is mounted on the first end of the housing and comprises a third drive feature on the side of the housing opposite the side of the first drive feature. A second rotatable hub is mounted on the second end of the housing and comprises a fourth drive feature on the side of the housing opposite the side of the second drive feature. The robotic module is further comprised of a coupling for synchronously rotating the first and second rotatable hubs. A first robotic module may be engaged with a second robotic module to form a robot.

Abstract: The slide handler is an instrument that automatically transfers glass microscope slides from a cassette or magazine to a motorized microscope stage and then returns the slide back into the second cassette. The use of this instrument permits the unattended computer control, measurement and inspection of specimens mounted to the slides. Full modular integration of the system components allows for the slide handler instrument to be utilized with any microscope. The instrument system has a minimum of three components; namely a slide cassette indexer, an XY-stage, and a slide exchange arm. The indexer, the arm and the XY-stage are connected together and integrated into one unitary modular instrument that can be moved from one microscope to another.
