1. A system for robotic accuracy enhancement comprising;
- at least one robotic device adaptable for multi-axial movement and presenting an arm having an end of arm tool having a central axis for performing various operations on a workpiece;
a plurality of multi-axial devices for generating light beams oriented relative to at least one said robotic device; and
a plurality of removable target elements connected to said end of arm tool with each of said target elements being pre-certified to orient said end of arm tool relative to the workpiece in 6 Degrees of Freedom (6-DOF) to perform various operations on the workpiece as each of said target elements is activated by said multi-axial devices.

Abstract
The inventive concept of the metrology system (the system) actively determines the 6 Degree of Freedom (6-DOF) pose of a motion device such as, but not limited to, an industrial robot employing an end of arm tool (EOAT). A concept of the system includes using laser pointing devices without any inherent ranging capability in conjunction with the EOAT-mounted targets to actively determine the pose of the EOAT at distinct work positions of at least one motion device.

7. A system for robotic accuracy enhancement comprising;
-
a plurality of robotic devices adaptable for multi-axial movement and presenting an arm having an end of arm tool having a central axis for performing at least one operation on a workpiece at a first period of time; a plurality of multi-axial devices for projecting light beams oriented relative to said robotic device; a plurality of removable target elements connected to said end of arm tool of each said robotic device, with each of said target elements being pre-certified to orient said end of arm tool relative to the workpiece to perform operation on the workpiece as each of said target elements is activated by said multi-axial devices; and a controller operably communicated with said target elements, said plurality of multi-axial devices, and said plurality of robotic devices for manipulating at least one said multi-axial device to activate at least one said target element within a second period of time less than the first period of time, thereby guiding at least one other of said robotic devices. - View Dependent Claims (8, 9, 10, 11)
