    Abstract: A part manufacturing system and a method of manufacturing are provided. The system includes one or more part-moving robots, each having an end effector that grips a part. An operation robot performs an operation on the part while the part-moving robot holds the part. A fixed vision system is located apart from the robots and has at least one fixed vision sensor that senses an absolute location of the part and/or the end effector and generates a fixed vision signal representative of the absolute location. A controller collects the fixed vision signal and compares the absolute location with a predetermined desired location of the part and/or the end effector. The controller sends a repositioning signal to the part-moving robot if the absolute location varies from the predetermined desired location by at least a predetermined threshold, and the part-moving robot is configured to move the part upon receiving the repositioning signal.

    Abstract: Systems and methods are provided for locating a pair of components relative to one another using complex surfaces. One component has a complex surface, where the complex surface is smoothly contoured. Another component is shaped to be connected with the first component. A fixture locates the first component relative to the second component. The fixture includes a locator with a complex surface region shaped to mate with the complex surface of the one component to locate the fixture relative to that component. The fixture includes another locator to locate the fixture relative to the second component.

    Abstract: A system and method of enhanced automated welding of a first workpiece and a second workpiece are provided. The method comprises providing a system for intelligent robot-based welding of the first workpiece and the second workpiece. The method further comprises determining a geometrical location of the first workpiece and the second workpiece to be welded at a welding sequence based a predetermined process variable. The method further comprises adjusting the predetermined process variable based on the geometrical location of the first and second workpieces to define an actual process variable. The method further comprises welding a first portion of the first and second workpieces with the actual process variable to define a first welded portion. The method further comprises determining a weld quality of the first welded portion.

    Abstract: A method of assembling a plurality of subcomponents to form a finished component comprises gripping a first subcomponent with a first end-of-arm tool, wherein the first end-of-arm tool is attached to a first robot arm and grasping a second subcomponent with a second end-of-arm tool, wherein the second end-of-arm tool is attached to a second robot arm. Moving the first and second end-of-arm tools to position the first subcomponent relative to the second subcomponent in a pre-assembly position and then moving the first and second end-of-arm tools to engage interface surfaces of the first and second subcomponents. Forming a joint between the first subcomponent and the second subcomponent with a joining tool attached to a joining robot arm to thereby assemble the finished component.

    Abstract: A component assembly system comprises a first robot arm having a first end-of-arm tool mounted thereon and adapted to grasp a first subcomponent; a second robot arm having a second end of arm tool mounted thereon and adapted to grasp a second subcomponent. A system controller is adapted to control the first and second robot arms and first and second end-of-arm tools to position the first and second subcomponents relative to one another. A first interlocking mechanism is mounted onto the first end-of-arm tool and a second interlocking mechanism is mounted onto the second end-of-arm tool, wherein the first and second interlocking mechanisms engage one another and lock the first end-of-arm tool to the second end-of arm tool, thereby locking the first and second subcomponents into an initial position relative to one another.

    Abstract: A product and an electrical connector assembly includes a first component and a second component. The first component includes a plurality of inner walls spaced from each other to define outer boundaries of respective openings. The first component also includes a first electrical interface. The second component includes a plurality of retention members each having an outer surface and a projection extending from the outer surface of each of the retention members. The outer surface of the retention members is configured to elastically deform along the respective inner walls when inserted into the respective openings such that part of the outer surface of the retention members remains in contact with the respective inner walls when the second component is secured to the first component. The second component also includes a second electrical interface that engages the first electrical interface when the second component is secured to the first component.
