Abstract
An end effector for a robotic welder includes a plurality of component-receiving reservoirs that receive components that are to be welded to a work surface of base structure. A stripper plate rotates to move a component from one of the component-receiving reservoirs to a deployed position. A central actuator is controlled to clamp the component into frictional engagement with the work surface. A welding head performs a tack weld and the central actuator is retracted, out of engagement with the component. The welding head then welds the tack welded component to the work surface.
