Fig. 1 shows a standard robotic tip and an improved tip. A component D which is typically misaligned as shown is to be picked up by a vacuum applied at C to the tips shown. The tip labeled as "Original Tip" frequently fails to pick component weight due to the vacuum not sealing properly when used without rubber A. This "Original Tip," when used with the rubber A, and component centering devices F picks the component more reliably but the centering devices F fail to properly align and position the component with respect to the Tip. This misalignment is due to the resiliency or spring-back of the rubber, as the component centering devices F are actuated; the component is held against the tip by vacuum applied at C; the component is forcibly displaced horizontally and radially to an optimum "aligned" position.
