Abstract
Linear interpolation is applied to each pair of placement coordinates in a data driven surface mount component placement robot in order to eliminate component misplacement due to board artwork dimensional inaccuracies. The linear interpolation algorithm is derived by measuring the actual dimensions of the artwork of a given board by an integrated vision system via a camera attached to the robot arm.
