Abstract: A part transfer system includes a robotic arm, and an end effector attached to the robotic arm. The end effector includes a locating pin that is operable to engage an existing part feature of a part. The presence of the existing part feature is required for the intended use of the part, and therefore serves a function of the part other than a transfer function. The existing part feature defines a circular aperture disposed on a feature plane. The locating pin includes an engagement portion that extends along a longitudinal axis of the at least one locating pin. The engagement portion includes a diameter that is tapered along the longitudinal axis such that the engagement portion of the locating pin engages a radial inner edge of the circular aperture on the feature plane along an approximately annular contact ring disposed about a circumference of the tapered portion.
