1. An end-of-arm-tool (EOAT) mechanical interface for operatively coupling a gripper actuator to a part-gripping device, the EOAT mechanical interface comprising:
first and second EOAT-to-gripper interface bodies moveable relative to each other along a gripping axis, each of the first and second EOAT-to-gripper interface bodies being mountable to, respectively, first and second portions of the gripper actuator that is configured to actuate the first and second EOAT-to-gripper interface bodies along the gripping axis;
a lateral restraint dovetail joint surface configured to contact and slide relative to a confronting lateral restraint dovetail joint surface of the part-gripping device in response to actuation of the first and second EOAT-to-gripper interface bodies, thereby pulling the part-gripping device inward toward the EOAT mechanical interface; and
a matable alignment structure configured to limit a gripping axis distance that the gripper actuator opens when engaging the EOAT mechanical interface with the part-gripping device such that the lateral restraint dovetail joint surface becomes aligned for engagement with the confronting lateral restraint dovetail joint surface.
