A labware transport apparatus includes a frame, defining a labware space, and a robotic multi-link arm operably connected to the frame via a drive section. The arm has a predetermined link configuration determining a minimum footprint of the arm and a corresponding maximum reach of an end effector of the robotic multi-link arm within a range of motion of the end effector. The range of motion, at least in part of the labware space, of the end effector is delimited by a blockage of a substantially vertical axis of motion, of the drive section of the robotic multi-link arm, extending through the range of motion, wherein the blockage is sized and shaped based on and so as to maximize the range of motion of the end effector of the robotic multi-link arm having the predetermined link configuration that is common determining the minimum foot print and the corresponding maximum reach.
