A modular conveying assembly for conveying an object. The graphical program interface includes one or more controls for assigning at least one attribute value to an attribute of an object. For a forward transform equation this may be performed as part of a quantization step and for an inverse transform equation this may be performed as part of a de-quantization step. A rod eccentrically mounted on the gear drives a first portion of the drive member, which in turn causes a second portion of the drive member to drive the abutting member to rotate the axle and upwardly extending arm.
