1. A method comprising:
generating, by a management system, one or more surface profiles, which defines a reference bead shape of a reference bead of a liquid adhesive and at least one reference process parameter, based on measurement data including a plurality of reference bead shapes of the liquid adhesive and a plurality of selected reference process parameters used to produce respective reference bead shapes of the plurality of reference bead shapes;
controlling, using at least one process parameter, a robot within a manufacturing environment to dispense a first bead of a liquid adhesive onto a surface of a substrate, the first bead having a first bead shape based on the at least one process parameter;
measuring, by a portable measuring device positioned within the manufacturing environment, at least one characteristic of the first bead shape;
accessing, with a processor of the portable measuring device, one or more response surface profiles of the liquid adhesive defining a reference bead shape of a reference bead of the liquid adhesive and at least one reference process parameter;
comparing, by the processor, the measured first bead shape to the reference bead shape; and
responsive to determining the first bead shape is different than the reference bead shape, determining, by the processor, based on the at least one reference process parameter, at least one updated process parameter, wherein the at least one updated process parameter is configured to cause the robot to dispense a second bead having a second bead shape, and wherein the updated process parameter is selected such that the second bead shape is closer to the reference bead shape than the first bead shape.
