A robotic system includes end-effector(s) that combine a plurality of objects in a production process. The system includes sensor(s) that obtain measurement(s) relating to a combination of a first object and one or more other objects during the production process. The system includes a control system communicatively coupled to the sensor(s). The control system stores specifications relating to the combination of the plurality of objects. The control system receives the measurement(s) from the sensor(s), determines a difference based on the measurement(s) and the specifications, determines adjustment(s) to the production process based on the determined difference, and sends, for the end-effector(s), instruction(s) based on the specifications and the one or more adjustment(s). The end-effector(s) combine a second object with the first object and the one or more objects based on the specifications and the one or more adjustment(s).
