“…In addition, in the paper of Yumbla et al [17], they presented the mating tolerance needed to reduce the error when a cobot connects a female connector to a male one since many variables can cause the connection not to be effective, such as thicknesses, shapes, etc. In another paper by Yumbla et al [18], they complemented their previous work. In this work, they aligned a wire harness using a vibration plate to connect the male and female connectors and then mount the system to the cobot.…”

The wire harness assembly process is a complicated manufacturing activity, which is becoming more complex because of the evolving nature of mechatronic and electronic products that require more connectors, sensors, controllers, communication networking, etc. Furthermore, the demand for wire harnesses continues to grow in all industries worldwide as the majority of equipment, appliances, machinery, vehicles, etc., are becoming “smart” (i.e., more mechatronic or electronic). Moreover, most of the wire harness assembly process tasks are done manually, and most of these are considered non-ergonomic for human assembly workers. Hence, the wire harness manufacturing industry is faced with the challenge of increasing productivity while improving the occupational health of its human assembly workers. The purpose of this paper is to conduct a literature review exploring the state of the use of collaborative robots in the wire harness assembly process due to their potential to reduce current occupational health problems for human assembly workers and increase the throughput of wire harness assembly lines, and to provide main findings, discussion, and further research directions for collaborative robotics in this application domain. Eleven papers were found in the scientific literature. All papers demonstrated the potential of collaborative robots to improve the productivity of wire harness assembly lines, and two of these in particular on the ergonomics of the wire harness assembly process. None of the papers reviewed presented a cost–benefit or a cycle time analysis to qualitatively and/or quantitatively measure the impact of the incorporation of collaborative robots in the wire harness assembly process. This represents an important area of opportunity for research with relevance to industry. Three papers remark on the importance of the integration of computer vision systems into a collaborative wire harness assembly process to make this more versatile as many types of wire harnesses exist. The literature review findings call for further research and technological developments in support of the wire harness manufacturing industry and its workers in four main categories: (i) Collaborative Robotics and Grippers, (ii) Ergonomics, (iii) Computer Vision Systems, and (iv) Implementation Methodologies.

For robust grasping of workpieces with complex surface geometries such as the plugs of electrical connectors (ECs), individually designed gripper jaws are commonly required. The manual design of the latter is time-consuming, iterative, expensive, and requires expert knowledge. Therefore, automating the design process offers the potential to increase efficiency and reduce costs. However, the plugs of ECs often involve interference contours which pose a high risk for a grasp to fail. Thus, this paper introduces an approach for the automated design of gripper jaws that considers complex surface geometries with interference contours. Thereby, expected geometric uncertainties in the relative pose between a plug and a gripper system can be parameterized by a user. The key steps of our approach are to automatically simulate collision volumes between the gripper jaws and the workpiece to map geometric uncertainties in software for computer-aided design (CAD) and to adapt the gripper jaws accordingly within minutes and without manual design. The results of the experimental validation using three different high-voltage plugs show that the presented approach is suitable for robust grasping of such workpieces. In summary, our work intends to contribute to a more efficient design process of gripper systems for workpieces with complex surface geometries such as plugs of ECs.
