- Wire harnesses are vital for any modern automotive vehicle. They control the basic functions in a vehicle, for example, windshield wipers and critical functions such as sensors, cameras, and autopilot functions. Thus, the quality of wire harness assembly is highly important. Today, wire harnesses are usually assembled manually, which creates unergonomic and tedious working conditions for operators. Traditional and collaborative industrial robots have been identified as possible solutions to overcome challenges faced by operators in this type of assembly. The international research community has proposed many solutions for automating the assembly of wire harnesses in automotive vehicles but despite these solutions, the industry has not been able to adopt a method to automate this assembly process fully or partially. This paper presents a review of findings on robot-assisted wire harness assembly processes based on a systematic literature review. Specifically, the assembly of wire harnesses in Electric Vehicles (EVs). The state-of-the-art review focuses on solutions to improve unergonomic work situations and ensure the quality of assembly operations. Best practices and reasons for the lack of extensive implementation in automotive final assembly systems are described. Further, the paper presents suggestions based on success stories where the automation of the wire harness assembly in automotive vehicles has been realised by leveraging human-centred automation solutions. Based on the findings, this paper identifies the research for future study. The findings also indicate that there is already technology that can support the automation of wire harness assembly processes in EVs but it is crucial to identify the human aspects and the role of humans in the assembly of wire harness assembly process.

- In the current automotive industry, human operators perform wire harness assembly manually, which causes significant quality, productivity, safety, and ergonomic problems. Robotic assembly is a critical facilitator in addressing these problems. However, it remains challenging to implement for robotizing the assembly of wire harnesses. Wire harness assembly is a specific scenario of deformable linear object manipulation. Robotizing this assembly task demands robots to flexibly adapt their actions to the dynamically changing industrial environment based on robotic perception results. Existing research suggested the significance of robotic visual perception in the robotic assembly of wire harnesses. Implementing computer vision techniques is fundamental to enabling robots’ visual perception capabilities. Nonetheless, the industry has yet to introduce vision–based solutions to robotize wire harness assembly fully or partially. Through a systematic literature review, this article identifies fifteen scientific publications in vision–based robotized wire harness assembly. The results show various computer vision applications regarding wire harness components and assembly operations studied in previous research. Nevertheless, this article recognizes two significant challenges for computer vision applications in robotized wire harness assembly: (1) fulfilling production requirements on robustness and practicality and (2) exploiting the intrinsic physical features of wire harnesses for visual recognition. This article also advocated five prospective research directions toward more efficient and practical vision-based robotized wire harness assembly: (1) developing learning-based vision systems to exploit intrinsic features and multi–modality data of wire harnesses; (2) adapting vision systems proposed for robotizing assembly operations in manufacturing wire harnesses; (3) assessing the practicality, robustness, reliability, and sustainability of vision systems; (4) inquiring vision–based human–robot collaboration; and (5) exploring new product designs for facilitating visual recognition.

- Wire harnesses are essential hardware for electronic systems in modern automotive vehicles. With a shift in the automotive industry towards electrification and autonomous driving, more and more automotive electronics are responsible for energy transmission and safety-critical functions such as maneuvering, driver assistance, and safety system. This paradigm shift places more demand on automotive wire harnesses from the safety perspective and stresses the greater importance of high-quality wire harness assembly in vehicles. However, most of the current operations of wire harness assembly are still performed manually by skilled workers, and some of the manual processes are problematic in terms of quality control and ergonomics. There is also a persistent demand in the industry to increase competitiveness and gain market share. Hence, assuring assembly quality while improving ergonomics and optimizing labor costs is desired. Robotized assembly, accomplished by robots or in human-robot collaboration, is a key enabler for fulfilling the increasingly demanding quality and safety as it enables more replicable, transparent, and comprehensible processes than completely manual operations. However, robotized assembly of wire harnesses is challenging in practical environments due to the flexibility of the deformable objects, though many preliminary automation solutions have been proposed under simplified industrial configurations. Previous research efforts have proposed the use of computer vision technology to facilitate robotized automation of wire harness assembly, enabling the robots to better perceive and manipulate the flexible wire harness. This article presents an overview of computer vision technology proposed for robotized wire harness assembly and derives research gaps that require further study to facilitate a more practical robotized assembly of wire harnesses.
