Abstract: Large-scale wires and cables (W&Cs) are the nerves of large and complex electromechanical products vital to their regular operation. The laying process of W&C has been highly dependent on manual work and urgently needs intelligent guidance like augmented reality (AR). However, model registration and occlusion handling based on AR for large-scale W&C laying scenes cannot achieve high-quality results to date because of the lack of texture, the local field of vision, and other characteristics. Therefore, a markerless AR guidance method for large-scale W&C laying is proposed to address this long-lasting problem. First, camera, ultrawideband, and inertial measurement unit sensors are integrated to coarsely register the W&C models based on coordinate transformation and mapping virtual and physical spaces. Then, a local edge matching method is used to register the W&C models based on the coarse one finely. Next, the occlusion relationships of the W&C models are handled based on assembly constraints; the models are anchored in the simultaneous localization and mapping map for visual and continuous guidance. A locomotive W&C laying case study and evaluation results show that this method meets industrial application requirements regarding efficiency, accuracy, and robustness and has several advantages compared to other methods, including extra-large scale, automatic registration, and virtual-real fusion.

Abstract: Industry 5.0 aims at establishing an inclusive, smart and sustainable production process that encourages human creativity and expertise by leveraging enhanced automation and machine intelligence. Collaborative robotics, or "cobotics",is a major enabling technology of Industry 5.0, which aspires at improving human dexterity by elevating robots to extensions of human capabilities and, ultimately, even as team members. A pivotal element that has the potential to operate as an interface for the teaming aspiration of Industry 5.0 is the adoption of novel technologies such as virtual reality (VR), augmented reality (AR), mixed reality (MR) and haptics, together known as "augmentation". Industry 5.0 also benefit from Digital Twins (DTs), which are digital representations of a physical assets that serves as their counterpart - or twins. Another essential component of Industry 5.0 is artificial intelligence (AI), which has the potential to create a more intelligent and efficient manufacturing process. In this study, a systematic review of the state of the art is presented to explore the synergies between cobots, DTs, augmentation, and Industry 5.0 for smart manufacturing. To the best of the author's knowledge, this is the first attempt in the literature to provide a comprehensive review of the synergies between the various components of Industry 5.0. This work aims at increasing the global efforts to realize the large variety of application possibilities offered by Industry 5.0 and to provide an up-to-date reference as a stepping-stone for new research and development within this field.

Recently, NASA astronauts have applied the HoloLens AR headset to many scenarios on the International Space Station. In addition to the previously announced treadmill maintenance, it has also been used recently to maintain the Cold Atom Laboratory. It is reported that this is the first time astronauts have used AR assistance to repair scientific experimental equipment. In the future, this technology is expected to be used for remote upgrades of the Cold Atom Laboratory, eliminating the need to transport it back to Earth.

Virtual reality (VR) is a computer simulation system that allows for the creation and experience of virtual worlds, while augmented reality (AR) technology is a technique that skillfully integrates virtual information with the real world. Generated virtual information such as text, images, 3D models, music, videos, etc., are simulated and applied to the real world, with the two types of information complementing each other, thus "enhancing" the real world.
