Although the principles followed by modern standards for interaction between humans and robots follow the First Law of Robotics popularized in science fiction in the 1960s, the current standards regulating the interaction between humans and robots emphasize the importance of physical safety. However, they are less developed in another key dimension...

Adhesive bonding is a proven alternative to mechanical fasteners for structural assembly, offering lighter and thus more fuel efficient aircraft and cost-effective manufacturing processes. The effective application of bonded structural assemblies is however limited by the tight fit-up requirement, which is with sub-mm tolerance and can be a challen...

Aerospace manufacturing industry is unique in that production typically focuses on high variety and quality but extremely low volume. Manufacturing processes are also sometimes unique and not repeatable and, hence, costly. Production is getting more expensive with the introduction of industrial robots and their cells. This paper describes the devel...

The concept of industrial human-robot collaboration (HRC) is becoming increasingly integrated into manufacturing production lines as a means for enhancing productivity and product quality. However, developments have focused primarily on the technology and, until recently, little research has been geared to understand the key human factors (HF) that...

The concept of industrial human-robot collaboration (HRC) is becoming increasing integrated into production lines as a means for enhancing productivity and product quality. Previous literature suggests that the implementation of any technological change should not merely be seen as an engineering challenge. Inattention to the human element has been...

Conference Paper
Industrial human-robot collaboration has been identified as a promising concept for optimising manufacturing output. One aspect of this concept which can have positive impact on the overall cooperation is the concept of robot to human communication through robot gestures. Although robotic gestures have been investigated for social robots, the impac...

... In this way, the main challenges of industrial robot manufacturers are to find advanced robotic solutions, improving performance continuously in many fields [52,62], such as aviation, aerospace, automobile manufacturing, and service industry [32]. Manipulators have much better position repeatability than accuracy [11,48], such that their repeatability can reach ±0.1 mm B Juan S.

... 18 Some studies have also focused on the suitability of interleaving techniques to improve LVI damage resistance and tolerance. [19][20][21][22][35][36][37][38][39] García-Rodríguez et al. 19 interleaved two types of coPA veils, with identical areal weights and different melting temperatures, between each ply of a quasi-isotropic laminate. They observed that veils that have melted during the composites manufacturing process have reduced LVI damage and enhanced residual strength in CAI tests. ...
... Some subsistent literatures indicated that fiber nonwovens which fabricated by electrospinning technology and dry-laid process toughened continuous CFRPs on Mode-I, Mode-II fracture and Charpyimpact [24][25][26]. The toughening behaviors depended on physical properties (area density, volume fraction, fiber length and fiber orientation) [26][27][28] and materials (CF, PET, PPS, PA and so on) of nonwovens [29], architectures of CF reinforcement [30], and configurations of hybrid composites [27]. For the pure short CF, interface reinforcement between CF and matrix using UV treatment [24], nanoscale core-shell rubber [31,32] and carbon nanotubes [33] contributed to the improvement of toughness. ...
... However, the integrated joint design of the collaborative welding robot AUBO-i10 greatly simplified the complexity of the kinematics calculations. Therefore, choosing this type of robot for welding research is an excellent decision [10]. Due to the RH-20 robot's mechanical structure design, the wrist point can be derived from setting the last joint offset. ...
... The fracture toughness of 4.5 g/m 2 PA66 veil interleaved sample shows an improvement of about 156% and 69% under Mode I and Mode II loadings respectively. Moreover, enhancing IFT relied on energy dissipation, quantitative fiber bridging, and deflection of the crack path along the path was closely related to fiber and matrix distribution around the delamination front [36]. Nevertheless, there has been limited research on the impact of micro-fiber hybridization was reported. ...
... The study of such relationships are sparse for robot arms, and the extent to which findings from mobile robots experiments can be generalized to robot arms is debated [9][10][11]. First, the key psychological constructs will be discussed, with their relevance to increased automation and robotics. ...
... The described problem belongs to the class of two-way coupled FSI problems [34], when mutual influence of fluid and structural components is significant and cannot be neglected. This fact greatly complicates the problem solution and in previous works additional assumptions are often applied allowing one to neglect the two-way character of the interaction [5,24]. ...
... As these systems continue to evolve and be integrated into our daily lives, it is essential to address fundamental ethical issues benefiting customers and companies. The main ethical issues that need to be addressed include the responsibility of companies to provide transparent information about the use of robots in customer service and the protection of customer data [39]. By addressing these ethical issues, companies can build a solid trust-based wall with their customers and maintain an excellent reputation. ...
... The literature encompassing the different organizational changes part of, or following, the introduction of Industry 4.0 technologies has not been sufficiently explored (Charalambous et al., 2017). However, human-centric organizational changes and organizational aspects, such as workforce training, communication, information-sharing, and intra-enterprise collaboration, have been investigated and considered critical success factors for a digital transformation (Moeuf et al., 2019). ...
... Over the past years, researchers have explored the role and impact of organizational factors and measures in the context of introducing cobots across various organizations and sectors. Charalambous et al. [21][22][23] synthesized evidence regarding individual and organizational factors and developed a roadmap for successfully introducing cobots in industries. The roadmap comprises two main propositions: a training program highlighting the robot's key characteristics, such as perceived safety and reliability, to help operators build trust with their robot teammates, and operator empowerment, which is essential as operators gain experience working with the robot, especially during events like robot failures, errors, or deviations. ...
