## 2 Systematic Literature Review
### Summary and Analysis of Selected Articles  
In this section, the most relevant articles for the topic under study are analyzed. Table 2 shows the identified articles. This table was created to analyze the contributions of each study, based on an exhaustive search in academic databases. The selected articles were thoroughly reviewed and analyzed to identify recurring themes related to Industry 5.0. These themes were systematically organized into a structured table, where columns represent distinct categories and rows correspond to individual articles, with markings indicating coverage of each theme. From this analysis, several critical insights emerge. Industry 5.0 is fundamentally characterized by a human-centric approach, where technology is designed to enhance human capabilities rather than replace them. This principle is supported by fluid human-machine collaboration, ensuring that automation complements human decision-making \begin{table}

Additionally, sustainability is embedded throughout the entire life cycle of solutions--from initial design to implementation--reinforcing the need for environmentally and socially responsible innovation. Another key structural element is the use of intuitive interfaces and feedback loops, which ensure continuous adaptation based on human input. At the foundational level, Robotic Process Automation (RPA) primarily handles repetitive, rule-based tasks. However, the reviewed studies revealed a significant gap: none demonstrated meaningful integration with AI or Industry 5.0 principles. This suggests that RPA, while useful for basic automation, must evolve into a more intelligent framework to support advanced Industry 5.0 applications. Collaborative and Explainable AI (XAI) plays a pivotal role in bridging this gap. Its applications focus on shared decision-making, particularly in adaptive systems where human oversight remains essential. A strong emphasis is placed on transparency and explainability, ensuring that AI-driven processes are interpretable and trustworthy. This is particularly crucial in human-machine interfaces, where clarity and accountability foster seamless cooperation. The transition from Industry 4.0 to 5.0 follows a model of progressive technological integration, where iterative advancements lead to more cohesive and adaptive industrial ecosystems. However, this evolution faces several challenges, including cultural resistance to change, a lack of interoperability standards, data security risks, and the need for continuous workforce upskilling. These barriers must be addressed to facilitate widespread adoption.
