## 1 Introduction
Our aim is to comprehensively examine the evolution of this research field, pinpoint the primary areas and sectors where it is currently applied, elucidate the adopted technological solutions, and emphasize the key benefits attainable through this technology. In this context, we address substantial challenges and opportunities, with a specific focus on hardware and software integration to ensure stable and efficient communication and system adaptation for various scenarios. Our review delves intotelemanipulation and tele-welding scenarios within industrial applications, offering a unique perspective on the integration of XR technology. Notably, our work innovatively summarizes how XR technology can enhance remote welding tasks, providing fresh and valuable insights in this domain. Additionally, our review recognizes the specific challenges encountered in integrating teleoperation systems with diverse hardware platforms and emphasizes the necessity for detailed information on the design of software architectures for interoperability. Through our meticulous analysis, we aspire to contribute significant knowledge to the evolving landscape of XR-enhanced telerobotic systems. The scope of our work is focused on telemanipulation and telemanufacturing tasks in hazardous conditions. To achieve this, we conducted a search for papers published during a seven-year period between 2016 and 2023 in relevant resources for extended reality and robotics, including IEEE Xplore, MDPI, ACM Digital Library, and Science Direct. Additionally, we present and classify the application context of the reviewed articles into two groups: mixed reality-enhanced robotic telemanipulation and mixed reality-enhanced robotic tele-welding. We conducted a thorough literature review focusing on scholarly databases, academic journals, conference proceedings, and reputable online repositories related to the field of extended reality and robotics. Our searches were comprehensive and included keywords such as human-robot interaction, teleoperation, extended reality, virtual reality, mixed reality, and augmented reality and used Boolean operators to refine the search results. We ensured that the selected resources were recent and peer-reviewed, emphasizing studies and articles published within the last 7 years to maintain relevancy and accuracy. This section provides a comprehensive overview of the article's focus on immersive and intuitive telemanipulation frameworks using XR technologies. The rest of the article is structured as follows. Section 2 presents the prerequisites for effective robotic teleoperation, focusing on natural motion retargeting and multimodal feedback. Section 3 outlines the research methodology utilized in the literature and provides initial insights into intuitive and natural teleoperation. Section 4 delves into XR-enhanced telerobotic frameworks for industrial applications and classifies the application context into two groups: MR-enhanced robotic telemanipulation and MR-enhanced robotic tele-welding. Section 5 outlines the challenges and discusses future opportunities in the field of research. Finally, Section 6 summarizes the key findings from the reviewed works and emphasizes the integration of XR, particularly MR, in telemanipulation systems and remote robotic welding.
