## 1 Introduction
### Background  
The study of human interaction with artificial agents has become increasingly important for understanding the nuances of Human-Robot Interaction (HRI). Central to this field is the concept of \"embodiment\" in artificial agents, which significantly influences user perception and engagement. [PERSON] et al. [4] noted that the physical manifestation of these agents plays a crucial role in shaping how humans interact with and perceive them. Over the past decade, extensive research has focused on categorizing and understanding these various embodiments. [PERSON] [7] offers valuable insights into this area, showing how people's experiences and cognitive responses vary between virtual and physical embodiments of interactive agents. Beyond the type of embodiment, its degree and design collectively shape human perception and interaction dynamics.  
Furthering this discourse, [PERSON] et al. [8] suggest that people may find it easier to share private or sensitive information with a robot rather than a human, due to the robot's perceived neutrality. This insight raises important questions about the potential roles of robots in settings where confidentiality or discretion is essential.  
In recent years, the integration of robotics across diverse sectors has marked a significant evolution in our relationship with technology. [PERSON] [6] emphasizes the transformative impact of this integration on HRI, noting that it has facilitated substantial advancements in both technology and interaction models. [PERSON] et al. [18] further elaborate on this shift, discussing the rise of specialized robots designed for specific tasks and environments. This specialization is reflected in the development of social humanoid robots like Pepper [13] and telepresence robots like Double 3 [19]. These robots represent a paradigm shift in creating interactive, user-centered solutions that seamlessly blend digital and physical realms, as envisioned by [PERSON] [20].  
Pepper and Double 3 stand out for their capabilities and applications, serving as examples of recent technological progress. Pepper, with its humanoid appearance and interactive features, has been adopted in customer service [17], healthcare [21], and education [22]. Similarly, Double 3, equipped with telepresence capabilities, is transforming remote workplace interactions [23], enabling new possibilities for bridging geographical distances.  
The primary aim of this study is to investigate how users interact with two distinct types of social and telepresence robots--Pepper, a social humanoid robot, and Double 3, a telepresence robot. Furthermore, the research aims to understand how the design and functionality of these robots influence user perception, interaction patterns, and emotional responses. Additionally, the study seeks to identify key factors that contribute to user experience and satisfaction with these robots, considering their specific technological capabilities and limitations. The study also examines participants' perspectives on integrating such robots into everyday environments.  
The central research question guiding this study is: How do users perceive and interact with these social and telepresence robots, and what are the implications of these interactions for user experience, technological expectations, and social dynamics?The specific research questions explored in this study are:  
1. What common experiences and reactions do participants have when interacting with each type of robot?
2. What unique experiences and reactions do participants exhibit when interacting with each type of robot?
3. What specific challenges or areas for improvement can be identified to enhance the user experience with these social and telepresence robots?  
The following sections will describe the Pepper and Double 3 robots in detail, focusing on their design, functionality, and impact in diverse interaction settings.
