Medical service robots are variously defined and classified by researchers and related government departments, but surgical robots and rehabilitation robots are commonly included in medical service robots, and except for these, the robots are classified as other medical service robots. In this study, domestic and foreign development trends and use cases were considered, focusing on logistics, guidance, and drug processing robots among other medical service robots. Logistics and guidance robots were developed quite a lot in Korea and completed a pilot project, or are being commercialized in hospitals, and exported. However, although the drug prcocessing robots was developed in Korea, the robot being use in the hospital was an imported. In order to expand and activate the robot market, systematic follow-up studies such as demand prediction studies are needed.

The development of IT technology makes the functions and services of robots be integrated, and thus the robots become more intelligent and useful. As sophisticated usage of robots has evolved, direct communication by human language is necessary to increase the efficiency of their usage. In this paper, we propose a conversational interface platform for integrated service robots using MS Robotics Studio. The proposed platform consists of three types of components: a conversation manager to control the flows of the integrated service robots, a user interface to interact with users, and multiple service robots to perform actions or services. For a test-bed of the proposed platform, we build a schedule manager system and confirm the usability through SUS subject test by comparing the schedule manager system with MS Outlook.

Building on Technology Readiness and Acceptance Model(TRAM), the study aimed to examine how technology readiness affects consumers' perceptions of ease of use, usefulness, and risk, which in turn predict their intention to use retail service robots. Specifically, the study proposed that technology readiness motivators (optimism and innovativeness) would influence perceived ease of use and usefulness, while technology readiness inhibitors (discomfort and insecurity) would affect perceived risk. The study further examined if the perception factors (ease of use, usefulness, and risk) contribute to intention to use retail service robots. A survey method was used with data collected from Korean consumers. The final sample size was 418. The data was analyzed using structural equation modeling. Findings of the study revealed that technology readiness motivators positively affected perceived ease of use and usefulness while innovativeness had no impact on usefulness. All the inhibitors increased perceived risk. Lastly, as hypothesized, perceptions of ease of use, usefulness, and risk predicted intention to use retail service robots. This study extended the retail technology literature by applying and validating TRAM to the context of consumer acceptance of retail service robots. The study further helped marketers and retailers by highlighting the importance of technology readiness in improving consumer perceptions and responses towards retail service robots.

This paper proposes a new paradigm for cooperation of multi-robot system for home service. For localization of each robot. the master robot collects information of location of each robot based on communication of RFID tag on the floor and RFID reader attached on the bottom of the robot. The Master robot communicates with slave robots via wireless LAN to check the motion of robots and command to them based on the information from slave robots. The operator may send command to slave robots based on the HRI(Human-Robot Interaction) screened on masted robot using information from slave robots. The cooperation of multiple robots will enhance the performance comparing with single robot.

As the fourth industrial revolution has progressed globally, computing education is progressing centered on robots. However, pre-service teachers' attitudes toward robots were negative in previous studies. In order to solve this problem, this study analyzed the difference in the attitude of the pre-service teachers to the robot according to the factors. The subjects of this study were 309 pre-service teachers attending K university. In order to measure the attitude of the pre-service teacher to the robot, the negative attitude measure for the robot was used. And, in order to measure the attitude of the pre-service teachers to the robots, negative attitude measurement scale was used. As a result, pre-service teachers showed different attitudes toward robots according to gender, experience of robot manipulation, and experiences of robot-related lectures. Especially, when the gender was male than female, and the experience of robot manipulation and the experiences of robot-related lectures, the attitude of pre-service teachers to robot was positive.

In recent years, motivated by the emergence of ubiquitous computing technologies, a new class of networked robots, ubiquitous robots, has been introduced. The Ubiquitous Robotic Companion (URC) is our conceptual vision of ubiquitous service robots that provide users with the services they need, anytime and anywhere in ubiquitous computing environments. To realize the vision of URC, one of the essential requirements for robotic systems is to support ubiquity of services: that is, a robot service must be always available even though there are changes in the service environments. Specifically robotic systems need to be automatically interoperable with sensors and devices in current service environments, rather than statically preprogrammed for them. In this paper, the design and implementation of a semantic-based ubiquitous robotic space (SemanticURS) is presented. SemanticURS enables automated integration of networked robots into ubiquitous computing environments exploiting Semantic Web Services and AI-based planning technologies.

Technology and tourism have become inseparable, and technological innovations propose new services to the tourism industry. During the current pandemic, service robot usage has increased more than at any other time which comes with advantages and disadvantages. This paper discusses the opportunities and challenges of utilizing service robots in the service industry during and after the pandemic crisis. The study follows a content analysis methodology. Findings indicate that service robots are easy to access, offer an alternative form of communication, reduce costs and boost operational safety; in contrast, robotics increase unemployment and cause anxiety and depression among the demoralized employees.

Many service robots which is interacting with human at home and in buildings have been developed. Few of them are shown in of the United States and of Japan. These robots are supposed to have a powerful indoor navigation performance in places where human beings live and work. The overall capability of service robots to move around in this environment is called environment correspondence, in which localization problem to find the accurate position and orientation is the most critical problem. While users set up a proper or a best environment for industrial robots, but for services robots at home and in buildings, it is very difficult to change the environment for robots. The expanded workspace due to mobility is difficult to be covered by means of those used for industrial robots because the cost increases and human beings do not want their environment to be changed for robots. This fact has made many researchers study efficient and effective environment correspondence problems. Among these problems, localization is the most difficult. Goal of localization study includes (1) Accurate detection of position and orientation (2) Minimum cost of the additional devices (3) Minimum change of human environment. In this study, as a solution of the above, we propose "Artificial Stars" which are attached on room ceiling as landmarks. In addition, we solve an adoption problem raised when a robot is delivered to a customer site and before it can perform its full navigation capability. We call this as "Initialization Problem" of service robots. We solve the initialization problem for both cases of environment with the map and without map. The proposed system is experimented and has shown how well it handles the initialization problem.

The robot imitates humans and recognizes the external environment and judges the situation. The robot is a machine that operates autonomously. Robots are divided into manufacturing robots and service robots. Service robots are classified as professional service robots and personal service robots. Because of the intensified competition of productivity in manufacturing industries, rising safety issues, low birth rate and aging, the robots industry is emerging. Recently, the robot industry is a complex of advanced technology fields, and it is attracting attention as a new industry where innovation potential and growth potential are promising. IT, BT, and NT related elements are fused and implemented, and the ripple effect is very large. Due to changes in social structure and life patterns, social interest in life extension and health is increasing. There is much interest in the medical field. Now the artificial intelligence (AI) industry is growing rapidly. It is necessary to secure global competitiveness through strengthening cooperation between large and small companies. We must combine R&D investment capability and marketing capability, which are advantages of large corporations, and robotic technology. We need to establish a cooperative model and secure global competitiveness through M&A.

Social robots are attracting attention as an alternative to social problems in modern society, and the need for modularization has been raised to efficiently manage various robots. The study aims to reestablish the concept of 'Personal social service robot' and propose a new modularization method to apply it. For this study, literature research about the definition of social robots and service robots is conducted. In addition, we investigated the modularization of robots and analyzed the modularization cases of service robots. Based on this, we have deducted considerations for applying social service robot modularization and proposed a new modularization. This study divided the module into active module and passive module according to whether it is electric or electronic component of the module, and the active module was again classified into basic module and additional module according to the basic and replacement type of the robot. The modularization was verified by making the prototype of the actual robot.
