We propose a human-robot interaction(HRI) platform based on motion capture and mapping. Platform consists of capture, processing/mapping, and action parts. A motion capture sensor, computer, and avatar and/or physical robots are selected as capture, processing/mapping, and action part(s), respectively. Case studies-an interactive presentation and LEGO robot car are presented to show the design and implementation process of Kinect based HRI platform.

본 논문은 일체형 플랫폼 디바이스인 ATMEGA-128을 이용하여 추적하는 이동로봇에 대해 서술한다. 최근 하드웨어의 개발로 일체형 플랫폼 디바이스들이 많이 개발되고 있다. 또한 디바이스와 센서 등을 접목한 여러 가지 제품들이 만들어 지고 있다. 본 논문에서는 일체형 플랫폼 디바이스중 하나인 ATMEGA 및 초음파 장비를 활용한 이동로봇의 설계 및 구현에 대해 서술한다. 초음파 장비의 발신부는 마이크로폰을 이용하여 초음파를 발생시키고 이동로봇에 부착된 수신부에서는 마이크로폰으로부터 초음파 신호를 수신 대기 한다. 이후, 수신 감도의 정확성 향상을 위해 초음파 신호를 증폭시켜 값을 판단 한다. 해당 신호를 통해 이동로봇은 초음파 신호 발신부와 수신부 사이의 거리 값을 알아낸다. 이후 가장 가까운 거리 값을 나타내는 방향을 로봇의 전면부가 되게 회전하고 직진하여 최종적으로 로봇은 발신부 방향으로 이동하게 된다.

인간이 하기 힘들거나 번거로운 작업은 지능형 로봇이 대체하고 있다. 하지만 로봇을 개발하기 위해서 설계, 구현 단계에서 실제 로봇을 사용하기 어려워 시뮬레이션 환경이 많이 사용된다. 실제 로봇을 사용할 경우 시간과 비용이 많이 들며 개발에 실패하거나 문제가 생겼을 경우 위험부담이 크다. 그러므로 위험부담을 줄이고 개발기간을 단축하기 위해서 실제 구성될 환경과 동작 환경을 고려한 시뮬레이션 환경이 로봇 제어 프로그램 개발에 많이 사용되고 있다. Pyro는 교육과 개발의 용도로 많이 사용되고 있으며, 로봇에 대한 세부적인 지식이 없더라도 제어 프로그램을 충분히 구현할 수 있어 시뮬레이션 환경으로 적합한 로봇 개발 플랫폼이다. 본 논문에서는 Pyro에 대해서 알아보고 Pyro 플랫폼들을 비교해본다.

Various types of robots are being utilized in the construction industry. Particularly, there is high interest in robots that can be applied to plastering automation, which can ensure consistent work quality. In this paper, we propose a robot platform based on wheels for plastering automation. Through experiments, we measured the surface pressure according to the air pressure of the wheel using the designed robot. As a result, we were able to confirm that the designed robot could perform plastering work on soft mortar with uniformly low pressure per wheel.

The platform concept has been used for business operations in various forms: product platforms, transaction platforms and industry platforms. All these platforms have common characteristics of having 'core' that is reused frequently and 'peripherals' that are less reusable and changed often. Companies use platforms to enable efficient development and creation of product family, transactions and innovation. These platforms provide new opportunities for many small and medium-sized companies (SMEs) by bringing changes to traditional industrial structures focused on the products rather than platforms. The service robotics industry in South Korea is mainly composed of technology-intensive SMEs due to its small market size. Although these SMEs succeed in developing technologies, they have difficulties creating and expanding markets to sell products. Thus, this study addresses the characteristics and problems of the South Korean service robotics industry and analyses how ROBOPRINT, one of the SMEs in the service robotics industry, successfully creates and continuously expands the service robot market by adopting platform concept. The results indicate that ROBOPRINT has been applying two types of platforms: product and transaction platforms. First, ROBOPRINT created art robots that were apartment mural service robots. Rather than selling art robots, the company developed various robots such as painting robots, building exterior wall-cleaning robots by reusing the core technology of the robots. The company also developed various robots according to the buyers request. In addition, the company used the robots to directly provide apartment mural services for customers. This mural service has been extended into various areas, not only in apartments but also in soundproof walls, underground passages, and retaining walls. Besides, ROBOPRINT added new services continuously by developing technologies such as virtual reality. Second, ROBOPRINT mediated mural service buyers and mural designers. This platform reduced buyers' workload, which necessitates requesting mural services to ROBOPRINT and searching for mural designers. For designers, this opened up new opportunities to participate in the mural business. The platform attracted both mural buyers and designers who were scattered before. Finally, ROBOPRINT seeks to expand the platform's scope to outside company. To share internally reused ROBOPRINT's technology with other companies, the company participated in Daegu city's 'New Technology Platform Industry'. Furthermore, ROBOPRINT is trying to share the service platform by leasing robots to other companies. This allows external agents to develop technologies and provide services by reusing resources from ROBOPRINT. This study contributes to existing theories by showing that SMEs continuously create and expand markets by building various platforms. Moreover, it provides useful implications for practitioners by describing the firm's specific platform-building strategy.

With the recent advent of the Fourth Industrial Revolution, the importance of the platform business is increasing. Most global companies with high market value are known as platform companies. This change is changing the business model of companies in various industries. However, existing studies have mainly focused on information-intensive industries and large companies. Therefore, this study attempted to analyze the case of Everybot, which is successfully growing in the service robot industry. Everybot is known as a company that produces robot cleaners. However, according to the result, the company has focused on developing autonomous driving technologies and pursuing platform-based business strategies rather than product-based ones. The results of this study have theoretical and practical implications by showing how domestic small and medium-sized robot companies apply platform-based business strategies to achieve long-term growth with gaining leadership in the personal service robotics market.

The robot has been widely applied to all parts for the improvement of the life quality of human beings. It is expected that the parts industry for robots is rapidly growing to one of the majority of the future robot industry. The electronic components of robots are connected to the central processing unit and an organic part of a robot system. The central processing unit must be controlled to operate more efficiently by configuring some control systems of the robot. In this paper, we propose a new platform model that centralizes several parts of a robot through the CAN based communication system and simplifies their connection structure.

According to abrupt decrese in number of farmer and ageing society, there has been a need for development of low cost agricultural robot. In this paper, a H/W and S/W platform of caterpillar type agricultural chemical dusting robot based on XP embedded system were described. The developed agricultural robot has 2 d.o.f caterpillar type driving wheel and 2 d.o.f chemical dusting spray mechanical system. The H/W platform of the agricultural robot consists of robot controller, remote controller and sensor controller. In S/W platform, 5 processes work concurrently, which are task manager, TCP-IP communication process, localization process, wheel control, and sensor control process. This robot platform has been developed for chemical dusting robot. We proved this system's validity through field test.
