The robot is developing into a software-oriented shape that recognizes the surrounding situation and is given a task. Cloud Robotics Platform is a method to support Service Oriented Architecture shape for robots, and it is a cloud-based method to provide necessary tasks and motion controllers depending on the situation. As it evolves into a humanoid robot, the robot will be used to help humans in generalized daily life according to the three robot principles. Therefore, in addition to robots for specific individuals, robots as public goods that can help all humans depending on the situation will be universal. Therefore, the importance of information security in the Cloud Robotics Computing environment is analyzed to be composed of people, robots, service applications on the cloud that give intelligence to robots, and a cloud bridge that connects robots and clouds. It will become an indispensable element for In this paper, we propose a Security Scheme that can provide security for communication between people, robots, cloud bridges, and cloud systems in the Cloud Robotics Computing environment for intelligent robots, enabling robot services that are safe from hacking and protect personal information.

As the importance of software to society has grown, more and more schools worldwide teach coding basics in the classroom. Despite the rapid spread of coding instruction in grade schools, experience in the classroom is certainly limited because there is a gap between the curriculum and the existing computing environment such as the mobile and cloud computing. We propose an approach to fill this gap by using a mobile environment and the robot on the cloud-based platform for effective teaching. In this paper, we propose an architecture called Cloudboard that enables knowledge sharing and collaboration among knowledge providers in the cloud-based robot platforms. We also describe five representative architectural patterns that are referenced and analyzed to design the Cloudboard architecture. Our early experimental results show that the Cloudboard can be effective in the development of collective robotic systems.

In cloud robotics, the model to share information efficiently is still a research challenge. This paper presents an information sharing model for cloud-enabled robots to collaborate and share intelligence. To provide the efficient message dissemination, an adaptive group communication based on multi-agent is proposed. The proposed algorithm uses a weight function for the link nodes to determine the significant links. The performance evaluation showed that the proposed algorithm produced minimal message overhead and was faster to answer queries because of the significant links compared to traditional group communication methods.

Service robots providing services according to user's needs in dynamically changing environments should be able to utilize external services such as cloud services. Cloud services are, however, changing and expanding continuously and thus the interface to the services must be general and flexible to adapt to the changes of the functionality and data of the services. In order to facilitate the adaptation of the interface to the changes, a model-based general interface to various cloud services is proposed. In this approach, a general and extensible interface is realized by defining standard service profiles that can be easily extended to adapt to the changed services. Experiments with intelligent service robots show satisfying results exhibiting flexible adaptations to new or changed external services.

Various human-friendly robot services have been developed and mobile cloud computing is a real time computing service that allows users to rent IT resources what they want over the internet and has become the new-generation computing paradigm of information society. The enterprises and nations are actively underway of the business process using mobile cloud computing and they are aware of need for implementing mobile cloud computing to their business practice, but it has some week points such as authentication services and distributed processing technologies of big data. Sometimes it is difficult to clarify the objective of cloud computing service. In this study, the vulnerability of authentication services on mobile cloud computing is analyzed and mobile cloud computing model is constructed for efficient and safe business process. We will also be able to study how to process and analyze unstructured data in parallel to this model, so that in the future, providing customized information for individuals may be possible using unstructured data.

빅데이터, 인공지능, 로봇공학, 사물인터넷 등 다양한 정보통신 기술의 융합으로 이루어지는 제4차 산업혁명이 부각과 함께 발생하는 데이터를 안전하게 관리 및 보관하면서 사용할 수 있는 클라우드 플랫폼에 대한 중요성도 같이 증가하고 있다. 그에 따라 신규로 클라우드 플랫폼을 구축하는 곳도 있지만, 기존 인프라를 유지하면서 신규 인프라를 추가하는 형태로 클라우드 플랫폼을 구축하는 경우도 많다. 클라우드 플랫폼을 신규 또는 추가 구축하는 경우 고려해야 할 사항을 인프라 리소스 측면과 클라우드 플랫폼 측면에서 살펴보고자 한다.

In this paper, in Simultaneous localization and mapping (SLAM), the robot acquire its map of environment while simultaneously localizing itself relative to the map. Cloud based SLAM, allows us to optimizing resource and data sharing like map of the environment, which allows us, as one of shared available online map. Doing so, unless we add or remove significant change in our environment, the essence of rebuilding new environmental map are omitted to new mobile robot added to the environment. As result, the requirement of additional sensor are curtailed.

This study focuses on the new teaching assistance robot platform and the cloud-based education service model to support the server. In the client area we would like to use the teacher assistant robot in elementary school classrooms to utilize the language education service platform. Emerging IoT technology will be adopted to provide a comfortable classroom environment and various media interfaces. Extensive precedent review and case study have been conducted to identify basic requirements of proposed service platform. Embedded system and technology for image recognition, speech recognition, autonomous movement, display, touch screen, IR sensor, GPS, and temperature-humidity sensor were extensively investigated to complete the service. Key findings of this paper are optimized service platform with cloud server system and possibilities of potential smart classroom with intelligent robot by adopting IoT and BIM technology.

LiDAR는 조사된 빛이 피사체에 반사되어 돌아오는 시간을 측정하여 거리를 측정하는 장비로서, 넓은 영역과 긴 거리에 걸쳐 실세계의 정밀한 3차원 정보를 포인트 클라우드 데이터로 제공해 준다. 이러한 대용량 포인트 클라우드 데이터는 자율주행 자동차, 로봇, 3차원 지도 제작 등 컴퓨터 비전 기술을 이용하는 다양한 분야에 널리 활용될 수 있다. 그러나 유리 구조물을 포함하는 피사체를 LiDAR로 촬영하는 경우, 유리면에서 빛의 반사로 인한 가상의 포인트가 생성되어 실제 3차원 정보를 왜곡하는 문제가 있다. 포인트 클라우드의 후속 처리를 효율적으로 수행하기 위하여, 이러한 왜곡을 제거하는 전처리 기술이 필요하다. 본 고에서는 LiDAR의 취득 원리와 3차원 포인트 클라우드의 특성을 고찰하고, 유리 반사로 인한 왜곡된 가상의 포인트를 자동으로 검출하고 제거하는 새로운 연구 주제를 소개한다.
