Sensor device for intuitively manipulating the heavy material-handling robot
As the conditions of working environment at the construction site cannot be typified, intelligence of robot system is considered to be the best solution for a lack of uniformity and homogeneity such as various kinds of unexpected situations or conditions. Precise finishing quality of robot system, pre-fabrication system of construction materials, and undisturbed material circulation system also remains unsolved problems, up to now. Human-robot cooperation technology based applications have been come up for several decades to combine the human's advanced neural system with robot's enhanced physical performance. This study proposes the newly-designed sensor device for intuitively manipulating the heavy material-handling robot system through the analysis of conventional method. And the feasibility of virtual coordinate generation algorithm and performance evaluation of the proposed system is verified through the experiments and field-test.
Construction Robots: The Search for New Building Technology in Japan
This book presents Japan's achievements in the development and application of over 100 construction robots and five automated systems. The Japanese have progressed far beyond the U.S. in these new technologies, which are already having a revolutionary impact on Japanese architecture. The impact of robotics has already begun to show measured improvements in quality, productivity, and safety in construction.
Semiautomated quantification of the fibrous tissue response to complex three-dimensional filamentous scaffolds using digital image analysis.
Fibrosis represents a relevant response to the implantation of biomaterials, which occurs not only at the tissue-material interface (fibrotic encapsulation) but also within the void fraction of complex three-dimensional (3D) biomaterial constructions (fibrotic ingrowth). Usual evaluation of the biocompatibility mostly depicts fibrosis at the interface of the biomaterial using semiquantitative scores. Here, the relations between encapsulation and infiltrating fibrotic growth are poorly represented. Virtual pathology and digital image analysis provide new strategies to assess fibrosis in a more differentiated way. In this study, we adopted a method previously used to quantify fibrosis in visceral organs to the quantification of fibrosis to 3D biomaterials. In a proof-of-concept study, we transferred the "Collagen Proportionate Area" (CPA) analysis from hepatology to the field of biomaterials. As one task of an experimental animal study, we used CPA analysis to quantify the fibrotic ingrowth into a filamentous scaffold after subcutaneous implantation. We were able to demonstrate that the application of the CPA analysis is well suited as an additional fibrosis evaluation strategy for new biomaterial constructions. The CPA method can contribute to a better understanding of the fibrotic interactions between 3D scaffolds and the host tissue responses.
