Based on the various problems in the process of coal robot applications, from three-dimensional analysis of the key technology, market demand, and policy regulations and standardization, the paper reviews the use of carbon fiber material, elastic material of traditional surface spraying and integral casting technology to realize lightweight robot, by using the dual redundant design to improve the reliability of the rescue robot CPU, through the functions of voice recognition obstacle sensor, gas sensor acquisition components, and distribution information to realize the underground rescue mission. In addition, virtual test technology, hardware in the loop simulation technology, and shrinkage model technology are proposed to solve the difficulties of hard field testing of rescue robots. These suggest that concrete measures have been pointed out to break the problem of the development of the coal mine relief robot.

Innovation Processes

Für eine marktgerechte Produktentwicklung gibt es in Anlehnung an das Technologie-Reifegradmodell eine Vielzahl von Ansätzen, die den Entwicklungsstand von Technologie und Markt bewerten. Um im Innovationsprozess produktionsstrategische Lücken rechtzeitig aufzuzeigen, müssen Entwicklungsprozesse von Technologie, Markt und Produktion jedoch ganzheitlich betrachtet werden. Hierfür werden unterschiedliche Reifegradmodelle gegenübergestellt, Korrelationen aufgezeigt und erfolgsentscheidende Entwicklungsstufen abgeleitet.   Based on the technology maturity model, there is a variety of approaches describing the maturity of market demand and technology in order to combine technology push and market pull perspectives. However, to be able to show strategic gaps during the innovation process, development processes of technology, market and manufacturing skills have to be viewed holistically. For this purpose, the authors present different degrees of maturity models, show correlations and derive critical fields of action.

Lightweight Structure

Based on the microstructure of the cross-section of the beetle's elytra, a kind of bio-inspiredlightweight structure was designed and made by the carbon fiber material. The compressive andshear mechanical properties of the lightweight structures were studied with finite element method.In addition, quasi-static compression experiments of the structure samples were carried out. Theexperimental results and the finite element analysis results were compared and analyzed, whichproved the effectiveness of the finite element analysis.

Three Dimensional Finite Element

This paper presents field tests performed on a slab-on-girder pre-stressed concrete bridge. The bridge was tested under static loading, crawling loading, and dynamic loading. A full three-dimensional finite element prediction under both static and dynamic loadings was carried out and the results were compared with the field measurements. While acoustic emission (AE) monitoring of bridge structures is not a new vista, the method has not been fully exploited in bridge monitoring. Though numerous quantitative methods have been proposed, they have not yet developed to be useful for actual field tests of bridges. Therefore, in this study, an attempt was made to use the intensity analysis technique for damage quantification using the AE method.

Software startups are increasingly under high pressure to deliver successful products to survive and thrive in the modern highly competitive technology market. Larger organizations with deep pockets can replicate the same business ideas used by startups with relative ease. So how does the average startup stand a chance at succeeding at this seemingly David vs. Goliath contest? This chapter looks at the available literature and identifies factors that can affect the success of software development startups. Using causal loop constructs from the field of system dynamics, the interactions among the various identified factors are visualized to reveal the dynamics of the system. The result is as a three-dimensional view of success factors in form of time, capital, and (product) differentiation. The chapter also explores the cornerstones in the context of the product and business dimensions of software startups. This research acts as groundwork for analyzing the workings of software startups and sets the stage for a more holistic study upon which further research can be carried out.
