Withthe implementation of "the Belt and Road Initiative", Chinese companies have accumulated a lot of experience and academic researches after years of development. Compared with domestic ones, overseas projects are confronted with severer risks and challenges due to the complexity of their external environment. With considerable researches start with projects and focus on single projects or portfolio, seldom attention has been paid to overall risk features of international engineering contracting market. In this work, 73 cases of 8 industries are collected from CNKI to analyze risk features of different industries, with categories chosen based on "Annual Report on China international Project Contracting (2017-2018)". Firstly, a thorough identified risks list is established through literature review. Secondly, secondary risk factors of each project are counted as features stand for the industry it belongs. then, SVM method is adopted here to train classifiers for distinguishing risk identities from each other. the existence of risk differences among industries is proved through accuracy. Finally, risk characteristics of transportation projects, electric power construction projects and others are analyzed to provide companies with advices on project risk management in their fields.

Manufacturing processes can be optimized by enabling human-robot collaboration. A relevant goal in this area is to create a collaborative solution in which robots can provide assisting actions to humans, thereby, reducing menial labor as well as increasing productivity. the solution is based on implementing efficient hand-over of mechanical tools from robots to humans. Hand-over tasks are inevitable in human-robot collaborative manufacturing contexts. these tasks need three-step mechanism: object identification, object grasping, and the actual hand-over. this paper presents an approach for robots to find tools for human partners in human-robot collaboration via deep learning. this is achieved using the object detection system YOLOv3 for identification of commonly used mechanical tools. By training on a custom dataset of 800 images of mechanical tools created for the study, the tool recognition is implemented in real-world human-robot hand-over tasks. Experimental results show that the proposed approach achieves a high accuracy for identification of tools in real-world human-robot collaboration. Future work of this study is also discussed.

this paper describes our efforts to develop a Digital Fish Simulator (DFS), particularly aiming at creating a controlled kinematic centered environment to further shed light on how to design and control artificial fish robots. Compared to a 3D simulator for autonomous robotic fish by Liu and Hu, an improved body wave equation capable of multimodal swimming motions is adopted in our simulator and artificial swimming data can be further imported enabling various fictive swimming patterns. Furthermore, the swimming data generated from the simulator can directly be fed into the fish robots for verification, and vice versa. Finally, a series of fishlike robots with different mechanical design have been built to validate our well-formed ideas and to reach a new level of performance close to actual fish for real applications.

this book includes extended and revised versions of a set of selected papers from the Ninthinternationalconference on informatics in control automation and robotics (ICINCO 2012), held in Rome, Italy, from 28 to 31 July 2012. the conference was organized in four simultaneous tracks: Intelligent control Systems and Optimization, robotics and automation, Systems Modeling, Signal Processing and control and Industrial Engineering, Production and Management. ICINCO 2012 received 360 paper submissions, from 58 countries in all continents. From these, after a blind review process, only 40 were accepted as full papers, of which 20 were selected for inclusion in this book, based on the classifications provided by the Program Committee. the selected papers reflect the interdisciplinary nature of the conference as well as the logic equilibrium between the four abovementioned tracks. the diversity of topics is an important feature of this conference, enabling an overall perception of several important scientific and technological trends.

the paper describes the automation of the shoe grinding process using an industrial robot. One of the major problems of flexible automation using industrial robots is how to avoid joint limitations, singular configuration and obstacles. this problem can be solved using kinematically redundant robots. Due to the circular shape of the grinding disc, the robot becomes kinematically redundant. this task redundancy was efficiently handled using Virtual mechanism approach, where the tool is described as a serial mechanism.

It is very common to deploy multi-mobile robots in swarm robotic applications that is targeted for co-ordinated tasks that needs specific formations. the coordination and hence the formations require a good framework of communication, positioning, and controls. Many proposed architectures for indoor systems depend on a camera or another kind of beaconing system for positioning the robots. the paper describes a method using a relative coordinate system without the need for external sensors and is applicable to indoor systems. the initial setup needs the designated global master node and all other nodes to be placed in pre-determined form so that the initial relative distances between the global master and other nodes are known. At the start-up of the system, the configured global master robot node scans and builds the list of all available robot nodes. the global master node will assign the roles of leaders and followers including the global master node itself so that the controls will be distributed. the formation controls are achieved by limiting the communication of the local master to the slaves. Each local master also has the role of a slave to propagate the position with master being the head of the swarm in this chain. the formulated system has been prototyped with generic flow charts and the performance measured show the results to indicate that they can be well utilised in real time system projects.
