We present a robotic crack filling system that can effectively and efficiently deliver fluidic repairing materials to fill surface cracks. Motion planning and cracking filling control are the two main tasks presented in this paper. We present a graph-based crack coverage (GCC) algorithm to solve motion planning problem. The filling motion control is captured by a model predictive control (MPC) scheme given the mobile platform trajectory. We also develop a crack-filling robotic prototype. Simulation and experimental results are presented to demonstrate the system design and performance evaluation.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122885248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In traditional intelligent tool wear monitoring methods, features used to indicate tool wear always vary with cutting conditions and hence not applicable in cutting condition-varying cases. In this paper, a cutting condition robust milling tool wear monitoring method is proposed. In the method, the irregularity of cutting force is measured by fractal dimension and then utilized to indicate the tool wear level. Experiments of tool wear monitoring are conducted for high speed CNC manufacturing. The simulation results show that the proposed fractal dimension of cutting force is capable to indicate tool wear level and robust to cutting conditions.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"59 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132532718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multicopter is equipped with sensing technology to monitor the quality of the air, thus, presenting itself as a portable and easy-to-position in 3-dimensional environments alternative to high-cost static monitoring stations. Aside from the design considerations regarded to allow the aircraft to fly at high altitudes, a methodology is presented to describe the process concerning air quality data acquisition. This work features an analysis of the performance of the hexacopter by scrutinizing data from flight tests held at high-altitude and sea level locations and an analysis of results from the values obtained by the drone's low-cost sensors, which are compared against the data obtained from professional equipment certified by the EPA (Environmental Protection Agency of United States) from SENAMHI, the local regulatory entity in Peru.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132543343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on detection of occupancy of elevator car in the video scenes in oblique views. We propose an occupancy detection method fusing analysis of dual synchronous videos captured by two cameras installed inside and outside the elevator, respectively. One video is used to detect the absolute value of occupancy by the duration of full opening state of the elevator door. The other video is used to solve the coefficient of the occupancy by the change of foreground areas before and after the elevator door is opened. The absolute value and the coefficient jointly determines occupancy measurement. The experimental result verifies the effectiveness of our method and the correctness reaches up to 91.7%, exceeding that of the traditional method based on pixel statistics in the connected area. This method may contribute to the elevator control system after it is integrated with the video surveillance system.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133344544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

System fault has become an increasingly significant threat to the reliability and fault tolerance of automation systems. Redundancy of components within the system is one popular method for enhancing fault tolerance. One of the simple and effective methods for fault tolerance that has stood the test of time is Triple Modular Redundancy, which provides not one redundant copy of a critical system component, but two extra copies for a total of three. Ironically, providing three copies of a sensor, for example, only provides tolerance to one failure. It takes four copies to provide resilience to a double-point failure, but this can be expensive in terms of the cost of sensors and installation, wiring, and interface circuitry. We propose Quadruple Adaptive Redundancy, a new method that adds software-based estimation techniques, rather than additional hardware components, to achieve higher levels of robustness with virtually no incremental cost. In this paper, the performance of Quadruple Adaptive Redundancy is verified through computer simulations and compared to Triple Modular Redundancy with one and two induced sensor failures.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133766237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic concept, several error measures and variations of the algorithm have been around in the literature for two decades now, but never showed significant impact on widely used slicing software. Users of our early test implementations reported two major drawbacks of the existing approaches: the control measures are not intuitively usable and the resulting height distribution in many cases is not optimal for an object, requiring extensive post-editing. In this paper, we propose a more intuitive control measure and implementation based on the volumetric surface error and a subsequent manual refinement of layer heights by manipulating an interpolated height-curve. We describe the efficient computation of adaptive layers by analyzing the model surface over the full layer height. All implementations are available as ready-to-use open source software.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133926018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, we propose an improved version of GR, which is denoted as IGR, for the situation of adopting the utopian point as the reference point in MOEA/D.

According to the VDC principle, the entire system is conceptually divided into such subsystems: the object, the space base, the manipulator, the reaction wheel and the massless virtual manipulator. The last term is designed to solve the nonholonomic constraints of the whole system. Based on the mathematical model of the entire system, kinematics and dynamics of every subsystem from the object to the space base are analyzed. A virtual decomposition controller of each subsystem is simultaneously designed, and this controller and the corresponding subsystem structure a control subsystem of the whole robot. All subsystem controllers constitute the controller of the entire robot system, and the combination of this controller and the robot system is the virtual decomposition control system of this robot. Then it takes two steps to achieve its stability analysis — the virtual stability of each control subsystem and the stability analysis of the whole control system. Finally, the VDC system of the free-flying space robot with an object is simulated. Simulation results show that the VDC system is stable and effective.","PeriodicalId":445441,"journal":{"name":"2017 13th IEEE Conference on Automation Science and Engineering (CASE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132365182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
