In fact, collaborative robotics foresees the possibility that humans and robots share the same workspace, so the safety of the human operators must be ensured. The collision avoidance algorithm here presented can modify the trajectory of the robot in order to avoid any collisions with a human operator. A fundamental element for the algorithm is the relative position between robot and human. In this work, the information of the position of a human operator is obtained by Microsoft Kinect sensor in the form of a point cloud. Two Microsoft Kinect are used and their point cloud data is merged to overcome the problems related to the possible occlusions of the sensors, obtaining a more reliable point cloud. Each Kinect works with a dedicated PC and the two PCs communicate via ethernet network in a master-slave mode. The layout of the acquiring system is described and the functions used for the communication between the PCs and the manipulation of the point clouds are presented. Results of simulation tests made to verify the performances of the system and collision avoidance based on point cloud compared with convex mesh are reported and discussed.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117299117","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}

An extended state observer (ESO) is employed for estimating not only the external disturbance but also the unmeasured states in order to improve the accuracy of the closed-loop system. When the barrier Lyapunov function is used to develop the proposed control with the ESO, the output constraints of the robotic manipulator are overcome. Finally, some simulations of the proposed control are conducted on a 3-DOF manipulator to verify the effectiveness of the proposed control with the presence of unknown frictions, external disturbance, and the time-varying output constraints.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"45 4-5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116507322","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 study aims at the sensitivity analysis of the environmental vibrations when the operating conditions of the machine vary and at the identification of the principal causes of excitation. Methods: numerous experimental tests have been carried out on a dedicated test bench and on a complete machine with sixteen stations. For a filling station the load cell signal and the acceleration of the plate that supports the bottle have been acquired and studied. A one-degree of freedom model with varying mass has been implemented in a dedicated software in Delphi language for the vibration modelling. Results: a detailed sensitivity analysis has been developed. The model has allowed a deeper understanding of the phenomena that occur. It also showed the potentiality to be used for the vibration prediction in a compensation process.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114208814","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 hydraulic simulation model is designed using SimulationX to verify the hydraulic power performance of dual arm's operation. Flow rate is analysis by joint velocity of the Work Machine. We also performed instrument and hydraulic simulation simultaneously to determine the operating angle and the response frequency of each joint on the work machine. Next, we simulated the positioning of the accumulator to increase the accuracy of the simulation model and to apply the PID controller and compensate the pressure. Finally, we verified the accuracy of the analytical model by comparing the simulation result with the real system test result. This evaluates the hydraulic characteristics of the 7DOF dual arm joint motion and the accuracy of the simulation model.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114936556","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}

Single- and multi-objective optimizations are employed to maximize the output torque and/or minimize the torque ripple for an IPMSM with four-step linear rotor skew. The motor model is based on look-up tables. The rotor skew angle vector is optimized for priority operating points in both constant-torque and constant-power regions of the torque-speed map. It is found that the output torque and torque ripple can be balanced to meet the targets of the output torque quality and the voltage constraint. Both two- and three-dimensional finite element analyses are used to verify the optimized results.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114728153","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 order to get high quality image correction, FSMs need to have large apertures, high responsivity and multiple degrees of freedom control. In this paper, we propose a FSM that has a large-diameter mirror driven by four voice coil motors and is supported by a compact magnetic suspension system enabling it to have fast response and long-range movement not only in the tip-tilt directions but also in the axial directions. A prototype FSM with an 80 mm diameter dummy mirror was built. The mirror is supported by a magnetic suspension system having six degrees of freedom. The suspended mirror is controlled by the VCMs and the driving ranges in the axial and tip-tilt directions are ±500 µm and ±20 mrad, respectively. Furthermore, the servo bandwidths achieved in the tip-tilt directions are more than 1kHz.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133843509","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}

Particularly in the case for air leak testing for small volumes, such as the application of cooling systems for battery modules in packs for automotive use. Accuracy of the test is key in identifying good parts from bad parts. With this volume and application, the external factors must be heavily controlled in order to maintain consistency, so automation becomes an attractive method to control this. Not only this, but using Industry 4.0 technology such as Industrial Internet of Things, IIoT, the operator and engineer can be empowered with data, not only from the results, but of the test equipment and environment itself. This creates opportunities for the data to be fed back into the process upstream and downstream. This paper explores the automation of this application, and how the visibility of the data can inform downstream and support processes, recommending a model to implement that could be scaled to similar applications.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122318482","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}
