First, a small depth-of-field visual system of a few microns is formed using a zoom microscope lens and a high magnification objective lens, which is moved equidistantly along the longitudinal direction to acquire image sequences of the local surface of the silicon sphere. Then, each image sequence is preprocessed to remove some of the blurred interfering images. Finally, the sharpness of the image sequence is calculated. In the first step, the sharpness of the image sequence is calculated by various methods; in the second step, the sharpness data are analyzed and counted to find the location of the sharpest image, and the height of the location is acquired by a Z-axis translation stage with a longitudinal grating ruler to obtain the height of the local area on the surface of the microstructure corresponding to the sharpest image. The experimental results show that the accurate sharpest image in the image sequence can be obtained by using the method in this paper, and the retrieval accuracy reaches 99.40%, which is obviously better than the existing sharpness methods.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117158393","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 view of the object - oriented simplicity, this paper uses robot cluster to avoid multiple obstacles. Artificial potential field algorithm is widely used in the field of robot obstacle avoidance because of its simple structure, small amount of computation and good real-time performance. But in actual use in the artificial potential field algorithm has certain defects, mainly includes the target unreachable problem and local minimum value problems, by improving the traditional artificial potential field algorithm, this study so as to improve the artificial potential field algorithm when use the deficiencies, in order to improve the artificial potential field algorithm when the mobile robot to round up the target of obstacle avoidance. Finally, the simulation results show that the improved artificial potential field method can solve the problems of local minimum and unreachable target, and has good dynamic obstacle avoidance ability. This method ensures the reliability of spherical robot group and improves the efficiency of multi-robot group.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129716958","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 output stiffness of the VSA is excepted to be independently controllable during the rehabilitation training processing. Furthermore, the motion and stiffness control of VSA can be independently controlled by VSA for rehabilitation application scenario. In this paper, a hybrid motion stiffness control strategy for achieving assist-as-needed control and suitable patient-robot interaction was proposed utilizing the compliance characteristic of VSA. The elbow joint output stiffness could be adjusted by a linear mapping method to obtain controllable assistant level, which is based on the real-time bilateral position tracking error. It is noted that the linear mapping scaler could be regulated for different patient injury-levels. The preliminary experimental results show that the proposed method can adjust the elbow joint stiffness for patients according to the real-time bilateral position errors.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128641602","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}

On this basis, a two dimensional optimization model is established with saturated magnetic induction intensity and current density as optimization variables. Genetic algorithm has certain advantages in solving nonlinear multiobjective optimization problems. In this paper, NSGA-II algorithm is used to optimize the design of high frequency transformers with ferrite, amorphous alloy and nanocrystalline core materials. By comparing the optimization parameters of the simulation results, the superiority of nanocrystalline materials in the design of high frequency transformer is verified, due to its high saturation magnetic induction strength and high permeability, nanocrystalline materials have better comprehensive performance than ferrite and amorphous alloy materials in high-frequency and high power applications.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116195862","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}
