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":"37 1","pages":"0"},"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}

A novel skip connection method is adopted to change the way information flows, which incorporating multi-scale feature information. This enables us to obtain more common features of encoding and decoding layers. Low-level detail features and high-level location features are exactly the semantic information we need. We argue that these semantic information plays an important role in the model’s learning of colorization tasks. When there is as much similar semantic information as possible from the decoder and encoder networks, the network will handle easier learning tasks. The proposed model architecture is evaluated on a large dataset for gray image colorization. Experimental results show that our model improve the coloring performance.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116797462","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}

Although this approach can produce collision-free paths, its performance cannot be guaranteed in dynamic, human-centered environments. The reason for this is that more factors need to be considered, including people’s perceptions, than simply ensuring that one gets from one place to another without colliding with an obstacle. Therefore, the ideal map should be able to manage various types of semantic information in a flexible manner, in addition to tracking obstacles. We propose a multi-group map based on a multi-layer map, which is characterized by allowing the layers to store multiple types of information and be flexibly combined to produce multiple sub-maps that can provide references for semantic navigation. The proposed map has been evaluated through simulation to determine its potential to contribute to the creation of semantic navigation behaviors.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116938025","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 control the underwater robot accurately, it is very important to study the hydrodynamic characteristics of the robot. In this paper, the hydrodynamic characteristics about two kinds of underwater robots (spherical and fish-shaped robot) are studied according the application. Firstly, the hydrodynamic characteristics of the two shapes are studied by the qualitative analysis of velocity field and pressure field. Then, by changing the speed and volume of the robot, the drag resistance force of the robot is further quantitatively analyzed. These obtained characteristics can be used to guide the application of flow rate sensing and pressure sensing on underwater robots.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114845096","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 heat dissipation power of the robot is determined by empirical formula and robot energy consumption. The thermal model of SCARA robots was established by using the finite element method in COMSOL, and the steady-state temperature and heat dissipation path of SCARA robots were obtained by solving the finite element model. It was concluded that the temperature at axis Jl of a SCARA robot was the highest, and the temperature diffused in the center of axis Jl. The effect of surface convection velocity on the steady-state temperature of SCARA robots is studied. The results show that the increase of surface convection velocity can effectively reduce the temperature of the robot at high temperature.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124148656","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}

However, the number of point features is insufficient in the low-texture environments, so the performance of these SLAM systems will be significantly reduced. In this research, a PLISLAM system that integrates point features, line features and Inertial Measurement Unit (IMU) is proposed to implement high-precision positioning and mapping for dynamic vehicles. Specifically, a state-of-the-art SLAM scheme ORBSLAM3 is built at first. Then, its theoretical formulation is derived step by step to handle the environmental line features and the Bundle Adjustment (BA) is integrated to optimize the data.

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.
