Jumping robots in the existing research suffer from complex mechanical mechanisms and unstable aerial postures, which cause the jumping robot to collide with the ground when landing. This paper proposes the design of a new jumping robot with a large jump stroke based on a simple geared five-bar mechanism. Based on characteristics of the applied mechanism, the proposed jumping robot can realize the adjustment of aerial posture independently. Firstly, a mechanical configuration of the new jumping robot is proposed, and its kinematics and dynamics are given. Then, dimensional parameters of the proposed jumping robot are optimized based on the genetic algorithm. Finally, an experimental prototype is designed to verify the actual performance of the proposed robot. Experimental results show that the proposed jumping robot has a large jumping stroke and stable jumping posture.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128925086","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 that atmospheric density at this height is only 10–11 to 10-9kg/m3, the aerodynamic drag acting on the satellite can be millinewton or even Newton, which is the main reason for the fall of the ultra-low orbit spacecraft. In this paper, the method of aerodynamic drag estimation for the ultra-low orbit spacecraft is given, and the influence factors of aerodynamic drag are analysed, the calculation formula of drag coefficient is emphatically derived, and the influence factors of drag coefficient are studied. The drag coefficients under the conditions of typical orbit and space environment are given. In order to reduce the drag, the SLO spacecraft should be designed as a slender body configuration, and at this time, the drag effect brought by the side cannot be ignored, which should be paid more attention to in the overall configuration and layout design of the spacecraft.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122439863","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}

Because OpenGL technology has the advanced ability of modeling, illumination, transformation and color processing, it can reduce the development cost of pipe bending machine. Therefore, this paper takes 3D pipe fittings as the research object, uses OpenGL technology and Visual C++ programming language to develop a 3D pipe fitting model display system, and realizes the visualization of 3D pipe fitting model. In order to reduce the workload, the model is established by professional 3D modeling software 3DS MAX software, and then rendered and controlled by OpenGL technology.

The visual positioning is easily interfered by light, and the accuracy is limited by the algorithm. Combining the advantages and disadvantages of the two methods, an algorithm combining vision and laser repositioning is proposed. Firstly, vision is based on ORB feature matching to do the preliminary localization, and an artificial bird swarm algorithm is proposed to improve the accuracy of local localization when the prior location is known. The experimental results show that the proposed algorithm shortens the relocation time by one order of magnitude compared with the pure laser localization algorithm, and improves the localization accuracy by one order of magnitude compared with the pure vision algorithm.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121155167","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 training data comes from the ultrasonic simulation signals of cysts and point targets, and the input of DNN is the channel signal and its corresponding wavelet coefficients. DNN divides the parallel input into two types: on-axis signal and off-axis signal, and expects to retain only on-axis signal and clear off-axis scattering. In addition, the performance of DNN beamformer with and without CNR-LOSS is compared, and the effect of loss functions with different CNR weights on image quality is analyzed.
