It has three vertical beams which are the supporting parts of the motion and frame mechanism. The pose of the vertical beams is an error source and has the influence on 3D printing precision and printing quality. The effect of such error source on the 3D precision and quality is random and difficult to be captured by measuring instruments. To reveal the mechanism of 3D printing error caused by the pose of vertical beams, through the simulation of parallel motion mechanism and the derivation of non-ideal parallel printing model, the mechanism of error generation and the influence of error source on 3D printing precision are studied. The simulation results show that the tilted vertical beams can indeed cause the 3D printing error and further affect the 3D printing quality, and that the printing error is related to the size and direction of the rotation angles of the vertical beams.","PeriodicalId":339025,"journal":{"name":"2021 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"440 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116186447","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}

To avoid over-fitting of training, a dropout layer is added to the neural network model. In the post-processing part, two statistical methods are used: majority voting and continuous voting result verification. Finally, a test trial was performed using sEMG signals collected from the human body. The results show that the algorithm can achieve 92.7% recognition accuracy and has good real-time performance.","PeriodicalId":339025,"journal":{"name":"2021 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116253858","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 passive torsional motion increases the contact surface during dynamic gripping.

As is a crucial link, it is the basis of binocular vision technology to obtain the internal parameters of a digital camera. Traditional calibration methods, such as Zhengyou Zhang's method needs a calibration board, while the self-calibration method based on active vision needs to strictly control a camera to move in a designated way. Based on that, those methods can't be applied to simple and convenient occasions. In this paper, we aim to propose a new method of camera self-calibration by improving an existing QPSO algorithm with the EXIF information of digital camera photos. The method only needs to shot one object twice on different angles. We derive the conversion formula of equivalent focal length and pixel focal length and use it to initialize the algorithm. It is to find the optimal solution of the cost function transformed from the Kruppa equation by using the QPSO method. The experiment results proved that the improved method is better than the initial one and using the EXIF information to initialize the algorithm is feasible.","PeriodicalId":339025,"journal":{"name":"2021 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129500341","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}

Previous studies on mobile robots with stair-climbing ability focused on legs and/or crawlers. However, many actuators and complex mechanisms are needed for leg locomotion. In propulsion using crawlers, the contact area is limited by size. Other robots use a wheel called Tri-star wheel for climbing stairs. This wheel enables both stair climbing and moving on flat floors. In this study, we propose a power-assisted carrier cart using the Tri-star wheel to reduce the burden of carrying luggage. The drive unit for the carrier cart has three drive wheels on each side, and the center shaft is connected to each drive wheel in each spoke like a planetary gear. Thus, this wheel can move on a plane and climb stairs by rotating the spoke. A load sensor on the handle measures the pulling force of the user to control motors according to the force. Consequently, the user can move the cart within a constant force regardless of load weight and terrain conditions. Herein, we present the design of the proposed carrier cart, simulation to investigate the power-assist control, and experiments conducted to evaluate the power-assist performance using a prototype.","PeriodicalId":339025,"journal":{"name":"2021 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128602114","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}
