It is necessary to study accurate measurement and characterization techniques for residual stress. The LCR (Longitudinal critically refracted) wave method has the characteristics of non-destructiveness, high efficiency and accuracy, and has high application value in industrial stress detection. In the LCR wave method, the sound path and the thickness of the tested sample will affect the time-of-flight obtained by the subsequent cross-correlation algorithm, resulting in inaccurate final stress detection values. In this paper, the ultrasonic nondestructive testing system is used to detect the sound path of different sizes and the thickness of the tested sample, and the sound path range and the thickness range of the tested sample for the LCR wave method are obtained. The obtained experimental results promote the development of non-destructive testing technology.","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":"115229357","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}

Stroke has three characteristics: high morbidity, high mortality, and high disability rate. At present, stroke has become one of the main causes of human death, and the population suffering from a stroke in China is gradually becoming younger, many patients can not work and live normally, destroying many happy families. However, stroke is not invincible. Once suffering from stroke, patients can still live and work independently as long as they actively carry out rehabilitation training. The surface EMG signal contains abundant physiological information and has remarkable effects on nerve rehabilitation and orthopedic rehabilitation. Patients with rehabilitation training less training can not play a rehabilitation effect, and excessive training is easy cause secondary injuries, therefore, this paper will design a fatigue state classification system based on surface EMG signals of human lower limb muscles, and analyze the fatigue state of patients’ lower limbs by collecting surface EMG signals of target muscles of human lower limbs, to ensure that patients can not only carry out effective training but also not cause secondary injuries due to excessive training.","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":"115240396","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}

Lobster farmers are often faced with tasks such as observation, feeding, and fishing, which are all done manually, with low efficiency and high operating costs. Therefore, this paper proposes a real-time underwater lobster detector based on Generative Adversarial Networks and Convolutional Neural Networks, implemented by a spherical amphibious robot. Firstly, the underwater lobster image dataset is established, and the improved GAN algorithm and data increment method are used for data enhancement preprocessing. Secondly, the single-shot multi-frame detector (SSD) is improved as follows, using the lightweight network MobileNetV2 as the backbone of the SSD network; in the network prediction layer, using depthwise separable convolution instead of standard convolution to accelerate inference; compressing the fully connected layer The parameters construct a lightweight model. Finally, the model is trained on the underwater lobster dataset and deployed on a spherical amphibious robot, and the changes in the loss function value during training before and after image enhancement and algorithm improvement are plotted. Two sets of experimental test results show that the model optimizes the target recognition accuracy of underwater lobsters, and the recognition accuracy reaches 90.32%. The reduced model size facilitates model deployment and is only 24MB in size. The model has good stability and high recognition accuracy in identifying lobsters in complex situations.","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":"115312293","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}
