First, in order to reduce the randomness of the traditional RRT* path search, adding the node gravitational field function could reduce the generation of redundant nodes, thereby improving the path convergence rate; Secondly, in order to change the folding problem in the traditional RRT* algorithm path, the B-spline function was imported to smooth the planned path, which could reduce the vibration of the joint axis and prolong the service life of the robotic arm. Simulations in MATLAB showed that the average planning time of the improved RRT* algorithm was shortened by 76%, the average path distance was shortened by 14%, and the total number of nodes was reduced by 31.9%. After improving the algorithm, the lines convergence quickly and the line -seeking efficiency is high. The algorithm has good feasibility and effectiveness, and has reference value for the planning of robotic arm path.","PeriodicalId":165439,"journal":{"name":"2022 5th International Conference on Robotics, Control and Automation Engineering (RCAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129668678","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}

First, an environment recognition architecture is constructed based on convolutional neural networks to classify the images acquired in different environments. Then, the images in different environments are enhanced separately using an image enhancement algorithm. Finally, the enhanced images under different environments are trained based on the YOLOX detection algorithm to achieve real-time detection of the images, and the NUSCENES dataset is used for experimental evaluation. The results show that the proposed detection method improves the average accuracy AP for target detection in sunny, rainy, cloudy and night environments by 6.5%, 13.56%, 6.52% and 6.82%, respectively, improving the detection of small targets.","PeriodicalId":165439,"journal":{"name":"2022 5th International Conference on Robotics, Control and Automation Engineering (RCAE)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126063071","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}

Specifically, we establish potential field to guide the stretch direction of branches and extract the key points of the final planned path for optimization. For the lack of intelligence of the artificial potential field method, the sampling method gets improvements both on that and rapidity. In the same way, the artificial potential field method also makes up for the lack of planned path's smoothness with the sampling method. Aiming at the complicated structure of the transporting system, we set strict safety constraints to ensure the success of obstacle avoidance. In addition, an algorithm of searching along the wall is proposed to fit in the scene with unknown information obstacles. The methods' feasibility and effectiveness are verified by simulation results and relevant comparative analyses.","PeriodicalId":165439,"journal":{"name":"2022 5th International Conference on Robotics, Control and Automation Engineering (RCAE)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128571149","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}

Then, the grid size is greatly reduced by using boundary layer meshing technology. Finally, the temperature field and flow field distribution of the fluid in the heat exchanger are obtained by finite element calculation. The results show that, on the one hand, the condensate temperature is in a local overheating state and the oil flow rate is too low, and there is a retention zone; on the other hand, the temperature in the overheating region decreases with the increase of the shell flow rate. Therefore, the coupling effect of condensate oil retention and local overheating may accelerate the corrosion rate of heat exchanger tube bundle. It is suggested to adjust the operation parameters of the heat exchanger and optimize the internal structure to make the internal flow rate and temperature distribution more reasonable, so as to improve the service safety and reliability of the heat exchanger.","PeriodicalId":165439,"journal":{"name":"2022 5th International Conference on Robotics, Control and Automation Engineering (RCAE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131685084","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}
