The development of legged robots and robotic systems must consider high dynamics and wide bandwidth. Due to their large bandwidth, electro-hydraulic servo-valves (EHSV) provide a substantial advantage over traditional electro-hydraulic proportional valves. However, some EHSVs' electrical properties can make it difficult to function correctly. To enhance the dynamic performance of EHSV-based actuation systems, this research suggests a novel electronic driver topology. The hydraulic, electrical, and mechanical components of the Simscape a toolbox in Matlab-Simulink is used to verify the theoretical study that forms the basis of the proposed driver design. Finally, experimental data from a hydraulic system test bench in a lab are acquired.","PeriodicalId":134487,"journal":{"name":"International Journal of Modeling and Optimization","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131845824","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 model which assumes mass action incidence, is analyzed qualitatively to determine the stability of their equilibria.

If realized, these robots will help save space in factories and increase production efficiency. However, this requires high positioning accuracy of the robot. In this study, we analyze the motion accuracy of industrial robots and their compensation method to construct this system. Here, we use a laser tracker to measure the coordinates of the hand tip of the robot when the robot is stationary. Subsequently, the error amount in an arbitrary posture is predicted using a Gaussian process. Furthermore, Bayesian optimization is used to efficiently search for points where the positioning error norm is likely to be large, which is then compensated for by a feedback method. This method successfully reduced the time cost of the experiment to approximately one-tenth of that required in the previous study and achieved a correction of approximately 66 %. However, because this method alone does not perform an exhaustive measurement, it is unclear whether all the points predicted to have small errors are so small that they do not require correction. Therefore, future studies, we will aim to verify this issue by considering the time efficiency.","PeriodicalId":134487,"journal":{"name":"International Journal of Modeling and Optimization","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116355898","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, this criterion alone may place an unnecessarily large load on a robot joints. On the other hand, developments in IoT technology have facilitated the acquisition of servo information from robots and other devices. This information is expected to become increasingly important in the future. In this study, two small multi-joint robots are used to propose a method to determine robot placement based on criteria different from the robot working range. The proposed method is constructed by focusing on the joint torque working on the robot, which can be easily obtained using IoT technology. In addition, focusing on the torque margin and operating force ellipsoid derived from manipulability, we examine the cooperation of two robots to lift a weight that exceeds the range of motion of a single robot exerting a constant external force.","PeriodicalId":134487,"journal":{"name":"International Journal of Modeling and Optimization","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126670847","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 ensemble learning brings together various weak learners to create strong learners. Based on this ensemble learning idea, we develop a model for an efficient smoke detection tool. The three schemes of ensemble learning are investigated including bagging, boosting, and stacking. The bagging ensemble algorithm studied in this research is Random Forest and the boosting algorithm is AdaBoost. The stacking ensemble adopts three algorithms, that are Random Forest, AdaBoost, and Logistic Regression. The other learning algorithms adopted for performance comparison include Support Vector Machine, Naïve Bayes, and Decision Tree. The smoke detection data contain 62,630 records and 15 features. The dataset has been separated into training set and test set with a ratio of 75:25.
