All-optical network can directly process signal in the optical domain with the conventional optical - electrical - optical conversion and improve the signal processing speed. All-optical multicast technology is an important part of all-optical networks, which can improve the flexibility of the network and make better use of network resources. In this paper, four kinds of nonlinear effects are investigated to realize all-optical multicast, including cross-gain modulation (XGM), cross-phase modulation (XPM), four-wave mixing (FWM) and cascaded sum frequency generation (SFG)/difference frequency generation (DFG). The principle and multicast performance of these nonlinear effects are discussed. Moreover, the characteristics of several kinds of nonlinear devices are also compared, including SOA, HNLF, PPLN.","PeriodicalId":293925,"journal":{"name":"2021 the 3rd International Conference on Robotics Systems and Automation Engineering (RSAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134641030","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 system develops a unique model applying low-cost technology; furthermore, the use and interaction of this system with the user, through a web platform, are easy. The model was carried out by analyzing the different devices on the market that have the characteristic of sending and receiving data in the cloud. The ESP8266 device was used in this project, as it has all the necessary features at a reduced price. This device receives information from the sensors so that the development board sends an SMS through the IFTTT application, which takes 2 seconds to reach the user's cell phone and the fire department, providing them with the link to the web platform that shows the real data. The system performed successfully against testing in a real environment.","PeriodicalId":293925,"journal":{"name":"2021 the 3rd International Conference on Robotics Systems and Automation Engineering (RSAE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114391210","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}

Next, the control system of the robot is described, which is mainly divided into positioning, vision, gripping structure, and multi-task drive control. Moreover, this paper also experimentally verifies the positioning recognition and stereo matching of the vision control part. The experiments prove that such a general computer vision system can be applied to the designed robots. Possible directions for the development of this home service robot are also proposed.","PeriodicalId":293925,"journal":{"name":"2021 the 3rd International Conference on Robotics Systems and Automation Engineering (RSAE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117255966","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}
