Weld seam detection is a key technology in robotic welding which is usually performed using a visual system. In most existing vision-based approaches, traditional image processings are used to obtain weld seams. Generally, these approaches are sensitive to their surrounding environment, especially illumination. Therefore, we address the problem by introducing the visual attention mechanism of the primate. Firstly, image preprocessing is executed to block visual interferences. Secondly, a visual saliency model based on local contrast is proposed to emphasize weld seam candidates. Finally, some basic image processings are performed to extract the desired weld seam. In order to validate the proposed approach, experiments are carried out in different cases: two types of joints (butt and fillet joint) and three types of shapes (straight line, zigzag and curve). The results demonstrate that this method is effective and robust, and is useful for autonomous welding robots.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124737786","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}

As a ride-on device, the system offers high mobility and is able to move forwards, backwards, and sidewards as well as automatically recognize and overcome obstacles. Furthermore, the telescopic motion of the legs enables the handling of steps, stairs, and low clearances.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125601339","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 overcome these problems, various types of robots are to be developed and verified by demonstration tasks using standard software. If many developers use the standard software to develop robots, the possibility to find a killer application of the robots will be increased and the service robot market will be widespread. Thus, we developed a prototype of a robot photographer using Robotics Technology Middleware to activate the community. The robot was developed quickly and easily. However, the success rate for capturing pictures was low in various environments. Therefore, we analyzed the cause of failures and proposed a correction algorithm. To improve the robot performance, we developed a multiple human detection system with recovery motion.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121982812","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 agricultural machinery is chosen as the experimental object of the method. There are 4 health level, such as failure, hazardous, sub-healthy and healthy. Some data of different provinces have been obtained, the health level can be acquired by RBF neural networks. The mathematical model of agricultural machinery is difficult to be proposed in this paper, so the traditional control algorithm can't be used in agricultural machinery. However, the RBF neural networks can solve this problem. At the same time, some vital factors should be considered, such as mileages, rotational speed, stubble height, water temperature, oil pressure of agricultural machinery. The rotational speed and stubble height have a big effect on fault prediction of agriculture. The experimental results verify the effectiveness of the proposed method.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121470891","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}

A nanorobotic manipulation system with multiple positioning degrees of freedom (DOFs) was used for the real time nanomanipulation. The nanorobotic manipulation system was constructed inside the scanning electron microscopy (SEM) specimen chamber to pick up MWCNT from MWCNT bulk without any other bounding except van der Waals force and measure the electrical properties of MWCNT and MWCNT/Cu hybrid nanowire. The electron beam was focused on a copper particle cluster of about 200 nm diameter, under SEM. After 5 minutes of electron beam focusing, the melting Cu started to climb into the MWCNT along the wall of the MWCNT. The electrical properties of MWCNT and MWCNT/Cu hybrid nanowire were measured through the model 4200 semiconductor characterization system (4200-SCS).

This method properly modifies the current pulsed MIG welding device by adding an airflow control branch of shielding gas for compensation, so that weld formation of the high-temperature, solid-liquid phase from the welding torch nozzle can be manually intervened and secondary gas protection of the weld surface can be implemented. This modified welding device with additional airflow is then used to conduct bead-on-plate pulsed MIG welding experiments using 18-8 type austenitic stainless steel as the base material. The study of microstructure and physical properties of the weld indicates that after introducing a certain amount of shielding gas for compensation, not only is weld formation significantly improved, but there is also timely track and protection of the weld surface. This largely inhibits the occurrence of welding defects during high-speed pulsed MIG single-wire welding and helps improve welding efficiency, and this study might demonstrate the necessity of further research and exploration.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132902071","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 system uses the OROCOS component-based framework for real-time functionality as well as its infrastructure for software component interaction. This together with the use some of the provided libraries and built-in development tools allowed for a rapid development approach. Direct addressing of a PCI-based I/O card peripheral hardware is described and proposed as a solution to the perennial challenge of hardware I/O in Linux partly occasioned by a lack of support for device drivers. The result is a fully functional control application that provides standard manipulator functionality as well as on-board analysis tools and capacity for sensor-based extended functionality. Moreover the resulting scheme is based on generic hardware that is available commercially off-the-shelf and can thus be replicated in its entirety.","PeriodicalId":403924,"journal":{"name":"2016 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127385222","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}
