The T-junctions that match the conditions of angles checking and coordinate comparing will be detected as initial and end points of weld seam. The proposed method mainly insists of the 4 steps namely 1) smoothing the image and extracting edges of the image by using Canny operator 2)linking broken edges 3)detecting T-junctions and 4)analysing the initial and end points of weld seams.

It's of great challenge and interest to design and fabricates a micro robot that can walk on a water surface like water strider to carry out aquatic tasks such as water quality monitoring, aquatic exploration, water search and rescue. In this study, we designed a new type of biologically inspired water-jumping robot on the basis of the locomotion mechanism of water strider. The lifting force of the supporting legs, the driven force obtained by the actuating legs and the resistant force exerted on the robot are analyzed by simplified models. A dynamic analysis and simulation by ADAMS are performed on the jumping movement of the robot. By optimizing the robot structure, and adjusting the driven mode and the center of gravity location, the robot finally possesses a good jumping performance on water surface in a typical simulation. This study not only offers a better understanding of the water-jumping capability of water strider, but may prove helpful in the research of water strider robots.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128341992","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 obtain a long focusing distance, a new flexure positioning mechanism is devised based on multi-stage leaf springs. The proposed device allows a precise focusing without friction and backlash effects. A voice coil motor is employed to drive the positioning mechanism. The stiffness model and resonant-frequency model are developed analytically. These models are employed for an architectural optimization of the mechanism parameters to maximize the resonant frequency under the driving stroke and force constraints. The performance of the designed flexure mechanism is validated through finite-element analysis (FEA) simulation investigations. Results show that the positioning mechanism enables a long focusing range over 10 mm with a high resonant frequency over 450 Hz, which allows an auto-focusing operation with rapid response. Moreover, the performance of the auto-focusing device is validated through experimental studies on a fabricated prototype.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115129305","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}

In order to improve the parameters identification accuracy of friction model, and overcome the error effects of the low speed velocity measurement, the full-order speed observer is designed as feedback speed information. Experiments platform has been built and some dragging experiments on the EER have been done.

In the past such systems have typically been developed as “one off” experimental systems in part due to a lack of common software systems for both robot software development and virtual environment infrastructure. More recently, common frameworks have begun to emerge for both robot control (e.g., ROS) and virtual environment display and interaction (e.g., Unity). Here we consider the task of developing systems that integrate these two environments. A yaml-based communications protocol over web sockets is used to glue the two software environments together. This allows each system to be controlled using standard software toolkits independently while providing a flexible interface between these two infrastructures.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123256461","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 study focuses on the criterion of short training, or possibly zero training. Due to the non-stationarity inhered in surface electromyography (sEMG) signals, the system may need to be re-trained day by day in the extended usage of myoelectric protheses. However, as the subjects perform the same motion types in different days, we hypothesize there still exists some invariant characteristics in the sEMG signals. Therefore, give a set of training data from several days, it is possible to find an invariant component in them. To this end, an invariant feature space analysis (IFSA) framework based on kernel feature extraction is proposed in this paper. A desired transformation, which minimizes the dissimilarity between sEMG feature distributions of different days and maximizes the dependence between the training data and their corresponding labels, is found. The results show that the generalization ability of the classifier trained on previous days to the unseen testing days can be improved by using IFSA. More specifically, IFSA significantly outperforms Baseline (original input feature) with average classification rate of 1.11% to 1.69% (p <; 0.0001) in task including 9 motion classes or 13 motion classes. This implies that the promising approach can help for achieving the zero-training of MPR.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116193851","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}
