An artificial neural network (ANN) is employed to generate the desired joint angle, and then, particle swarm optimization (PSO) is used as the learning algorithm. The sum of the motor torques is adopted as the objective function in the PSO algorithm. By operating the manipulator along the trajectory obtained using the proposed method, residual vibrations can also be suppressed. The applicability and effectiveness of the proposed trajectory planning method are confirmed by performing numerical simulation and verified by experimental results.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115462928","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 traditional approaches, a task planning system based on STRIPS (Stanford Research Institute Problem Solver) representation is widely used. Also the temporal planning is one of the issues in task planning area, since it still suffers some problems for single robots, and also it is not easy to apply to multi-robot environment yet. For our objective, we propose a new representation, named variable representation, based on STRIPS representation for specifying states and actions. Then we apply the A* algorithm for iterative search and extend for multi-robot task planning system. In order to guarantee safety, the multi-robot task planning system needs to check robots' collisions and should avoid robots' collisions. We propose collision check and avoidance algorithm, and integrate to the multi-robot task planning system.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"444 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116561044","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 gap contributes to decrease passengers' safety. Especially, it endangers children's safety. Nowadays plug-in type doors are installed in the newly designed urban transit system. It is worldwide trend to reduce the noise coming from the outer side of vehicle. But this plug-in door basically needs wider gap between door and platform and it maybe raise a serious accident. Sliding step is suggested to minimize gap and to overcome this safety problem at platform.

Among many approaches the game theory has presented feasible solutions. In this paper, a noncooperative approach which gives rise to a noncooperative game is studied, we propose to model signalized intersections as finite controlled Markov chains and a solution to optimize the congestion into an avenue. Each intersection is seen as noncooperative game where each player try to minimize its queue, so ϵ-Nash's equilibrium and Stackelberbg equilibrium are the solutions. This paper is focused on the traffic light control problem for urban traffic, using Game Theory and Extraproximal Method for its realization. The examples show the effectiveness of the suggested approach.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114395922","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}

Thus, the recent society of Japan is called as “Elderly Society”. In the society, many elderly people work or enjoy walking to keep health. However, some problems with respect to stumble over of elderly people are occurred. That is to say, in recent years, accidents of bone fracture with elderly people increase because of tendency to fall by a little step in a house. As one of this cause, it is considered that a center of gravity position with foot parts is changed. Therefore, in order to solve this problem, we propose a new type of high performance insole by making use of sponge-core-soft rubber actuator (SCSRA). In this study, we indicate the structure of the insole. Further, the basic characteristics of the insole are clarified through some experimental results.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122048388","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}

One common method of determining TDOA is to compute the cross correlation function. The Generalized Cross Correlation (GCC) method, which calculates the correlation function by using inverse Fourier transformation of the cross power spectral density function multiplied by the proper weighting function, was proposed by Knapp and Cater in 1976. This method analyzed the weighting functions to estimate the optimal TDOA for a single source. In this paper, we derived the cross correlation function by GCC method with PHAT weighting function for multiple sources and ascertained the relationship between the correlation value and source characteristics. Moreover, we compared the derived GCC function for two sources case with the real GCC function calculated by the actual signals and verified their similarity.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122231374","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}

We introduce a novel method of walking pattern generation by applying the proposed technique to the biped humanoid robot. Our aim is to simplify the walking control by utilizing a real time tactile feedback instead of the complex ZMP calculations. We employ the minimum number of sensing elements with a specialized layout to the soles of robotic feet to enable the robot to walk on different uneven grounds. The effectiveness of the proposed method was confirmed by walking experiments with a 17 degree-of-freedoms, DOFs humanoid robot platform. The experiments show that the robot can perform balanced walking on the upward and downward slopes. In these experiments, information about ground floor or robot orientation is not required in advance.","PeriodicalId":158687,"journal":{"name":"ICCAS 2010","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128388543","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}
