We consider that sequential displacements must be achieved by the robot and the table until finish the whole task. Thus, a method is proposed to find the successive placements that must be attained by the cooperative table in order to locate the workpiece in such a way that the kinematic performance of the robot be optimized during the task. The method is applied for a welding robot during the tracking of a 3D path. Simulation studies show the efficacy of the proposed method.","PeriodicalId":446027,"journal":{"name":"2018 XX Congreso Mexicano de Robótica (COMRob)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133470294","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}

These nonlinear fluid equations represent features like vehicular density, average vehicle velocities, occupation capacities and the interconnections between adjacent street segments and intersections. In order to enable more realistic traffic light actions, individual petri nets are defined for each the intersections, enabling or disabling the flow of vehicles. Therefore, the main contribution is the definition of a hybrid modular scheme of continuous differential equations with discrete-event systems. A numerical simulation of a simple intersection using Matlab shows the performance of the approach and its scalability to more complex traffic networks.","PeriodicalId":446027,"journal":{"name":"2018 XX Congreso Mexicano de Robótica (COMRob)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115548079","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 this aims, a constructive output-based robust control is designed based on: 1) sliding-mode observation theory, for state estimation; and 2) the attractive ellipsoid method, for control design. The closed-loop robust stability is proven through Lyapunov methods. The synthesis of the robust output-based control is expressed in terms of Linear Matrix Inequalities. Simulation results illustrate the feasibility of the proposed approach.","PeriodicalId":446027,"journal":{"name":"2018 XX Congreso Mexicano de Robótica (COMRob)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115433462","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}

Reinforcement Learning allows an autonomous agent to learn through experience how to solve a problem in an optimal way, with a minimal information of its environment, just a reward signal. This approach has lightened the way to an artificial intelligence capable of reaching superhuman performance in games such as Go and Backgammon, beating world champion players. Unfortunately this is far from a real world robot application due to many technological challenges. So in this paper we propose how to get a low-dimensional state representation for industrial robot manipulators, using visual information and Convolutional Autoencoders to speed up the information processing in the Reinforcement Learning training phase.","PeriodicalId":446027,"journal":{"name":"2018 XX Congreso Mexicano de Robótica (COMRob)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128986642","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}
