These main elements are the advisory, computer aided expert system, the safety mode controller and the human awareness interface. The introduced approach allows to ensure the required level of safety for the collaborative tasks performance in manufacturing setup within or beyond the robotized workcell. The generated protocols of the expert system, safety criteria (danger index) and functional modes are the determining elements of the safety framework. The expert system, which inference engine is built on the fuzzy theory application, provides designer with an explicit workcell ergonomic and human factor analysis, task related hazards and risk category evaluation. Safety mode controller functional algorithm is based on the safety modes monitoring parameters definition and their continuous control. It is represented as a separated unit that monitors interconnected elements in compliance with the safety criteria and predefined transition rules. The proposed human warning system, mounted on the individual wrist and interconnected with the overall safety system, suppose to alert an operator about the system current state by imparting vibrotactile and visual cueing in compliance with predefined rules.","PeriodicalId":104308,"journal":{"name":"19th International Workshop on Robotics in Alpe-Adria-Danube Region (RAAD 2010)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130301657","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 robot learning based on imitation of human activity we often use statistical methods that generalize observed (learned) movements. The acquired data is used to generate useful robots responses in situations for which the robot has not been specifically instructed how to respond. The paper describes the robot learning with Gaussian process regression that creates the model and estimates the parameters for generalization of the acquired motor knowledge, which is accumulated as a database of example movements. New actions are synthesized by applying Gaussian process regression, where the goal and other characteristics of an action are utilized as queries to create an optimal control policy with respect to the previously acquired knowledge. The paper demonstrates that the proposed methodology can be integrated with an active vision system of a humanoid robot. 3D vision data is used to provide query points for statistical generalization.","PeriodicalId":104308,"journal":{"name":"19th International Workshop on Robotics in Alpe-Adria-Danube Region (RAAD 2010)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130911288","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}

Usually several types of sensors are used to control it. This article focuses on the emergency situation, when only few sensors are available. These sensors are mainly the inertial ones. Certainly, these sensors are not enough for normal maneuvering, but the controlled system should be able for horizontal stabilization and safe landing. Two types of control are presented. The first is a casual LQ state feedback. The disadvantage of this type of control in real environment is shown. The second control algorithm is an H∞ control method. The control design starts from a very simple linear model. The parameter measurement of the linear system is shown. The goal of this article is to handle the uncertainty in the behavior of the real system.","PeriodicalId":104308,"journal":{"name":"19th International Workshop on Robotics in Alpe-Adria-Danube Region (RAAD 2010)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134080761","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 paper describes an optimization approach that enables the generation of a new motion trajectory, which accomplishes the task in a given situation, based on a library of example movements. New movements are generated by applying statistical methods, where the current state of the world is utilized as query into the library. Dynamic movement primitives are employed as the underlying motor representation. The main contribution of this paper is the optimization of dynamic movement primitives with respect to the kernel function positions and over the entire set of demonstrated movements. We applied the algorithm to a robotic throwing task, where the location of the target is determined by a stereo vision system, which can detect infrared markers. The vision system uses two Nintendo WIIMOTEs for cameras.","PeriodicalId":104308,"journal":{"name":"19th International Workshop on Robotics in Alpe-Adria-Danube Region (RAAD 2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115230101","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}

Other objects such as analysis results, manufacturing methods, and equipment control programs are mapped to part and assembly definitions. This style of engineering has been realized in model and simulation based product development. Product data management systems as extensions to product modeling and simulation systems were forced to apply engineering process definition for organization of group work. Some drawback of the above modeling motivated the authors to define an additional content based extension to current product modeling and simulation for entities of human intent, engineering objectives and decisions. In this paper, the authors analyze characteristics the above process elements and features and define typical engineering processes. Problems with the currently applied product model and an earlier proposed solution by the application of information content based product model extension are introduced. Following this, four typical information content based engineering processes are explained. Finally, robot system is characterized together with its environmental model as a well suitable product for the proposed modeling.","PeriodicalId":104308,"journal":{"name":"19th International Workshop on Robotics in Alpe-Adria-Danube Region (RAAD 2010)","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131666283","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}
