The measured variables are the control laws of the motors and the angles between the robot principal axis and a lot of fixed beacons, given by a rotative onboard camera. The specific problems are of several types: the motion of the robot is described by a continuous-time nonlinear equation. The measures are uncadenced and nonlinear (angles). The state of the robot is not observable by a single measure. So a specific continuous/discrete-time extended Kalman filter with measurement reconstruction is developed.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115862839","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 the past, path planning has often been referred to as a 'high level' task and has been completely separated from the so called 'lower level' control of a real mobile vehicle. The authors consider here the total energy of a mobile vehicle when influenced under a good seeking navigation strategy. This energy function is used to produce a control law directly to drive a mobile vehicle. The authors also incorporate directly an estimate of an artificial repulsive potential field into the low level controller.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129962028","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 paper shows how to plan the shortest collision-free path in 3D, when a robot is navigated to pick up some tools or to repair some parts from various locations. A path coordinator is proposed having the capabilities of an obstacle avoidance strategy and a traveling salesman problem (TSP) strategy. The obstacle avoidance strategy is to plan the shortest collision-free path between each pair of n locations in 2D or in 3D. The TSP strategy is to compute a minimal system cost of a tour that is defined as a closed path navigating each location exactly once. The TSP strategy can be implemented by the neural network. The obstacle avoidance strategy can be implemented by the optimal edges by the modified genetic algorithm and computes the optimal nodes along the optimal edges by the recursive compensation algorithm.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130243327","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 structure of the model corresponds to the structure of the system only up to a certain limit. Error correcting is formulated as an optimization problem where the norm of the difference between the measured and the predicted system behavior is minimized. The solution is searched iteratively by doing the same task or experiment repeatedly and utilizing previously observed results. It is argued that the optimization approach may be useful in understanding the problems encountered in memory-based modeling, particularly in robot control. An iterative algorithm is given to correct the robot positioning errors. It is shown to converge to the right solution by making some general assumptions of the existing robot controller. An example is given with the PUMA robot where the precision of the arm movement is increased by repeatedly doing the movement task.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114792615","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}

When the pushing force vector applied to an object passes through the center of friction which is the centroid of the friction distribution, the motion of the object is a pure translation. The authors describe a method for estimating the friction distribution of an object and the position of the center of friction by pushing the object several times using a manipulator mounted on a mobile robot, which also has a visual sensor. Simulation and experimental results show the effectiveness of the approach.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114378723","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}
