Physical modeling is the study of complex automated manufacturing and material handling systems through the use of small scale components controlled by mini and/or microcomputers. By modeling the mechanical operations of the proposed AGV material handling system, it was determined that control algorithms and AGV dispatch rules could be developed and evaluated. This paper presents a brief explanation of physical modeling as a simulation tool and addresses in detail the development of the control algorithm, dispatching rules, and a prototype physical model of a flexible machining system (FMS). It also includes quantitative results obtained in the operation and evaluation of the AGV dispatching rules.","PeriodicalId":438447,"journal":{"name":"Proceedings. 1987 IEEE International Conference on Robotics and Automation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128075283","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}

Conventional methods of planning the motion for a single moving object are based on the assumption of a static environment, and so they cannot be used here because each of the robots is in a dynamic environment consisting of other moving robots. Centralized approaches to the multiple moving objects problem were shown to be intractable. In order to find a practical solution for the problem, it is necessary to reduce the complexity of it by decomposing the problem and introducing various heuristic techniques. We are proposing here a decentralized approach which is based on the decomposition of the problem into two subproblems: the global path planning problem and the local path replanning problem. This approach is based on a framework of problem solving using a group of intelligent agents.","PeriodicalId":438447,"journal":{"name":"Proceedings. 1987 IEEE International Conference on Robotics and Automation","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121743017","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}

Recent works addressing this problem have attempted to match spatially local features from the image to features generated by models of the objects. However, many algorithms are less efficient than is possible. This is due primarily to insufficient attention being paid to the issues of reducing the data in features and feature matching. In this paper we discuss an algorithm that addresses both of these problems. Our algorithm uses the local shape of contour segments near critical points, represented in slope angle-arclength space (θ-s space), as the fundamental feature vectors. These fundamental feature vectors are further processed by projecting them onto a subspace of θ-s space that is obtained by applying the Karhunen-Loève expansion to all critical points in the model set to obtain the final feature vectors. This allows the data needed to store the features to be reduced, while retaining nearly all their recognitive information. The resultant set of feature vectors from the image are matched to the model set using multidimensional range queries to a database of model feature vectors. The database is implemented using an efficient data-structure called a k-d tree. The entire recognition procedure for one image has complexity O(IlogI + IlogN), where I is the number of features in the image, and N is the number of model features. Experimental results showing our algorithm's performance on a number of test images are presented.","PeriodicalId":438447,"journal":{"name":"Proceedings. 1987 IEEE International Conference on Robotics and Automation","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131404922","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 presents an efficient computation scheme to calculate the actual positions and orientations of the end-effectors of manipulators consisting of straight thin-walled hollow links and revolute joints, of which most contemporary robots are made up. Local principal coordinate frames are defined for deflection analysis. Displacements are computed using formulae derived from classical beam theory. For compliance analysis, the robot joints are considered as torsional springs, where the first order approximation is applied. A hypothetical two-link robot is used to demonstrate the techniques. Results are verified by analytical solutions, and the differences are less than 1% of the deflections.","PeriodicalId":438447,"journal":{"name":"Proceedings. 1987 IEEE International Conference on Robotics and Automation","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131504818","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}
