In this method, the coupling characteristics of manipulator dynamics are used, and no additional mechanisms are required. In the paper, the effectiveness of the method is verified by experiments using a prototype manipulator. The prototype is a two degree of freedom horizontally articulated manipulator. The first axis is an active joint and the second axis is a passive joint. While the brake of the passive joint is released, the passive joint is indirectly controlled by the motion of the active joint, through the use of dynamic coupling. While the brake is engaged, the active joint is controlled. By combining these two control modes, total position of the manipulator is controlled. The experiments show that the precise positioning of the passive joint is feasible by use of the proposed method.<<ETX>>","PeriodicalId":409624,"journal":{"name":"EEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114655502","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}

Three types of models are developed in the paper. The first one is a single-link pendulum robot with an additional mass able to slide up and down on a straight path along the link. It can perform a giant swing. This model is developed to make a study about the mechanism of a giant swing and increasing swing amplitude. The second is the three-link model consisting of arms, trunk and legs. It can perform a skip, a giant swing and other stunts which require bent knees. The third is four-link model with bent knees. In this model the coordinates of the position of the body in sagittal plane are added so that it can perform aerial stunts and landing. For the three models computer simulations show that the control strategy to realize the high bar stunts depends mainly on the control of the position of the center of the gravity of the whole body. Except for the four-link model, physical models are constructed. The three-link gymnast robot can perform sequential stunts by the same control strategy to that of the computer simulations.<<ETX>>","PeriodicalId":409624,"journal":{"name":"EEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125255039","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 these domains the availability of good sensory information becomes vital to the success of the task, off-line simulation must therefore simulate not only the robot movements but also the sensory information on which these movements are based. One of the most powerful sensory mechanisms available to a robot is vision but little has been done so far to incorporate visual sensory simulation into robot simulation. This paper describes a method for generating accurate visual sensory information during the simulation of a robot task and shows how this can enable the complete simulation of the task, particularly the connection between sensing and action.<<ETX>>","PeriodicalId":409624,"journal":{"name":"EEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130338731","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 is concerned with the resolution of this kinematic redundancy, and in particular with the local optimization of the position and configuration of the system during task commutations when changes occur in both task requirements and task constraints. Optimization criteria for obstacle avoidance, manipulability, least torque norm and maximum actuator torque are first discussed. Emphasis is then placed on optimization methods for problems involving multi-requirements and multicriteria optimization. Sample results of the methods for a system including a three-link manipulator mounted on a mobile platform are presented and discussed.<<ETX>>","PeriodicalId":409624,"journal":{"name":"EEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116313409","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 memory-based control schemes, all values concerning robot motion are stored in memory of digital computers instead of modeling the robot motion and the environment around the robot. The authors propose a memory-based control scheme which is suitable for locomotion of robots in unknown environment. At the first step of the proposed control scheme, a robot recognizes the unknown environment through test motions which mean actual movement of the robot. As a result, the robot has knowledge of the motion environment as a kind of map in the memory of digital computers. At the second step, by using path planning techniques in the environment maps obtained by the test motions, the robot forms a motion pattern which can realize effective locomotion. The effectiveness of the proposed memory-based control scheme is demonstrated through two experimental results in which robots move in the water and on the ground.<<ETX>>","PeriodicalId":409624,"journal":{"name":"EEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123992704","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}
