The collision avoidance motion is first generated in off-line routine and its data are stored as as a sequence of desired joint angles. Next, virtual impedance model-following control is employed as force feedback control. Redundancy is used for minimization of the variance from the desired joint angle during compliant motion. In particular, the computation time for the inverse kinematics at each sampling time was reduced by using approximate values of Jacobian matrix. The stability of the control system is analyzed and the effectiveness of the proposed method is discussed.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"85 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":"124559573","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 elements are integrated into a hierarchical system architecture wherein control bandwidth decreases about an order of magnitude from level to level, goals expand in scope and planning horizons expand in space and time about an order-of-magnitude from level to level, and perception of spatial and temporal patterns, models of the world, and memories of events decrease in resolution and expand in spatial and temporal range by about an order-of-magnitude from level to level. At each level, functional modules perform behavior generation, world modeling, sensory processing, and value judgment. Behavior generation modules perform task planning and execution. The world model is the intelligent system's best estimate of the external world. Value judgments provide an evaluation of hypothesized plans, and perceived objects, events, and situations. Sensory processing modules transform sensory maps into world model maps and extract entity attributes and states.

Each controller independently determines the way how to move each link. The necessary information for the controller is the target position, the position of the end-effector and the position of the link. Each controller has the same control law and common information on the target position and the end-effector position. Thus, the authors call it 'distributed autonomous'. The proposed control architecture has two main advantages: (1) robustness, even if several number of links are out of order, the total system will still work normally; and (2) obstacle avoidance, if the obstacle satisfies some conditions, the robotic manipulator will avoid it automatically.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"10 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":"121345847","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 authors define the problem and derived the equations of motion for a robot and a pushed box. The authors take the rule-based control scheme as a fundamental tool for control. The authors have analyzed the equations of motion and found that the situation is similar to the problem of an inverted pendulum popular in the usual automatic control theory. In normal situations the stability is more urgent than to follow a trajectory. By this observation the authors have introduced a hierarchical structure in rules. That is, the rules to maintain the angle between the robot and its box small is applied first. Other rules are considered only when the angle is sufficiently small. The authors adopt crisp rules, which means that they divide a given variable into intervals, and in each interval they have different set of rules. The total number of rules used in the experiments is 120.<<ETX>>","PeriodicalId":388962,"journal":{"name":"Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91","volume":"2 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":"127941176","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}
