This paper presents a method of control for minimizing damage and/or undesirable vibration of a single-link flexible arm due to collision using a collision detection function based on an innovation process of a Kalman filter constructed for a system without the collision input term. The controller is constructed for rotating the arm to the desired position in normal operations and interrupting its motion when the collision is detected.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130137611","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}

However, the formulations and results obtained for the rigid link manipulators cannot be directly applied to CDPM because of the unilateral property of cables. This paper focuses on the workspace analysis and optimal design of a specific type of CDPM, i.e. a completely restrained symmetric cable-driven planar parallel manipulator (CDPPM). The tension plays a key role in building up the workspace. In the analysis, performance criteria such as tension bound and stiffness condition are considered to construct the feasible workspace. Moreover, simplex search method is employed to obtain the optimal feasible workspace with respect to the locations of the connecting points and suspending points. Computation results have shown that the optimal workspace can be always obtained at configurations where either the base or the platform is degenerated to a line.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131330599","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}

They all have unique strengths and weaknesses in different environments, but in general, none seems sufficient on its own. In this paper, we present a new approach that adaptively combines multiple sampling strategies for PRM planning. Using this approach, we describe an adaptive hybrid sampling (AHS) strategy using two component samplers: the bridge test, a specialized sampler for narrow passages, and the uniform sampler. We tested the AHS strategy on robots with two to eight degrees of freedom. These preliminary tests show that the AHS strategy achieves consistently good performance, compared with fixed-weight hybrid sampling strategies.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114212350","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 many applications such as actuaphotonics or biomedical products, there are increasingly demands for machines that have positioning accuracy of several micrometers. In this paper, we present a prototype precision machine that has a positioning accuracy of 1 /spl mu/m and a peak speed above 1 m/s. The precision positioning machine uses a three phase permanent magnet linear motor as the actuator. As it is capable of producing linear motion directly, it eliminates the needs of mechanical transmission from the rotary to the linear motion. High closed loop performance has been achieved by using a state space based model predictive controller and a dynamic friction compensation system. The friction and the control system have been optimally identified and tuned using the genetic algorithm. Experimental results have verified the effectiveness of the developed approach.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128295451","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}

Therefore we can't need a priori information except both widths of the corridor and the robot, but we can easily design the visual feedback system for guidance and obstacle avoidance by using this method. The idea is based on perspective geometry such as perspective projection, epipolar geometry, vanishing point, and projective transformation.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134040120","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}

A novel decomposition of state is assumed first so that the constraints are linear in certain state variables. A simple and easily verified rank condition for the global /spl rho/-exponential stability of Caplygin systems is derived. A feature of our design is that all parameters can be explicitly determined from the constraint function or an important class of Caplygin systems in which one of the decomposed states is scalar, the rank condition can be explicitly represented as the conditions relating to the degree and non-zero property of the lowest degree polynomials of the Taylor series expansion of the constraint function at the origin. Moreover, an alternative form of Caplygin system in different coordinates is presented so that the proposed coordinate-dependent criterion can be applied. Examples such as extended power form, the rolling wheel and hopping robot systems are shown to belong to this class of Caplygin systems and thus their /spl rho/-exponential stability can be checked by the proposed test.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122245012","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}
