These forces decrease significantly when the micro-objects are submerged in a liquid medium. So a microassembly task is easier to perform in a submerged medium than in air. Consequently, the study of the micro-objects assembly automation in liquid mediums is a promising topic. This article introduces a review of the major differences between dry and submerged micromanipulation. The influences of the medium on electrostatic forces, pull-off force and hydrodynamic forces are presented. Adhesion perturbations are significally reduced in liquid and hydrodynamic forces are advantageous to limit the maximal micro-objects velocity. Some comparative experimental micromanipulations are described and prove the interest of the liquid medium.","PeriodicalId":162553,"journal":{"name":"2005 International Symposium on Computational Intelligence in Robotics and Automation","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123608950","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}

Reinforcement learning is a well formulated method for autonomous robots to obtain a new behavioral concept by themselves. However, these behavioral concepts cannot be applied to other environments that are different from the place where the robots have learned the concepts. On the contrary, we, human beings, can apply our behavioral concepts to some different environments, objects, and/or situations. We think this ability owes to some memory structure like schema system that was originally proposed by J. Piaget. We previously proposed a modular-learning method called Dual-Schemata model. In this paper, we add a reinforcement learning mechanism to this model. By being provided with this structure, autonomous robots become able to obtain new generalized behavioral concepts by themselves. We also show this kind of structure enables autonomous robots to behave appropriately even in a novel socially interactive environment.","PeriodicalId":162553,"journal":{"name":"2005 International Symposium on Computational Intelligence in Robotics and Automation","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129485824","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 proposed AWNN control system, a WNN with accurate approximation capability is employed to approximate the unknown dynamics of the PMLSM, and a robust term is proposed to confront the inevitable approximation errors due to finite number of wavelet basis functions and disturbances including the friction force. The adaptive learning algorithm that can learn the parameters of weight, dilation and translation of the WNN on line is derived using Lyapunov stability theorem. Moreover, to relax the requirement for the bound of uncertainty in robust term, which comprises a minimum approximation error, optimal parameter vectors, higher-order terms in Taylor series and friction force, an adaptive bound estimation law is investigated where a simple adaptive algorithm is utilized to estimate the bound of uncertainty. Furthermore, the experimental results due to periodic reference trajectories show that the dynamic behaviors of the proposed control systems are robust with regard to uncertainties.","PeriodicalId":162553,"journal":{"name":"2005 International Symposium on Computational Intelligence in Robotics and Automation","volume":"30 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115862938","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 motion capturing method has been developed mainly for analysis of human movement, but very rarely used to teach a robot human behavior in an on-line manner. In the traditional teaching method, robotic motion is captured and converted into the virtual world, and then analyzed by human interaction with a graphical user interface. However such a supervised learning framework is often unrealistic since many real-life applications may involve huge datasets in which exhaustive sample-labeling requires expensive human resources. Thus in our learning phase, we initially apply the supervised learning to just small instances using a traditional principal component analysis (PCA) in the off-line phase, and then we apply the incremental PCA learning technique in the on-line phase. Our on-line PCA method maintains the reconstruction accuracy, and can add numerous new training instances while keeping reasonable dimensions of the eigenspace. In comparison to other incremental on-line learning approaches, which use each static image, our proposed method is new since we consider image sequences as a single unit of sensory data. The extensions of these methodologies include the robotic imitation of human behavior at the semantic level. The experimental results using a humanoid robot, demonstrate the feasibility and merits of this new approach for robotic teaching.","PeriodicalId":162553,"journal":{"name":"2005 International Symposium on Computational Intelligence in Robotics and Automation","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122551382","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}
