This system helps the operator by taking a task and reduces his/her workload. Unfortunately, the transparency is deteriorated due to the operational force caused by a dynamic motion of the target. This effect is caused by the discreteness and a delay in external sensors essential for MCBC. However, the relationships between the transparency and those sensing constraints were not clarified yet. Therefore in this research, the frequency characteristics of the transparency for the MCBC are analyzed in the following three basis: type of holds, sampling period, and stiffness of the target. The analytical results suggested following three behaviors in the transparency of the MCBC. · A first order hold showed better performance compared with a zero order hold, but it has a peak gain near the Nyquist frequency · Shorter sampling period improves the performance · Contacting hard target deteriorate the performance The validity of analysis was verified by the experimental results.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"19 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90641576","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}

Classic control algorithms such as P, PI, Pd and PID are applied to the real model with various parameters and the obtained results are compared.

By using DOB, acceleration control is achieved. As a result, DOB is contributed to robust position and force control. In other front, DOB is utilized as the reaction force observer (RFOB) for estimation of the external force. As a result, DOB is a key technology for motion control. Therefore, it is necessary to improve the performance of DOB to realize high advanced motion control system. The performance of DOB depends on motion control frequency, current control frequency of motor driver and the resolution of encoder. This paper focuses on motion control frequency and current control frequency. The purpose of this paper is realization of high-performance DOB based on fast motion control frequency and fast current control frequency.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"8 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87944370","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 observer is designed from state space expressions of a controlled plant with the LuGre model that is locally-linearized every sampling period. Thus, observer gains derived from the linearized model become time variant ones as a function of velocity. Parameters of the LuGre model were experimentally identified for a linear stage driven by a ball screw with an AC motor, i.e., a controlled plant. To show the validity of the proposed method, experiments using the controlled plant were conducted to evaluate tracking errors for positioning control with and without the proposed disturbance observer. From the experimental results, it has been confirmed that the proposed disturbance observer can eliminate influence of the friction and is effective to improve positioning accuracy.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"491 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86786727","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}

Bio-inspired propulsion methods emerge as realistic substitutes for hydrodynamic thrust generation in micro realm. Accurate modeling, power supply, and propulsion-means directly affect microrobot motility and maneuverability. In this work, motility of bacteria-like untethered helical microrobots in channels is modeled with the resistive force theory coupled with motor dynamics. Results are validated with private experiments conducted on cm-scale prototypes fully submerged in Si-oil filled glass channel. Li-Po battery is utilized as the onboard power supply. Helical tail rotation is triggered by an IR remote control. It is observed that time-averaged velocities calculated by the model agree well with experimental results. Finally, time-dependent performance of a hypothetical model-based position control scheme is simulated with upstream flow as disturbance.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"22 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78480276","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 approach is based on the Zero Moment Point (ZMP) stability criterion and the Linear Inverted Pendulum Model (LIPM). ZMP reference trajectories for pace is proposed, from which reference trajectories for the Robot Center of Mass (CoM) references are obtained by applying preview control. The position of leg joints are computed using inverse kinematics according to CoM reference trajectory. Proposed reference trajectory generation synthesis is tested through full-dynamics 3D simulation. A 16-degrees-of-freedom (DOF) quadruped robot model is used in the simulations.

However, the cooperative motion between humans and robots using mobile robots has not yet been researched very much. To address this problem, this paper presents the application of motion control method for safe navigation based on human's behavior using two-wheel mobile manipulator, because it has better mobility and it can pinwheel. In this study, human's behavior is divided into phases and virtual impedance is changed depending on if cooperative walking situation is dangerous or not. To verify the validity of proposed method, experiments of human-robot cooperative motion were carried out.

Energy efficiency and locomotion velocity of our robots, for example, are orders of magnitude lower than those of animals, and in order to fill the gap, it requires a radically new approach in the design and control processes. From this perspective, we have been exploring a novel approach to design and control of legged robots which makes use of free vibration of elastic curved beams. We found that this approach not only simplifies the design and manufacturing processes of locomotion robots, but also substantially improves their energy efficiency, which is comparable to those of animals. In this paper, we explain the novelty and principles of this approach through the four representative case studies that we have been exploring, and discuss challenges and perspectives toward the future.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82131359","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}
