103. Mechanism of Micro Manipulation using Oscillation

Author

Watanabe, Tetsuyou, Jiang, Zhongwei, Watanabe, Tetsuyou, and Jiang, Zhongwei

Abstract

In this paper, we analyze the mechanism of the phenomenon between an endeffector, a micro object and a substrate during a micro manipulation. In a micro range, the attracting forces such as the van der Waals, capillary, and electrostatic forces dominate and course adhesion between the object and the endeffector. The adhesion makes the manipulation of an object difficult. Recently, we developed a method to reduce the attracting/adhesion effect. When bringing an oscillating endeffector close to a micro object on a substrate, the attracting force between the object and the endeffector is reduced, attracting the object to the substrate. Then, it becomes easy to remove the endeffector from the object. Using this method, a micro object can be easily manipulated. However, the mechanism of the phenomenon is still unclear. In this paper, we develop the theoretical model of the system to analyze the phenomenon, and simulate the dynamical motion of the system. Comparing the experimental results, we show the validity of our approach. Using simulation and experiment, we show that the oscillation of the endeffector can reduce the adhesion effect between the endeffector and the object, attracting the object to the substrate. © 2006 IEEE.

104. Micromanipulation using squeeze effect

Author

Watanabe, Tetsuyou, Fujino, Nobuhiro, Jiang, Zhongwei, Watanabe, Tetsuyou, Fujino, Nobuhiro, and Jiang, Zhongwei

Abstract

In this paper, we proposed a novel strategy for pick and place operation in a micro range, by using a squeeze effect In a micro range, the attracting forces such as the van der Waals, capillary, and electrostatic forces are dominate due to the scaling effect. The attracting forces make a release of an object difficult. In this paper, by vibrating the finger, we generate the gas film (the squeeze effect) between the object and the finger and relax the attracting forces. Some experimental results are shown to verify our approach.

105. Object Manipulation under Hybrid Active/Passive Closure

Author

Watanabe, Tetsuyou, Harada, Kensuke, Jiang, Zhongwei, Yoshikawa, Tsuneo, Watanabe, Tetsuyou, Harada, Kensuke, Jiang, Zhongwei, and Yoshikawa, Tsuneo

Abstract

In this paper, we discuss the manipulation of an object under hybrid active/passive closure. We show the orthogonality between the directions of active and passive force closures for general grasping systems. Based on the orthogonality, we decompose the dynamics of grasping system into the "active part" and the "passive part". By using the decomposition, we show that the grasped object can be manipulated only by considering the dynamics of the active part. We also consider how to determine the desired internal forces in order to satisfy frictional constraints during the manipulation. In order to verify the validity of our approach, some simulation results are shown.

106. Towards Whole Arm Manipulation by Contact State Transition

Author

Watanabe, Tetsuyou, Harada, Kensuke, Yoshikawa, Tsuneo, Jiang, Zhongwei, Watanabe, Tetsuyou, Harada, Kensuke, Yoshikawa, Tsuneo, and Jiang, Zhongwei

Abstract

This paper discusses the whole arm manipulation allowing the contact state transition. For manipulation of an object under fully constrained, the contact state transition becomes necessary. In order to realize the object manipulation, we first derive the feasible direction of the object manipulation by analyzing the active/passive closure properties for every combination of contact states. Second, we derive the set of joint torque to move the object in the feasible direction. These analyses also provide the joint torque to realize the manipulation at the planned contact states. Effectiveness of the proposed method is confirmed by some simulation results. © 2006 IEEE.

Abstract

金沢大学理工研究域機械工学系, This paper addresses to develop a novel strategy to relax the adhesion forces for picking and placing operation in a micro range. In a micro range, the attracting forces such as the van der Waals, capillary, and electrostatic forces become dominating due to a scaling effect. The attractive forces cause the adhesion between the object and the endeffector. Therefore, it is hard to manipulate an object in a micro range. This paper shows that when an oscillating endeffector approaches to an object, the adhesion between the object and the oscillating endeffector can be reduced. Also, based on the experimental analysis, we clarify the relation between the oscillation and the pushing amount of the endeffector on the object, where the adhesion force can be released effectively. Using this relaxation method and the relation, we develop a strategy for picking and placing operation in a micro range. This strategy provides an accurate manipulation. Some experimental results show the effectiveness of this approach.

Abstract

Engineering has been playing an important role in serving and advancing healthcare. The term "Healthcare Engineering" has been used by professional societies, universities, scientific authors, and the healthcare industry for decades. However, the definition of "Healthcare Engineering" remains ambiguous. The purpose of this position paper is to present a definition of Healthcare Engineering as an academic discipline, an area of research, a field of specialty, and a profession. Healthcare Engineering is defined in terms of what it is, who performs it, where it is performed, and how it is performed, including its purpose, scope, topics, synergy, education/training, contributions, and prospects.

Abstract

By using the method of documentation,the adaptability of the theory of good governance in the governance mechanism of campus football and the current situation of the governance mechanism of campus football in China are analyzed. It is concluded that there are some problems affecting the governance of campus football, such as the dislocation of policy implementation objectives, the imperfection of management system,the insufficient funds for teachers and facilities, and the imperfection of supervision and evaluation system. Because the theory of good governance is universal and meets the needs of reform and innovation in China,this paper,based on the theory of good governance, makes an analysis of the governance mechanism of campus football in China from four aspects: the identification mechanism of good governance, the formulation and implementation mechanism of good governance policy, the guarantee mechanism of good governance, and the supervision and evaluation mechanism of good governance, in order to provide a new direction for the governance mechanism of campus football in China and promote the efficient operation of campus football.
