병렬구조 모션 시뮬레이터 이클립스-Ⅱ를 위한 가상현실 시험경로 개발
인우성(Woosung In),김종원(Jongwon Kim) 한국정밀공학회 2004 한국정밀공학회 학술발표대회 논문집 Vol.2004 No.10월
This paper describes the development of the test path for Eclipse-Ⅱ, a parallel mechanism motion simulator. Eclipse-Ⅱ which can be used as a base for general motion simulators, enables unlimited continuous 360-degree spinning in any rotational axes plus finite X, Y, and Z translation motions. The advantage of enabling continuous 360-degree spinning allows various motions for virtual reality. In this paper, the development of the test path to verify the robustness of the Eclipse-Ⅱ motion simulator is described. The test motions, which satisfy the requirements of test path, are suggested and washout filter enables these motions reproduced in the limited workspace. The trial run is conducted to verify the robustness of the Eclipse-Ⅱ motion simulator. Additionally the standard data format of virtual reality for Eclipse-Ⅱ One Man Ride is suggested.
A new planar 3-DOF parallel mechanism with continuous 360-degree rotational capability
서태원,인우성,김종원 대한기계학회 2009 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.23 No.11
This paper presents a novel three degrees of freedom (3-DOF) planar parallel mechanism with a 360-degree rotational capability, which can be used as a positioning device. A high rotational capability is necessary to reduce process time and to apply the mechanism to various fields such as micro-machining and printed circuit board (PCB) depaneling. The proposed mechanism has the advantage of a continuous rotational capability over existing planar parallel mechanisms with limited rotation. The position and velocity kinematics are derived, and the singularities are analyzed based on the Jacobian matrices. The workspace can be determined not to have a singularity inside, and the kinematic variables for enlarging the singularity-free workspace are determined. The application example on the PCB depaneling process is proposed for future work.

This paper presents a redundantly actuated six degrees-of-freedom parallel kinematic mechanism with a partially decoupled architecture in its rotational motion. This mechanism is developed to eliminate kinematic complexity of original Eclipse-II known as a redundant parallel mechanism. Since the original Eclipse-II mechanism use kinematic redundancy of parallel mechanism to achieve an advantage in enlarging the workspace of the system, it needs a motion planning algorithm to choose the specific control inputs to determine the desired motion trajectory. This motion planning algorithm causes difficulty in achieving real-time control performance due to its structural complexity. However the redundant parallel mechanism presented in this paper is a redundant parallel mechanism with partially decoupled architecture in its rotational motion. Therefore modified Eclipse-II redundant parallel mechanism can realize effective real-time control performances and continuous 360-degree rotational motion in any direction of the moving platform with six degrees of freedom.

High performance turbo compressor, Turbo Master, was successfully developed by applying combined technology and experience based on aero gas turbine engines. The Turbo Master, developed using our own technology, was designed for high performance and reliability. And the Turbo Master will supply absolutely oil-free compressed air to your facilities. In special, a next-generation micro compressor was lately developed, using air foil bearing and high speed motor known as the latest high technology.
