スノーボード人気を先取りして設立した会社が清算に追い込まれた。数百ものブランド乱立のあおりで,原価割れ販売を余儀なくされた。「儲からない構造」に気づき,早めに撤退の決断を下した。スノーボード輸入販売会社のエヌシーエスは,今年6月をメドに,会社を清算することに決めました。今は在庫処理が目的で販売しているだけです。

In this paper, we propose a new design concept of manipulator which is called “Torque-Unit Manipulator (TUM) ”. The Torque-Unit Manipulator has an open-loop kinematic chain as the typical traditional manipulators do, however each joint of which has one degree of freedom free joint. An actuator called “torque unit” is mounted on an arbitrary place of the link. The merit of the TUM would be an easy maintenance. In this paper, the dynamic model and the position-controllability of the N degree-of-freedom general TUM are shown in detail. A control system is designed for the TUM and its effectiveness is shown by a simple simulation.

Optimal reference trajectories for n-link robot manipulators are planned. They are generated from the performance indices which are the integral of the square of acceleration, jerk, and so on of the trajectory with respect to the control time. The optimal reference trajectories are compared through an experiment in high-speed motion control of a 2-link robot manipulator, and a good control performance is obtained in the case of higher continuity of the trajectory.

This paper presents a robust control law which achieves model following with prescribed accuracy for a class of nonlinear systems which contain bounded unknown disturbances and uncertain nonlinear terms. Our method consists of nonlinear compensation and linear compensation. The former ensures robustness for the plant, the latter achieves both desired model following response and desired initial error convergence. The distinguish feature of our method is that admissible control error bound, smoothness of input, reference model (or desired command response), and initial error response can be specified independently, and that the controller is designed based on the information of the “bounds” of uncertainty terms.
