  • 이 논문은 크로스아암이 부상제어기에 미치는 영향을 분석한다. 레일에 일정한 간격으로 설치된 크로스아암은 부상제어기에 외란으로 작용한다. 부상제어기 제어대역 근처에 있는 외란으로 부상공극제어에 악영향을 미친다. 그 영향을 분석하여 제어기를 재설계하거나 크로스아암 간격을 조절하는 조치를 취해야 한다. 우선 부상제어 기를 제안하고 크로스아암외란을 입력으로 부상공극 출력 전달함수를 구해서 보드선도를 그려 그 영향을 분석한다.

  • Human body structure can be considered as a complex of many elements such as head, chest, arm, leg and etc. As the correct classification of human body is basic for the design of all the materials used by mankind and since we cannot consider all the elements simultaneously, there is a need of extracting a Sew elements which can be "most" representative of all those elements. This paper describes the procedure of determining those representative body dimensions utilizing the data obtained from a national project carried out in 1976. Also the relationship of the above determined body dimensions to the other commonly reference body dimensions are given in linear forms.ear forms.

  • In this paper, methods for computing the time-optimal motion of a robotic manipulator are presented that considers the nonlinear manipulator dynamics, actuator constraints, joint limits, and obstacles. The optimization problem can be reduced to a search for the time-optimal path in the n-dimensional position space. These paths are further optimized with a local path optimization to yield a global optimal solution. Time-optimal motion of a robot with an articulated arm is presented as an example.

  • The Direct Arm(DDA) is a SCARA typed direct drive manipulator with three degree of freedom(DOF) using the direct motor of the NSK company. In the paper, we propose a convenient interface for the SCARA-type robot which is practical to use. The proposed Visual Robot Teaching Mode using 3D graphics replaces the current teaching box. And besides this graphical teaching software can be implemented on the PC which is company used as a robot controller. This program was developed for the Windows 95 OS.

  • In this Paper, the design of a feedback linearization controller using multilayer neural network is proposed. The Proposed feedback linearization control scheme is designed by finding Lie derivatives from an identified neural networks. Lie derivatives are expressed as a combination of weights and neuron outputs. The proposed method is applied to an antenna arm problem and the simulation results show performance comparisons between the ordinary feedback linearization and the Proposed method.

  • This paper deal with the solution of kinematics and inverse kinematics of industrial FANUC robot by the bisection method with IBM PC 386. The inverse kinematics of FANUC robot cannot be solved by the algebraical method, because arm matrix T$_{6}$ is very complex and 6-joint angles are associated with the position and the approach of end-effector. Instead we found other 5-joint angle by an algebraical method after finding .theta.$_{4}$ value by a bisection method.d.

  • In this paper, a motion control algorithm is proposed by using neural network system, which makes a robot arm successfully avoid unexpected obstacle when the robot is moving from the start to the goal position. During the motion, if there is an obstacle the vision system recognizes it. And in every time the optimization-algorithm quickly chooses a motion among the possible motions of robot. The proposed algorithm has a good avoidance characteristic in simulation.
