A method for the design of a disk cam with a remote follower is presented. ADAMS software is utilized for the design process. The whole process is applied for the design of a cam profile to be used in a tappet shedding device of a shuttle loom. First the desired motion of the remote follower, the hearld frame in this case, is determined to improve the characteristic of a certain weaving process. Next, the desired displacement data is input to the ADAMS software and the cam profile is obtained as an output. To test the validity of the proposed method, designed cams were actually manufactured and implemented on a experimental loom. And with the help of potentiometer type displacement transducers, the motion of the remote followers were actually recorded. And the result was sufficient to prove the validity of the presented method.

The virtual reality - haptic device is developed for the purpose used in the work that human cannot approach and that need elaborate exercises. To render haptic, the total system is constituted master, haptic device, and slave, remote manipulator. Human operates the remote manipulator. Human operates the remote manipulator relying on the hapti devices and stereo graphic. And then the force and scene of the remote manipulator is fed-back from each haptic devices and virtual devices. The feedback information gets system gain exactly. The system gain provides the most exact haptic and virtual devices. The feedback information gets system gain exactly. The system gain provides the most exact haptic and scene to human by the location, the graphic rendering and the haptic rendering algorithm on real-time. In this research, 3D haptic device is developed for common usage and make human feel the haptic when human contacts virtual object rendered by computer graphic. The haptic device is good for tracing location and producing devices because of the row structure. Also, openGL and Visual Basic is utilized to the algorithms for haptic rendering. The haptic device of this research makes the interface possible not only with virtual reality but also with the real remote manipulator.
