This paper represents the mobile robot control system remote controlled by PDA(personal digital assistance). So far, owing to the development of internet technologies, lots of remote control methods through internet have been proposed. To control a mobile robot through internet and guide it under unknown environment, We propose a control method activated by PDA. In a proposed system, PDA acts as a user interface to communicate with notebook as a controller of the mobile robot system using TCP/IP protocol, and the notebook controls the mobile robot system. The information about the direction and velocity of the mobile robot feedbacks to the PDA and the PDA send new control method produced from the fuzzy inference engine.

In this paper, we developed a Windows 98 version Off-Line Programming System which can simulate a Robot model in 3D Graphics space. 4 axes SCARA Robot (especially FARA SM5) was adopted as an objective model. Forward kinemat-ics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the OLP system in the Windows 98s GUI environment was also studied. The developing is Microsoft Visual C++. Graphic libraries, OpernGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

In this paper, we supposed teller following algorithm that using sound localization for developing dialog type humanoid robot. A sound localization is studied for develop the techniques of an efficient 3-D sound system based on the psychoacoustics of spatial hearing with multimedia or virtual reality. When a robot talk with human, it is necessary that robot follow human for improved human interface and adaptive noise canceling. We apply this algorithm to robot system.

This paper deals with the design and the realization of a small humanoid robot, which is called SERO_VI. The design concept and the mechanical structure including kinematics for the robot are presented. The humanoid robot consisted of 25 DOF with legs 12 DOF, arms 8 DOF, waists 3 DOF and heads 2 DOF for the purpose of vision system. The controller structure was also suggested such as modular joint actuators, DSP interface and their communication method. Simple experiment was done and its validness was investigated in order to verify the kinematic result.

This paper propose a control network system based on IEEE1394 for a multi body robot control. The IEEE1394 has the characteristic of high speed(400Mbps), real-time, stability and plug&play. And IEEE1394 also supports freeform daisy chaining, branching and hot plugging, which reduce cabling complexity and make a system simple. Especially, multi host and broad casting support network data sharing method which is suitable for control network for multi body robot. Through experiment, we show that the proposed control network can interface 48 joints (BLDC motors, gears, and encoders) and four 6-axis force/torque sensors with 4Khz communication bandwidth, which is adequate for a multi body robot.

In this paper, we have developed a Widows 98 version Off-Line Programming System which can simulate a Robot model in 3D Graphics space. The SCARA robot with four joints (FARA SM5)was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the OLP system in the Widows 98's GUI environment was also studied. The developing language is Microsoft Visual C++. Graphic 1ibraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

In recent years, a number of robot work measurement systems have been developed. This study discusses CARS (Computer Aided Romum System) which is to computerize the existed manual version ROMUM (RObot Modularization of the Unit Motion) method as the predetermined time system for robot work measurement. The ROMUM was developed to establish the standard time of work through modularize the unit motions in robot tasks. The CARS is designed on a menu driven form by computer assist for user interface and then interacts with user effectively. Therefore, the system can provide the convenience of use and minimization of analysis time and degree of judgement for establishing standard time.

This paper described a novel locomotion interface that can generate infinite floor for various surface, named as virtual walking machine. This interface allows users to participate in a life-like walking experience in virtual environments, which include various terrains such as plains, slopes and stair ground surfaces. The interface is composed of two three-DOF (X, Y, Yaw) planar devices and two four-DOF (Pitch, Roll, Z, and relative rotation) footpads. The planar devices are driven by AC servomotors for generating fast motions, while the footpad devices are driven by pneumatic actuators for continuous support of human weight. To simulate natural human walking, the locomotion interface design specification are acquired based on gait analysis and each mechanism is optimally designed and manufactured to satisfy the given requirements. The designed locomotion interface allows natural walking(step: 0.8m, height: 20cm, load capability: 100kg, slope:30deg) for various terrains.

Recently, various inpipe inspection robots are developed and its effective values are increased in industrial use. However, it is so difficult to make a inpipe inspection robot system which has flexible mobility and accuracy of inspection in pipelines. Especially, it is very important to know the exact crack position. In this paper, we are to present a lately developed inpipe inspection robot system which can resolve the above Problems. The robot is configured as an articulated structure like a snake. Two active driving vehicles are located in front and rear of the inspection robot respectively and passive modules such as a nondestructive testing module and a control module are chained between the active vehicles. Special feature of the robot system is a ground interface, which is able to show informations of robot and pipelines. By using this, so called virtual map in this paper, user is able to know the pipelines'feature and crack position.
