This paper describes the results of a study on the unmanned cleaning robot that performs the cleaning of the floating photovoltaic panels. The robot uses two SSC (Sliding Suction Cup) adsorptive devices to move up and down the slope. First, the forces generated when the robot moves up the slope are mechanically analyzed. The robot was designed and manufactured to operate stably by using the presented results. Next, the robot motion was tested on the inclined panel. It has been proven that robots are well designed and built to clean sloped panels.

We developed a biofeedback gait training system; a 12 m measuring walkway with a training walker which moves at prescribed velocity. The walkway measures a.11 temporal and distance factors of gait. This system provides visual feedback for distance factors and auditory one for temporal at the prescribed walking velocity. Experiments were performed on normal and degenerative knee joint subjects, and this system was verified to be very useful.

We proposed a new variant of correlation approach for ARMA model. The proposed method is is intended to make the current prediction error uncorrelated with the past one. In the investigation of the properties, the uniqueness, consistency and asymptotic normality of the estimate are shown. Via simulation results, we show that the proposed method give good estimates for various systems.

In this study, we investigated the modeling and design of an Intelligent Agent System (IAS). To achieve this goal, we introduced several kinds of agents that exhibit intelligent features. These are the main agent, management agent, watcher agent, report agent and application agent. We applied the intelligent agent concept to two different application fields, i.e. the intelligent agent system for pattern classification and the intelligent agent system for bank asset management modeling.

In this paper we are concerned with optimal control problems whose costs am quadratic and whose states are governed by linear delay equations and general boundary conditions. The basic new idea of this paper is to Introduce a new class of linear operators in such a way that the state equation subject to a starting function can be viewed as an inhomogeneous boundary value problem in the new linear operator equation. In this way we avoid the usual semigroup theory treatment to the problem and use only linear operator theory.

In this paper, a robot system is proposed to make it easy to learn about microprocessors. The proposed system consists of several subsystems. Since each subsystem can be operated with other subsystems or without other subsystems, many microprocessor courses can be offered depending on the background of students. Also the proposed system can be used in some robotics courses which emphasize sensor and tele-operation because it contains camera, MPEG encoder, IR sensor, and RF communication module.

The welding technology must fit to the purpose of each construction. The includes a careful understanding of demands, the adapted materials and their behaviour subjected to welding. The manufacturing is very essential too. The education of welding and control personnel will change. The integration of robotics, sensing and automation in the production makes the role of personnel and their responsibility very different. The paper tries to give the state of the art and an estimation for this and possibly the next decade(Fig. 1)

Many countries and international organizations have carried out rover missions to explore planetary surfaces. Accordingly, the demand for mechatronics education, which is closely related to building exploratory robots, is also steadily increasing. However, due to the complexity in understanding the background information needed for mechatronics, it is hard for pre-college students to study such process. In this study, we suggest an educational platform for mechatronics using a combined robot kit with a spherical robot and a smartphone application. To provide a visual understanding, the dynamic model of the robot is constructed while analyzing the error between actual driving and a simulation, and the educational algorithm of the game and a feedback method are proposed to improve the learning efficacy by considering the user's level of knowledge of mechatronics. We use this educational spherical robot to develop a curling game platform that can impart engineering education even when students lack significant knowledge.

The purpose of this study was to propose conceptual Structure of the study of industrial education based on the concepts and characteristics of industrial education. Therefore, the study was conducted through literature research. 1) The characteristic of industrial education in the study was proposed as 'subject for occupational competence in the industrial technology' on the educational purpose. 2) The characteristic of industrial education in the study was proposed as 'subject for practical knowledge in the industrial/engineering technology' on the structure of knowledge. 3) The characteristic of industrial education in the study as was proposed as 'subject for technological problem solving in the system design and engineering context' on the educational methodology 4) The characteristic of industrial education in the study was proposed as 'design, building, testing and troubleshooting' on the educational process.

This paper is concerned with the reliable $H_{\infty}$ controller design problem for uncertain linear systems against actuator failures. In the design, the $H_{\infty}$ performance of the closed-loop system is optimized during normal operation(without failures) while the system satisfies a prescribed $H_{\infty}$ performance level in the case of actuator failures. Single and parameter-dependent Lyapunov function approaches are applied in designing suboptimal reliable $H_{\infty}$ controllers. Simulation studies are presented to demonstrate the effectiveness of the proposed design procedures.
