본 연구의 목적은 초등학교 교육과정에서 활용이 가능한 학습도구로서 프로그래밍이 가능한 로봇의 활용 방안을 알아보기 위함이다. 로봇은 다른 디지털 교구와는 달리 프로그래밍과 이를 통한 조작이 쉽다는 점에서 교수-학습목적의 차별화된 매체적인 특성을 갖는다. 이 연구에서는 초등학교 학생들에게 컴퓨터 프로그램의 핵심인 알고리즘을 가르치기 위한 도구로서 로봇게임프로젝트 개발을 통해 연구목적을 달성하고자 하였다. 본 연구에서 교구로 사용한 레고는 프로그래밍을 할 수 있는 환경을 갖추고 있으며, 중앙제어장치, 센서 및 모터세트를 기계적으로 조합하여 로봇을 만들 수 있다. 개발한 프로젝트는 학생들이 6차시 수업을 통해 3개의 과제를 해결하도록 하는 과정에서 이루어졌다. 이들 각각은 알고리즘의 기본적 원리들을 바탕으로 구성되었으며, 이 프로그램을 교실수업에 적용해 본 결과, 학생들이 상대적으로 학습의 즐거움을 경험하고 몰입의 효과가 나타났음을 알 수 있었다. 이러한 결과는 일반적인 초등학교 교실에서 직접 로봇을 조작하는 활동이 학교교육활동에 새로운 가능성을 가져올 수 있음을 보여준 것이라고 하겠다.

Many accidents related to robot operation occur during the robot teaching process. This paper deals with recommendations for the teach pendant design parameters to enhance safety and performances in human-robot interactions. In order to investigate the optimum location and the size of the emergency stop button on the teach pendant, an experiment was conducted with a simulated teach pendant which can accomodate four different locations and three sizes of the button. Under a simulated emergency condition, the reach time to the emergency stop button was measured at random combination of the location and the size of button. The reach time was significantly affected by the location and the size of the emergency stop button. The fastest average reach time was attained with 1.5 inch-diameter button on the upper center of the teach pendant.

In this paper we present the guideline to evaluate the easiness of using personal robots and their learning abilities based on the analysis of their built-in commands, user interfaces, and intelligences. Recently, we are breathing with robots that can be able to do lots of roles. cleaning, security, pets and education in real life. They can be classified as home robots, guide robots, service robots, robot pets, and so on. There are, however, no standards to evaluate their ability, so it is not easy to select an appropriate robot when a user wants to buy it. Thus, we present, as a guideline that can be a standard for the evaluation of the personal robots, the standards by means of analyzing existing personal robots and results of the recent research works. We will, also, describe how to apply the evaluation method th the personal robot.

Most of shoes manufacturing processes are not yet automated, it puts restrictions on increasing of productivity. Among them, adhesive application processes particularly are holding the most workers and working hours. In addition, its working conditions are very poor due to the toxicity of adhesive agents. In case of automating adhesive application processes by using robots, the robot teaching by playback is difficult to produce high productivity because the kinds of shoes to be taught mount up to several thousands. Therefore, it is essential to generate the robot working paths automatically according to the kind, the size, and the right and left of shoes, and also to teach them to the robot automatically ...

We propose a unmaned integrating control system based-on Windows XP version Off-Line Programming System which can simulate a Robot model in 3D Graphics space in this paper. The robot with 4 and 6 axes modeled SM5 and AM1 respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off-line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

This paper presents a simple identification method of the actual kinematic parameters for the robot with parallel joints. It is known that Denavit-Hartenberg's coordinate system is not useful for nearly parallel joints. In this paper, the coordinate frames are reassigned to model the kinematic parameter between nearly parallel joints by four parameters. The proposed identification method uses a straight ruler about 1m long. A robot hand is placed by using a teaching pendant at the prescribed points on the ruler, and corresponding error function is defined. The identified kinematic parameters which make the error function zero are obtained by iterative least square error method based on the singular value decomposition. In the compensation of joint angles, only the position is considered because the usual applications of robot do not require a precise orientation control.

In this paper, we propose action-learning method based on teaching. By adopting this method, we can handle an exception case which cannot be handled in an Ethology-based Action SElection mechanism. Our proposed method is verified by employing AIBO robot as well as EASE platform.
