In this paper we implement a robot system consisted of mobile tole robot to be controlled by client through web browser Newly Internet is connected to all network of the whole world. If client uses the network like this, client can control direction of a robot that is selected in free place. In this study, system is embodied in using robot that can move freely in plan place and cod camera that can grab robot image. System transmit image data of cod camera to java server that is placed in web server of internet that is used by client. Java server display incoming data in home page using java applet. Then web browser offer robot image to client and client send remote control signal to robot. Control signal is transmitted to robot by java server and robot receiving signal moves toward direction wanted by client.

최근의 프로그래밍 패러다임은 객체지향프로그래밍과 이를 기반으로 하는 비주얼프로그래밍이 주류를 이루고 있다. 그러나 객체지향프로그래밍은 기존의 구조적프로그래밍기법에 비하여 개념이 어렵고 복잡하여 IT 관련학과 학생들을 교육하기에 어려움이 많았다. 본 연구에서는 학생들이 다양한 입출력 장치를 부착하고 로봇제어가 가능한 트레이닝 키트를 사용하여 객체지향 프로그래밍 학습 의욕 고취와 동기를 유발할 수 있도록 Java 가상머신을 내장한 Java 로봇 트레이닝 키트를 설계하고 구현하였다. 개발된 Java 로봇 트레이닝 키트는 USB 인터페이스로 컴퓨터와 통신 가능하며, 다양한 입출력 장치와 DC 모터 및 서보모터를 구동할 수 있는 범용 입출력 포트를 내장하여 교육용 로봇제작과 응용프로그래밍 실습이 가능하다. 따라서 IT 융합시대를 맞이하여 학문과 전공간의 벽이 낮아지고 창의 공학적 객체지향 프로그래밍언어 교육의 도입이 필요한 시점에서 본 연구에서 개발한 Java 로봇 트레이닝 키트가 많은 기여를 할 것으로 기대된다.

본 연구에서는 Atmel사의 AVR 마이크로프로세서에 적합하게 개발된 Java 바이트코드 인터프리터인 NanoVM을 자체 개발한 마이크로로봇에 이식하여 Java 언어 전용 로봇을 구현하였다. 따라서 마이크로프로세서의 구조와 회로를 모르는 학생들도 로봇을 프로그래밍하면서 Java 언어를 효율적으로 학습할 수 있다. 더욱이 최근 학생들의 프로그래밍언어 학습 능력이 떨어지면서 컴퓨터 관련학과의 프로그래밍언어 교육이 많은 어려움을 겪고 있다. 따라서 학생들의 프로그래밍언어 학습 동기를 부여하고 창의 공학적 프로그래밍언어 교육프로그램의 도입이 필요한 시점에서 본 연구에서 개발한 Java 로봇은 많은 기여를 할 것으로 기대된다.

The teleoperation system applies all of the industrial fields due to the development of the network infrastructure. It is one of the indispensable elements for controlling the robot at a remote sight and monitoring the limit or unknown environment. The common teleoperation robot system is what has the visual module to supply the network system and realistic UI to the existed robot system. Therefore, remarked that the fusion between modules and transmission of visual data the remarked the important element to improve the robot application in the various environments. Delay of development time by robot platform and noneffective communication among developers are also problem to approach. In this paper we propose the independent teleoperation system. The main application language is JAVA in this system, which is applied JAVA API like JNI and JMF to construct the effective teleoperation system. The system has the both side communication system between sever and client as a basic structure. The visual data that is attached the robot at a remote sight is captured by JMF API and then is transmitted to the web browser called client by RTR protocol. JNI is used to connect between JAVA and the lower part application (sensor fusion, motion control.) of the robot programmed by various Native languages. The proposed system is the application that can perform the elements, for instance transmission of visual data, the fusion of various native application modules and the effective network communication, with any platform.

C 언어는 AVR사의 ATmega128을 기반으로 하는 교육용 로봇 팔의 주 프로그래밍 언어다. C 언어는 교육용 로봇 팔을 제어하고 프로그램 학습하기 원하는 중학교 또는 고등학생들에게는 매우 어렵고 복잡하였다. 더구나, 통합개발환경, 디버딩 및 테스팅 환경도 제공하지 못하였다. 본 연구에서는 이러한 문제를 해결하기 위하여 교육용 로봇을 위한 자바 기반의 통합 개발 플랫폼을 제안하였다. 이 플랫폼은 교육용 로봇 팔을 위한 최신의 초소형 자바 가상 머신(NanoVM), 이클립스 플러그인을 사용한 통합개발환경, 실제 로봇을 연결하지 않아도 테스트 및 디버깅을 할 수 있는 3차원 시뮬레이터를 포함하고 있다. 이러한 자바 개발환경은 어린 학생들이 매우 용이한 교육용 로봇 팔 학습환경을 제공하게 되었다.

This paper proposes a remote control system that combines computer network and an autonomous mobile robot. We control remotely an autonomous mobile robot with vision via the internet to guide it under unknown environments in the real time. The main feature of this system is that local operators need a World Wide Web browser and a computer connected to the internet communication network and so they can command the robot in a remote location through our Home Page. The hardware architecture of this system consists of an autonomous mobile robot, workstation, and local computers. The software architecture of this system includes the server part for communication between user and robot and the client part for the user interface and a robot control system. The server and client parts are developed using Java language which is suitable to internet application and supports multi-platform. Furthermore, this system offers an image compression method using motion JPEG concept which reduces large time delay that occurs in network during image transmission.

This paper presents a robot system that combines computer network and an autonomous mobile robot where RTOS is installed. We propose a wireless communication protocol, and also implement it on the RTOS of the robot system. Main controller of the robot processes the control program as a task type in the real-time operating system. Peripheral devices are driven by the device driver functions with the dependency of the hardware. Because the client and server program was implemented to support the multi-platforms by Java SDK and Java JMF, it is easy to analyze programs, maintain system, and correct the errors in the system. End-user can control a robot with a vision showing remote sight over the Internet in real time, and the robot is moved keeping away from the obstacles by itself and command of the server received from end-user at the local client.

Until now, many networked robots have been connected to the Internet for the various applications. With these networked robots, very long distance teleoperation can be possible through the Internet. However, the promising area of the Internet-based teleoperation may be distance learning, because of several reasons such as the unpredictable characteristics of the Internet. In robotics class, students learn many theories about robots, but it is hard to perform the actual experiments for all students due to the rack of the real robots and safety problems. Some classes may introduce the virtual robot simulator for students to program the virtual robot and upload their program to operate the real robot through the off-line programming method. However, the students may also visit the laboratory when they want to use the real robot for testing their program. In this paper, we developed an Internet-based robot education system. The developed system was composed of two parts, the robotics class materials and the web-based Java3d robot simulator. That is, this system can provide two services for distance learning to the students through the Internet. The robotics class materials can be provided to the student as the multimedia contents on the web page. As well, the web-based robot simulator as the real experiment tool can help the students get good understanding about certain subject. So, the students can learn the required robotics theories and perform the real experiments from their web browser when they want to study themselves at any time.
