Currently offshore fisheries are one of shrinking industries and fishermen are getting older. Moreover it is difficult to work fisheries for decreasing fishermen as the time goes. Two people per a boat work together at least for proper fisheries. If the unskilled fisherman boards on boat, it will make some troubles to speak each other and diminish the efficiency of working because one person should control the boat. So it need to study the remote control system for leasure and outboard engine that can control and work at the same time. The remote control system is consisted of engine, steering gear and forward reverse neutral gear controls. These three controls are made by position and speed control using DC motor, and microcontroller is used to control the engine speed and rudder angle. This system can be controled and worked alone and we tested the system at sea and confirmed that the system works properly.

본 논문은 원격 제어기가 CCD 카메라를 이용해 이동로봇의 상태를 파악해서 무선으로 이동 로봇을 제어하고, 사용자는 인터넷을 통해 원격 제어기와 통신하면서 이동로봇을 조종하여 이동로봇이 장애물을 피해 가면서 원하는 위치까지 이동할 수 있게 하는 알고리즘을 제안한다. 제안하는 알고리즘인 Land Gambling DT를 통해 일단 경로계획을 하고 생성된 경로를 따라 이동로봇이 이동 중 장애물이 있는 경우 VFH를 이용하여 장애물을 피해 가는 것이다.

육상의 원격제어자가 선박을 제어할 때 가상의 모형선박이 같이 조종되도록 하여, 운전상태의 확인을 도울수 있도록 하고, 시험운항시 에뮬레이터를 선박에 연결하여 원격운전데이터의 시각적 확인이 될수 있도록 하였다. 또한 이더넷의 디지털데이터가 아날로그로 변환된후 커넥터로 케이블을 연결할수 있도록 하여, 아날로그 인터페이스를 가진 선박의 장비가 제어가 될수 있는 예시를 보여준다.

This paper describes a development of an network based remote surveillance system using omni-directional mobile robot. the proposed surveillance system can control a mobile robot to move and examines the given place closely while the conventional surveillance system uses a fixed camera. The mobile robot in the proposed system has three omni-directional wheels to move to any given direction freely. We also developed the proposed system as robot services using Microsoft's MSRDS for a user to control the mobile robot and monitor the remote scene captured from the robot. Finally we verified the feasibility and effectiveness of the proposed system by conducting the remote operating the mobile robot and monitoring experiments in a networked environment. We also conducted a color based object detection and motion detection on image sequences acquired from a remote mobile robot in an another PC in a network environment.

The power plants have a loading dock and unloading device for the diverse kinds of fuel such as the bituminous coal and natural gas imported by the sea from all over the world. To unload the coal in the ship not only in the environment-friendly manner but also in the cost-effective way, the new type of heavy equipment loaded with additional features as well as excavator and the remote controller to maneuver this equipment are developed. This heavy equipment, which can be used to unload the coal in the ship in conjunction with CSU (Continuous Ship Unloader), and the remote controller are endorsed by the related code and laws. With the remote controller, the field workers can operate the unloading equipment at the remote place far from the equipment as well as in the cabin for themselves without tile remote controller.

In this paper, to improve the variable and remote controllable digital power-supply design. It is able to RS-232 communication for remote control. And it can also observe the correct power. Finally, it intend to high ratio design that compare input power with output power. There are especially useful solution in korea to be under the unstable voltage environment.

최근 다양한 센싱장치와 HCI 디바이스를 결합하여 로봇이나 기계장치를 구동하려는 연구가 활발하게 진행되고 있다. 또한 기존의 RC방식의 무인비행체 조작은 관련분야의 전문성을 필요로 할 만큼 접근하기 어려운 면이 있었다. 이에 본 논문에서는 소형 무인비행체(UAV)의 움직임 제어를 위해 데이터 글로브의 손가락 구부러짐을 인식하여 이를 통해 무인비행체를 조작하는 원격조종장치에 관한 시스템 구조 및 프로토콜을 제안한다. 이 시스템을 통해 비전문가로 하여금 무인비행체의 접근성을 높이며 다양한 분야에 활용 할 수 있는 가능성을 제시하고자 한다. 이를 위해 데이터 글로브의 센싱 데이터에 대한 조합 및 해석방식을 정의하고, 이를 데이터 글로브의 손가락 구부러짐 해석에 적용하였다. 또한 조합된 명령신호를 전송하는 무인비행체의 구동 제어를 위한 비동기 Uplink 프로토콜을 제안하였다.
