The present study was carried out in order to develop a remote-controlled micro ornithopter with a weight of 20 gram. This ornithopter has three channel radio control. It runs on two direct-current type pager motors powered by a lithium polymer battery which flaps its 35cm wings. The performance of an ornithopter, applied to a flapping motion only, was validated by flight tests. The flight test results indicate that the ornithopter developed here has sufficient thrust to propel itself.

본 논문은 DC모터와 Bluetooth모듈을 통해 직접 조종하여 움직이는 알람시계 형태로 로봇을 제작하여 단순한 알람시계가 아닌 재미와 편의를 제공하는 알람시계 로봇을 제안한다. Arduino Uno 보드(ATmega328 기반의 마이크로컨트롤러 보드)와 DC모터를 이용한 로봇 본체, 스마트폰과 통신하는 bluetooth모듈, 로봇을 작동하는 어플리케이션 등으로 구성된다. 알람이 작동되면서 랜덤하게 움직이는 로봇은 블루투스 통신으로 제어가 되고 사용자의 조종에 따라 움직인다. 로봇은 스마트폰과 블루투스 통신을 통해 받은 데이터로 조종되어 지정된 도착장소로 움직일 수 있다. 이러한 로봇을 제작하여 실생활에 상용화 가능하게 만들어 또 하나의 아이디어 알람시계가 되고자 하는 목표를 가진다.

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.

To obtain large scale precise geographical information in local area we determined external orientation parameters of camn exactly and conducted aerial photography using remote control airship loaded 35mm non-metric camera that produced systematic error coefficients. Ground control Points were determined by differential GPS. Therefore we can try to improve accuracy and economical efficiency. Also, it is suggested that remote control airship photogrammetry can be applied to make large scale topographic map using analytical plotter as calibrated accuracy.

Due to the development of drones, drone missions are performed in various fields, and BVLOS (Beyond Visual Line Of Sight) flight is performed in a wide area. Most drones operate through radio frequency (RF) communication and can only fly in a limited radius of about 1-2 km. To overcome this, in this paper, we propose a multi-communication protocol-based drone control system to control drones performing missions in BVLOS using RF and LTE (Long Term Evolution). The proposed system consists of a control unit and a drone unit. The control unit transmits one control signal generated from the remote controller through RF and LTE. The drone unit classifies the control signal transmitted through RF and LTE according to the priority of the communication protocol and delivers it to the FC (Flight Controller). Through the proposed control system, it is possible to overcome the RF communication distance limit and prevent the communication disconnection situation.

Avionics technologies have been developed with a development of an airplane since 1903. Historically, radio communication was started in 1910's, radio navigations in 1920's and autopilot was applied first in 1930's. Glass cockpit was initiate on MD-80 in 1979 first and now spreaded widely and similar with GPS navigation. Avionics in modern aircraft has a great deal of importance in view of flight safety and maintaining comfortableness. As avionics develops, so do the certification technologies. This paper introduces update avionics certification technologies developed recently.

An unmanned speed sprayer was developed using a remote control and an inductive cable guidance systems to protect operators and environment from hazardous pesticides. The sprayer consists of a remote control system, an induction system, obstacle detectors, control actuators and an one-chip microcomputer. The sprayer can be operated by the induction guidance and/or remote control. The following summarize characteristics of the developed speed sprayer. 1) Both the remote control and the induction guidance operation were possible with the developed speed sprayer. 2) Sixteen functions of the forwarding, backing, halting, steering, 3-way valve for nozzles and fan operating etc. were utilized on the remote control system. 3) It was concluded that the DTMF method, having less transmitting error, performed better than the FSK method for an agricultural remote controller. A radio station may be necessary. 4) The digital inductive guidance system, consisting of five low-impedance detection coils and a window comparator circuit, performed better than the analog detecting system, guiding route using inductive voltage differential from tow detection coils.
