오늘날 네비게이션 시스템이 대부분의 차량에 필수장비가 될 정도로 GPS는 우리도 모르게 많이 사용되고 있고 많은 연구가 진행되어 있다. 그러나 대부분 차량용 네비게이션은 도로의 정보를 통하여 GPS의 불확실한 정보를 보정하게 되지만 도로정보를 참조할 수 없는 해상이나 공중에서 사용하기 위해서는 보정이 어려운 것이 사실이다. 본 논문에서는 이동로봇에 대하여 일반 도로가 아닌 개활지에서의 자율주행을 목표로 한 시스템을 개발하였다. 연구내용으로는 NXT 로봇과 Compass Sensor, 그리고 Bluetooth GPS를 이용하여 도로의 정보가 없이 로봇의 위치를 보정하였고, 목표점까지의 거리와 각도를 계산한 후 자율 주행이 가능하도록 LabView로 프로그래밍 하였다. 결과적으로 NXT 로봇의 목표지점간 최적이동 알고리즘을 구현하였고 실험을 통하여 이를 증명하였다.

We propose to design and to implement a recreational and end - of - play robot for symptom relief in patients with depression. The main symptom of depression is the loss of interest and interest in life. The depression diagnosis patient confirms the emotional analysis revealed by his / her robot through the robot, and performs the greeting or ending play. After analyzing the emotions in the expressions after the play, the function of the embodying robot is confirmed by receiving the report. A simple play can not completely cure a patient with a diagnosis of depression, but it can contribute to symptom relief through gradual use. The design of the play-by-play robot is using Q.bo One, an open-source robot that can interact with Thecorpora. Q.bo One's system captures a user's face, takes a picture, passes the value to the Azure server, and checks the emotional analysis before and after the play with the accumulated data.Play is implemented in Rasubian, the OS of Q.bo One, using the programming language Python and interacting with external sensors. The purpose of this paper is to help the symptom relief of depressive patients in a relatively short time with a play robot.

Robot control and image processing using a smartphone and Wi-Fi communication is introduced. The robot has a wheel and quadruped mechanism that is transformed according to the environment and is mainly used for drug bottle delivery. The captured image on the camera is transmitted to the smartphone in the form of stream data, and the image data is processed in the smartphone to enable the robot to identify an object and to control the robot itself. A network was constructed so that only image data from the stream data was used, and an image processing scheme to identify the drug bottle and deliver it to a person using a robot arm is also presented. In this study, image processing techniques and algorithms were purely implemented on a smartphone with considerable computational power and multiple functions rather than a computer, which contributes to the intelligence and miniaturization of the robot system.

It is a key role in leading and activating coding education as a process to solve problems creatively to produce and provide the educational contents on the basis of 3D printing. In this paper, we develop a variety of fusion contents to use 3D printing and 8bit MCU base control board which provides specific functions through Arduino. The developed control program conducts various packet monitoring more than ten times per a second, supporting intrinsically full duplex. In addition, communication protocol optimized in conveying a lot of information enables to control different contents. The contents produced with the control board and 3D printing are useful as a programming education tool to train the principle and the concept of coding.
