초록

종합 설계 교과를 이수하고 성과 결과물로 졸업 조건 만족하기 위한 작품제작이 연결되는 전공중심의 학습활동을 통해 공학교육의 실천 방안을 제시한다. 설계 구성된 주제는 초음파 센서의 장애물 감지 기능을 이용하여 주행 도중 최소 안전거리를 측정하고, 가속도 자이로 센서의 측정값을 기반으로 회피 알고리즘을 수행하는 것으로 한다. 드론과 주변 사물, 사람의 피해를 최소화하며 공중 이동 성능을 향상 시키는 접근 감시 시스템을 제안한다. 실험 결과 5개의 초음파센서를 통해 드론 주변의 장애물을 감지하며, 드론 각각의 모터에 출력값의 차이가 적용되고, 장애물 회피를 확인하였다. 또한 공학교육인증 프로그램의 학습성과 성취도 측정을 위한 자료의 내용과 수준으로 과정에서 얻어진 결과를 사용하였고, 4년제 공과대학 졸업예정자에게 요구되는 공학문제수준설명에 부합함을 확인하였다.

This study will provide a practical plan of engineering education through the study of major activities connected with the production of works to accomplish the graduation conditions by completing the comprehensive design subject and the result of the performance. The designed subject is to measure the minimum safety distance during driving using the obstacle detection function of the ultrasonic sensor and to perform the avoidance algorithm based on the measurement value of the acceleration gyro sensor. It is proposed an access surveillance system that minimizes the damage of drones, surrounding objects, and people, and improves air mobility. Experimental results show that the obstacles around the drone are detected by five ultrasonic sensors and the difference of output value is applied to each motor of the drone and obstacle avoidance is confirmed. In addition, the content and level of the data for measuring the achievement of learning achievement in the engineering education certification program were used and the results were confirmed to be consistent with the description of the engineering problem level required for the graduates of 4-year engineering college.
