초록

본 논문에서는 지자기센서와 스마트폰을 사용하여 개인이동시스템(PMS)을 구현한다. 지자기센서를 사용한 PMS 제어 시스템은 탑승자가 원하는 방향으로 스마트폰을 향하게 하면 PMS는 탑승자가 원하는 방향으로 이동한다. 본 논문에서 제안한 스마트폰 제어 PMS는 지자기센서를 사용함으로써 버튼 조작에 의한 제어보다 더 직관적으로 PMS를 제어하므로 사용자에게 더욱 편리한 인터페이스를 제공한다. 그리고, PMS에 장착된 모터의 기계적 특성을 보정하기 위하여 지자기센서가 사용되었다. 또한, 본 논문은 지자기센서 기반의 PMS의 제어방법으로 절대방향과 상대방향 제어방법을 제안한다. 실험 결과로서 제안된 두 가지 방법으로 지자기센서 기반의 PMS가 편리하고 효과적으로 제어되었다.

In the paper, a smartphone-controlled personal mobility system(PMS) based on a compass sensor is developed. The use of a magnetic compass sensor makes the PMS move according to the heading direction of a smartphone controlled by a rider. The proposed smartphone-controlled PMS allows more intuitive interface than PMS controlled by pushing a button. As well, the magnetic compass sensor makes a role in compensating for the mechanical characteristics of motors mounted on the PMS. For adequate control of the robot, two methods: absolute and relative direction methods based on the magnetic compass sensor and wireless communication are presented. Experimental results show that the PMS is conveniently and effectively controlled by the proposed two methods.
