Abstract
본 논문은 자율주행차량과 로봇의 안내를 위한 새로운 자계위치인식방법을 제안한다. 차량 및 로봇이 자율주행을 하기 위해서는 이동경로상의 현재 위치를 인식하는 것이 기본적으로 요구된다. 자계기반 자율주행차량과 로봇은 자성체로부허 발생되는 자계를 계측하여 위치정보를 검출한다. 이러한 자계위치인식시스템에서 지구자계는 기본적인 왜란으로 작용한다. 본 논문에서는 지구자계의 영향을 제거하기 위해 다수의 1축 자계센서 열을 구성하였으며, 자계센서 출력의 선형동작영역을 이용하여 정밀한 위치인식시스템을 개발하였다. 제안하는 방법이 자율주행차랑과 로봇의 안내를 위해 사용 가능함을 실험을 통하여 검증하였다. In this paper, a new magnetic position sensing mettled for autonomous vehicle and robot guidance is presented. In autonomous vehicle and robot control, position sensing is an important task for the identification of their locations, such as the current position within a trajectory. The magnet based autonomous vehicle and robot was identified position via magnetic materials. In the magnetic sensing system, the Earth field is one of the largest disturbance. To removal of the Earth field, this paper proposes 1-dimensional magnetic field sensors array and develops precise petition sensing system using linear operating region of the magnetic field sensor. This proposal is verified a feasible magnetic position sensing system for autonomous vehicle and robot guidance by the experimental results.
