Abstract

A campus guide robot was developed that can autonomously guide people through a university campus. The robot is able to evaluate its location using Differential Global Positioning System (DGPS) and Dead-Reckoning using the encoders mounted on its wheels. The robot can navigate autonomously along a guide route that is set in advance. A new position-based guidance approach was suggested. Unlike the conventional method of setting the guide sequence in advance, the robot acquires guidance by judging whether there is guide information corresponding to its current position. The robot searches guide information from the guide database while it moves along the guide path autonomously. If there is any guide information available around the location of the robot, then it performs guide functions. We also suggested an effective guide scenario that can maximize the interest of people. The performance of the robot was tested through sets of experiments in a true campus environment.

캠퍼스를 자율적으로 주행하면서 내방객을 안내하는 안내로봇을 개발하였다. 이 로봇은 DGPS와 로봇 바퀴에 부착된 엔코더 정보를 이용하여 자신의 최적 위치를 평가하여 사전에 설정된 안내경로를 자율적으로 주행하면서 안내를 수행한다. 본 연구에서는 안내할 정보를 미리 순서대로 설정하는 기존 방법과 달리 이동 중 자신의 현재 위치를 평가하고 그 위치 주변에 안내할 정보가 있으면 그 정보를 이용하여 안내를 수행하는 위치기반 안내방법을 제안한다. 또한 안내효율을 극대화 할 수 있는 안내시나리오 구성방법을 제시한다. 개발된 안내로봇의 성능을 실제 캠퍼스 안내에 적용하여 평가하였다.
