Abstract

In this paper, a human coexistence-type companion robot that can communicate with people in daily life and alleviate the gap in care personnel was studied. Based on the voice recognition module, servo motor, and Arduino board, a companion robot equipped with a robot arm control function using voice recognition, a position movement function using RC cars, and a voice recognition function was tested and manufactured. As a result of the experiment, the speech recognition experiment according to distance showed the optimal recognition rate at a distance of 5 to 30 cm, and the speech recognition experiment according to gender showed a higher recognition rate in the first tone, monotonous tone. Through the evaluation results of these motion experiments, it was confirmed that a companion robot could be made.

본 논문에서는 일상생활에서 사람과 교감하며 돌봄 인력의 공백을 완화할 수 있는 인간 공존형 반려 로봇을 연구하였다. 음성인식 모듈과 서보모터, 아두이노 보드를 기반으로 음성인식을 이용한 로봇팔 제어기능, RC카를 활용한 위치 이동 기능, 음성인식 기능을 활용하여 도트 매트릭스를 이용한 반려 로봇의 감정표현 기능을 탑재한 반려 로봇을 실험, 제작하였다. 실험 결과로 거리에 따른 음성인식 실험 결과 5~30cm의 거리에서 최적의 인식률을 보였고 성별에 따른 음성인식 실험 결과에서는 남성의 인식률이 더 높은 것을 확인할 수 있었으며 성조에 따른 음성인식 실험 결과 첫 번째 성조인 단조로운 톤에서 높은 인식률을 보였다. 이러한 동작 실험에 대한 평가 결과를 통해 반려 로봇을 만들 수 있음을 확인할 수 있었다.
