Abstract

The purpose of this study was to derive the factors that affect the development cost and the priority/weight of effectiveness in the pre-development stage of a service robot to estimate the development cost. In particular, the functions of service robots vary according to the field of application, and their prices are not only different but most of them are small-scale production; hence, a cost estimation is necessary. In this research, the factors affecting the service robot development cost in the process of service robot development and adding functions are classified as a functional factor while the factors that affect the entire development cost due to environmental causes, in which the service robot is operated or in the development process, are classified as an adjustment factor. The FGI was conducted to derive the factors and a Delphi survey was conducted among 84 domestic experts to determine the weights of the factors. As a result of the analysis, six functional factors (41 detailed criteria) and five adjustment factors (17 criteria) were derived, the cost weight and rank of the factors were suggested. This study suggests that the development cost of the service robot can be used as a decision-making strategy to select the operation functions in the development process, and can be utilized as an essential tool for the service robot development.

본 연구는 서비스 로봇 개발을 추진하기 이전 기획단계에서 개발 비용에 영향을 미치는 항목을 도출하고, 각 항목별 영향력의 크기와 우선순위를 도출하기 위한 연구이다. 특히 서비스 로봇은 적용 환경과 수행해야 할 임무에 따라 요구되는 기능, 부품이 달라지고 이에 따른 가격이 천차만별일 뿐만 아니라 소량생산이 대부분으로 비용 추정의 중요성이 강조된다. 이에 따라, 본 연구에서는 서비스 로봇 개발 및 기능을 추가하는 과정에서 특정 임무를 위해 추가되는 각종 센서, 매니퓰레이터, 통신모듈 등 개별적으로 비용에 영향을 미치는 요소를 기능 항목으로, 운용되는 환경이나 개발과정에서 충족해야 하는 방진, 방수, 내구성 테스트 등 개발 비용에 전체적으로 영향을 미치는 요소를 조정 항목으로 구분하고, 각 항목별 세부 기준을 도출하기 위한 FGI를 수행하였다. 또한 각 항목별 비용 가중치 결정을 위하여 국내 전문가 84명을 대상으로 델파이 조사를 시행하였다. 분석 결과, 기능 항목 6개(세부 기준 41개), 조정 항목 5개(세부 기준 17개)가 도출되었으며, 각 항목별로 비용 가중치와 순위를 제시하였다. 본 연구를 통해 서비스 로봇 개발 기획단계에서 개발비용을 추정하고, 기능을 선택할 수 있는 의사결정 요소로 활용 할 수 있다면, 기업이 서비스 로봇 개발의 전략적 도구로 활용할 수 있을 것이며 이를 통한 시장 진입과 확장에 도움이 될 것으로 예상된다.
