Abstract

As research on the practical use of robots has continued since the past, advancements into each field of society are being continuously tried in modern society, breaking bounds from the previous experimental environment. However, in order for robots to be applied to the real environment, the production cost, which is considered to be the biggest disadvantage of commercializing the existing robot platform, and the adaptability issue in working environments in terms of human standards must be considered. This paper proposes a robot of biped walking form, which conforms to the degree of freedom and the size of human beings. By replacing the encoder with a combined module of potentiometer, the high cost of production is reduced, and by adopting a modular design that is easy to replace parts, the maintenance cost of robots is reduced. Finally, stability was verified by applying a walking pattern to two dummy robots of different sizes and motor arrangements. In this paper, after developing the real biped walking robots, the performance and usability were verified through walking experiments and applying the walking pattern using the developed robots.

과거부터 로봇의 실생활 활용에 관한 연구가 지속됨에 따라 현대사회에서 이전까지의 실험 환경에서 벗어나 사회 각 분야로의 진출이 지속적으로 시도 되고 있다. 하지만 로봇이 실제 환경에 적용되기 위해서 기존의 로봇 플랫폼 상용화의 가장 큰 단점으로 꼽히는 생산 비용과 인간 기준의 작업환경에서의 적응성 문제가 선결되어야 한다. 본 논문에서는 사람의 자유도와 크기를 따르는 이족보행 형태의 로봇을 제안하였으며, 엔코더를 포텐셔미터 접목모듈로 대체하여 높은 생산 단가를 절감하고, 파트 교체가 쉬운 모듈형 설계를 채택하여 로봇의 유지 보수비용을 절감 하였다. 최종적으로 크기와 모터의 배열이 다른 두 가지의 더미로봇에 보행패턴을 적용하여 안정성을 검증하였고, 본 논문에서는 제작된 실제 로봇들을 이용한 보행 패턴을 적용 및 보행 실험을 통하여 제안한 이족보행 로봇 적용가능성을 검증하였다.
