6자유도 병렬형 햅틱장치를 이용한 구멍뚫기 작업의 햅틱 디스플레이 = Haptic Display of A Puncture Task with 4-legged 6 DOF Parallel Haptic Device

다국어 초록 (Multilingual Abstract)

A haptic rendering system is proposed for a puncture task of a virtual vertebra model. To build a mesh model from medical images, Delaunay triangulation is applied and physical models are based on elasticity theory. Also, a redundant actuated 6 DOF parallel type haptic device is designed to display large force and to resolve the singularity problem of parallel type mechanisms. Haptic feeling of puncture task and the performance of the proposed haptic device are tested by two puncture task experiments.

국문 초록 (Abstract)

본 논문에서는 가상 구멍뚫기 작업의 표현을 위한 햅틱 렌더링 시스템을 제안하였다. 가상 모델을 만들기 위하여 영상 처리 기법과 Delaunay 삼각형을 이용하였고, 실시간 어플리케이션에 적용하기 위해 간단하면서도 효율적인 후크의 법칙을 이용하여 힘을 생성하였다. 또한, 직렬형 메커니즘으로 표현하기 어려운 큰 힘을 표현하면서, 병렬형 메커니즘의 특이점 문제를 함께 해결하기 위하여 여유구동 6자유도 병렬형 메커니즘을 햅틱장치로 제안하였고 두 종류의 구멍뚫기 실험을 통하여 큰 힘을 표현할 수 있는 능력을 검증하였다.
