Abstract

In this paper, kinematic based walking pattern generation of biped walking robot is reviewed. Biped walking robot should be consisted of 6 Degree of Freedom(DOF) for each leg to walk properly in 3 dimensional circumstance. In this paper, simple structure of biped robot is depicted for walking pattern firstly. After fixing path of ankle of the robot, angle joints are coming from kinematic equatioins. Coordination of joints of a robot was set for dynamic analysis also. So walking pattern of a robot will be designed using dynamic equations of coordination of joint angles. Finally, setting of ankle of robot and pattern generation are key procedures of the robot walking.

본 논문에서는 기구학을 이용한 이족보행 로봇의 보행패턴 생성방법을 살펴본다. 2족 보행로봇이 3차원 공간상에서 모든 동작 및 보행이 가능하기 위해 필요한 자유도는 각 다리별로 6자유도이다. 따라서 본 논문에서는 로봇의 보행을 위해 간략화된 보행로봇의 구조를 살펴보고 발목의 경로를 설정한 후 기구학을 이용하여 조인트 각도를 파악하여 생성한다. 또한 로봇의 기구 해석을 위해 한쪽 다리의 조인트들에 대해 좌표계를 설정하였다. 조인트 각도를 역기구학을 이용하면 로봇의 보행 패턴을 생성할 수 있다. 최종적으로 발목의 궤적 설정과 이를 통한 보행 패턴 생성 과정을 살펴보기로 한다.
