Abstract

In this paper, we propose a new parallel mechanism for the legs of biped robots and the control of the robot's locomotion. A leg consists of two 3-DOF parallel platforms linked serially: one is an orientation platform for a thigh and the other is the 3-DOF asymmetric parallel platform for the shank. The desired locomotion trajectory is generated on the basis of the Gravity-Compensated Inverted Pendulum Mode (GCIPM) in the sagittal direction and the Linear Inverted Pendulum Mode (LIPM) in the lateral direction, respectively. In order to simulate the ground reaction force, a 6-DOF elastic pad model is used underneath each of the soles. The performance and effectiveness of the proposed parallel mechanism and locomotion control are shown by the results of computer simulations of a 12-DOF parallel biped robot using $SimMechanics^{(R)}$.

본 논문은 2족 보행로봇을 위한 새로운 병렬메카니즘을 제안하고 있다. 각 다리는 3자유도를 갖는 병렬 플랫폼 2개가 시리얼로 연결되어 있는데, 허벅지와 정갱이 역할을 한다. 이 제안된 로봇을 위한 보행 궤적은 보행평면상에서는 중력보상역진자모드를 사용하여 구하였고, 횡방향으로는 역진자모드를 사용하여 구하였다. 지면으로부터의 반발력을 시뮬레이션하기 위해 발바닥 밑에 6자유도의 패드를 사용하였다. 제안된 메카니즘과 보행제어의 효율성은 SimMechanics를 이용한 12자유도 병렬 2족보행로봇의 시뮬레이션을 통해 입증하였다.
