DMU Kinematics10 Revolute Joint1 Rigid Joint / 1 leg
Gazelle 을움직이기위해판 2개를추가로만들어주었다.큰판-작은판 (Prismatic Joint)
DMU Kinematics
Mechanism 1 : 오른쪽뒷다리움직임제어
Mechanism 2 : 왼쪽뒷다리움직임제어
Mechanism 3 : 왼쪽앞다리움직임제어
Mechanism 4 : 오른쪽앞다리움직임제어
Mechanism 5 : 발판을움직여가젤이달리는것처럼보이게하는효과
DMU KinematicsSequence 1 : Simulation들을합쳐동시에움직일수있게함 (Duration = 10)
Simulation Video
Limits1. 치타의움직임과가젤의움직임을함께구현하려고하였으나, 파일명이겹치는문제등이발생하여불가피하게치타는 Modeling 에서만족해야했다.
2. 처음계획할때에는, 기어(gear joint), 피스톤등을이용하여허리의움직임을구현하고, 목부분의움직임도구현하려고했으나, 구현하지못하였다.
3. 치타의머리와몸통부분, 가젤의머리와몸통부분, 그리고각각의다리와발이라는세파트로나누어작업을진행하였다. 외부에서도면을전혀얻을수없었을뿐더러, 서로공통적인치수를맞추지않아 Assembly design 에서 affinity 기능을이용할수밖에없었다.
