Simulation step

Step1：Import your file to V-rep ( File -> Import -> Mesh ,and choose you file to impot )

Step2：Choose your file ( Click right mouse button -> Edit -> Divide selected shapes,and the selceted shapes will be divided )

Step3：Name each parts ( The picture is an example )

Step4：Add the joints in the shapes ( Click right mouse button -> Add -> Joint -> Revolute ) , and copy the joint to align the corresponding position

Step5：Step by step to put each joint and part to the base ( One part connects to one joint , and there are two joints in the part C that there are two links to drive )

Step6：Add Dummy in the shapes ( Add -> Dummy ,and set properties (Two Dummies are a group ) )

Step7：Step by step to put Dummy to the shapes ( One part connects one joint , and the Dummy one side connects the part , the other side connects the joint )

Step8：All parts have to be dynamic 

Step9：This setting to the Drive shaft ( In my file is C )

Step10：Simulate the shapes
