Thank you for your kindly reply. And I'm just amazed that I'm also trying to develop the way to create dynamics equations by Kane's method! I have to look into pydy and thanks a lot for your providing such a great information again! P.S. By the way, my codes to create the equations have ever provided Euler's equations for rigid body dynamics, the equations for double pendulum, those for passive walking, and on and on and on... -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
