Alan, I've browsed this text a little, but to be honest, I was unable to see the direct advantage of such an approach, at least for the type of work I'm involved with. I'm willing to trust that the mathematics are cleaner and more complete, but I'm curious what the advantage is in the end. Do

Hi, 2009/5/29 2006.uchida 2006.uch...@gmail.com: Thank you for your response. I first knew Autolev. I took a look at one of the sample test codes of Pydy named simplependulum.py and didn't look into the details but it appears that it allows us to obtain motion equations and simulations by

This is cool, it is good to see other people who are familiar with Kane's method, there aren't many of us :) Are you familiar with Autolev? With PyDy, I am working to achieve some of the same behavior as Autolev, but make it even better, and have a lot more features. I'd love to hear your
