Hi Pierre, Thanks for this link. QSpider seems to be an application dedicated to robotics. By 'application', I mean a kernel + a GUI. The Ubiforge project (http://www.urbiforge.com/) recently released under a free license a set of software components dedicated to robots control. Don't know if these projects both use a standardized API or data model, but I don't think so. I uploaded a couple of months ago a DYN package to the pythonocc svn repository. It aims at providing rigid bodies simulation features and relies on pyODE, maybe not the most efficient library but the one I have a few experience with (see http://www.youtube.com/watch?v=IW5VYbCGFYc and http://www.youtube.com/watch?v=_UVXC3X-dvU). This work is not finished yet. According to me, the most promising library is YADE ( https://yade-dem.org/wiki/Yade), which I've been following for a long time. I always wanted to get deeper in Yade but never found time to do it. Best Regards, Thomas
