INTERACTIVE DYNAMIC SIMULATOR FOR MULTIBODY SYSTEMS [PDF]
International Journal of Humanoid Robotics, 2012 We propose an interactive dynamic simulator for humanoid robots using constraint-based methods for computing interaction forces with friction. This simulator is a part of a general framework for prototyping called AMELIF and is a successful integration of physical models.
