Gait Simulation using Multibody Dynamics
GaitSym is a forward dynamic modelling program. What that means is that you specify the forces and the program uses Newton's Laws to calculate the movements. It uses the Open Dynamics Engine physics library to do most of the hard work (opende.sourceforge.net) and provides a file format and display system so the user does not have to do any programming. It also provides various muscle models so that the forces can be generated directly from muscle activation levels and a number of hooks to allow it to be used with global optimisation tools such as genetic algorithms. The software is open source and is released under the GNU General Public License version 3.0 except for parts of the software that are covered by different licences (for example the OpenDE portions are covered by either Lesser GPL or a BSD license). If this license does not let you do what you want to do then please contact me and I am sure I can sort something out.
