I built this model in June 2007 after seeing videos of Theo Jansen's amazing "strandbeest" creations. To help the design process, given the limited parts I had available, I wrote a Java program to simulate different components. You can see a couple of videos of the walker, and play with the simulation Java applet at: http://www.RoboticsLearning.com/jansenwalker and http://www.youtube.com/watch?v=qLW-NPnqbJQ Steve Putz steve@RoboticsLearning.com
