A coworker of mine sent this to me today. (Thanks Johnnie!)  This is one of the coolest looking Robotics projects I have seen to date.  Check out the Boston Dynamics site to find out about BigDog.  The video is definitely a must see.  I wonder if BigDog was designed in SolidWorks?  A little Google searching yields some evidence to suggest it could have.  Enjoy and have a GREAT weekend!
