FPS Shooter Tutorial 3 Question

OK so I've been following those REALLY excellent FPS Tutorials that are in PDF format you can download but I'm having a problem when I import in the "Robot Artwork" and create my robot in scene, what hapen is, is that after I have followed the tutorial to the letter and added my two scripts, the "AI" script and the "AIAnimation" script, when I go to test it out my robot looks all messed up geometry wise like his legs are all scrunched up or something!! Anyone else have that problem and if so were you able to fix it and how, for the love of God how?? ;)

make the other models for the robot scale 1 (ex. Robot@walk, Robot@shoot etc) they are normally 0.01.

Remove the rigidbody from the robot
