Hard Surface Leg-Robotic Prosthesis

Hello Guys, I started this project to study hard surface modeling, but I found an amazing robotic prosthesis leg, so I decided to modeling it , I learned a lot doing this, a lot of fun. This prosthesis is a project by Dr. Xiangrong Shen from U.A (University of Alabama) if you wanna read more about that, links bellow. I hope you like, C&C are welcome. http://uanews.ua.edu/2014/05/ua-engineering-professor-awarded-nsf-career-award-for-robotic-prosthesis/ http://www.sciencedaily.com/releases/2012/11/121108131416.htm
