Analysis and Research

Left leg follows right to "anchor"

 

Observations:
      I watched Britt rock climb to learn how he climbs with his current prosthetic leg and imagine how a replacement leg could make rock climbing easier.
     Without an active knee, he cannot initiate maneuvers with his left leg. Instead, he pulls himself up on a toe hold with his right leg and then uses his prosthetic leg to anchor himself there. Most often, he simply uses his prothetic leg for balance.

Research:
     Because I had no prior experience with prosthetics, much of the time I spent on this project involved research. I received assistance from experts in prosthetics, engineering, manufacturing, and amputee athletics. Acquiring suitable parts and materials for this project also required substantial research.
     I concluded that the ideal rock climbing leg would be strong, lightweight, and stiff. The foot should be able to grip rocks from multiple angles and should not require a lot of force to use, since Britt only has limited strength in his stump.
