Project Lost Intelligent Leg Prosthesis Team Eric Iversen Kathryn Lowe Eric Paugh (Lead Egr.) Advisor Dr. Lillevik (EE) Dr. Chamberlain (ME) Industry Representative Jonathan Fant Future Robotics Company November, 2005 University of Portland School of Engineering

Overview Introduction Accomplishments Unfinished Business Plans Issues/Concerns Conclusions November, 2005 University of Portland School of Engineering

Introduction Transfemoral (Above-Knee/AK) prosthesis solutions: Single axis/polycentric Friction lock Hydraulic/pneumatic Computerized The pneumatic control valve only adjusts when the user’s pace changes Project goal: To reduce fatigue by simulating a normal gait Final product functions as replacement knee, lower leg, and foot November, 2005 University of Portland School of Engineering

Accomplishments Completed EE FS and Plan documents Completed ME written project update Modeling/analysis of the knee and foot design November, 2005 University of Portland School of Engineering

Unfinished Business Motion Capture Lab Build test mockup of leg Possible field trip to Seattle Systems in Poulsbo, WA (Seattle Power Knee) November, 2005 University of Portland School of Engineering

Plans Work over break Complete Test Device 1 Complete ME Modeling/Analysis Complete EE Schematics and AC/DC Analysis November, 2005 University of Portland School of Engineering
