3. EE/CS 480 Fall 2007 3September, 2007 University of Portland School of Engineering Introduction Our Robotic Arm: Replicates normal human dexterity and range of motion Proof-of-concept for prosthetics as well as test-bed for mobile robotics DARPA research study is already looking into advanced prosthetic arms, BUT: –Budget is $30.4 million Can it be done inexpensively?

10. EE/CS 480 Fall 2007 10September, 2007 University of Portland School of Engineering Concerns/Issues Concerns/issues: –Servo space requirements –Feasibility of testing/simulating carbon fiber “bones” Possible solutions: –CAD modeling of forearm for proportion –Open ended – depends on material choice

11. EE/CS 480 Fall 2007 11September, 2007 University of Portland School of Engineering Conclusions Our priority: designing a highly dexterous robotic arm (without spending $30.4 million) Potentially a multi-generational project – other teams may develop further
