EE/CS 480 Fall October, 2007 University of Portland School of Engineering Overview Introduction Scorecard Plans Issues/Concerns Conclusions

EE/CS 480 Fall October, 2007 University of Portland School of Engineering Introduction Our Robotic Arm: Replicates normal human dexterity and range of motion Proof-of-concept for prosthetic application as well as test-bed for a mobile robotic arm To create a cost effective and cost conscious arm, that will allow it to be easily affordable in future applications.

EE/CS 480 Fall October, 2007 University of Portland School of Engineering Scorecard Previous month’s plans: –Complete internal forearm frame design Wrist joint design “Bone” structure and internal cavity Rotation of wrist –Complete project plan draft What we did: –Drafted Project Plan Schedule and tasks with interdependencies –Discussed internal cavity design of forearm –Defined details for arm design, and narrowed down final details to two options to decide between

EE/CS 480 Fall October, 2007 University of Portland School of Engineering Plans Solidify and finalize arm design –Wrist and elbow joint movement, and connection points –Finalize choice of bone structure –Complete preliminary CAD models If time permits look at motion Start on ME Final Report Work on Design Review
