EE/CS 480 Fall September, 2007 University of Portland School of Engineering Scorecard Previous month’s plans: –Functional spec drafted –Project scope clearly defined What we did: –Acquired multiple research papers to build on what has already been done –Major functional components chosen

EE/CS 480 Fall September, 2007 University of Portland School of Engineering Additional Accomplishments Discussed future expansion and integration with future projects + = ?

EE/CS 480 Fall September, 2007 University of Portland School of Engineering Plans Complete internal forearm frame design –Wrist joint design –“Bone” structure and internal cavity –Rotation of wrist Complete project plan draft

EE/CS 480 Fall September, 2007 University of Portland School of Engineering Milestones NumberDescriptionOriginal 10/30/05 Previous 10/30/05 Present 11/20/05 1Functional Spec Approval10/05/07 2Project Plan Approval11/09/07 3Design Review completed12/07/07

EE/CS 480 Fall September, 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

EE/CS 480 Fall September, 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
