Solid-State Prosthetic Arm A Multidisciplinary capstone senior design project with the cooperation of mechanical (MAE) and electrical (ECE) engineering Departments MAE 435: Status Update 2 2014 - 2015 Team: Michael DiGiacomo Peter Dinga Joseph Flores Taylor Jones Shelby Nedrick (Team Leader) Denzel Stewart (ECE) Advisor: Onur Bilgen Add Departments!!! BOTH MAE and ECE Add Denzel!! – This is a multidisciplinary project.

Project Breakdown Structural Component Electronic Circuit Board Artificial Muscle Bundle DO not use “Figure X” in figure captions. (that practice is for papers only) Fix this throughout the presentation.

Structural: Design Completed Brainstorm ideas First Simple Joint Design Second Iteration Test Swatches Completed Brainstorm ideas Draw possible designs using Inventor (Autodesk- San Rafael, California) Perform Stress Analysis Print out joints Evaluate designs Reiteration Third Iteration Joint Design

Artificial Muscle: Muscle Bundle Ring Terminal End Cap Layout Wire Groove Cap Epoxy Silicone

Controls: Proposed Integration Controls and Artificial Muscle Incorporate C-DAQ with circuit Compact Data Acquisition System Allowing for PC control Operating circuit and collecting data Battery PC Battery Circuit SMA Structure USB CDAQ Circuit SMA Structure Integration and Manual Control Integration and Digital Control
