EDGE™
Product Description/Project Objective Statement
This project is in its second generation. The overall goal is to
design and build an artificial limb (arm and hand) that is capable of
all of the directions of freedom of a human hand. The first
generation accomplished design and building of the arm and the
first three fingers. The main goals for the second generation
project is to add a pinky finger and thumb. The design and
construction of the pinky finger and thumb should be accomplished
by the end of the winter quarter of the 2008 academic year.
EDGE™
Key Business Goals/Project Deliverables
The goal of the second generation air muscle artificial limb is
to add a pinky and thumb with all of the degrees of freedom of a
human hand. This design should take into consideration future
scale down, and should be implemented onto the existing project.
• Design of Pinky Finger
– Research Human Anatomy
– Determine Joint Types/Locations
– Determine muscle attachments
– Controls Design
• Design of Thumb
– Research Human Anatomy
– Determine Joint Types/Locations
– Determine muscle attachments

Key Business Goals/Project
Deliverables Continued
• Optimization
– Determine areas in need of optimization
• Enhance reliability
• Enhance ease of use (programming)
– Brainstorm solutions and alternatives
– Implement Design Solutions
– Test Design
EDGE™
Primary Market/Project Opportunities
• This project is to be designed for research being
conducted by Dr. Lamkin Kennard and a
Masters student.
• The findings in this project will be applied to a
scaled down model for use in microvascular
surgery.
EDGE™
Secondary Market/Project Opportunities
• This project could serve as a way to entice future
students into the engineering program.
• It is possible that this product could be used for
wireless surgery. Patients could have surgery
performed by a doctor thousands of miles away.
• Findings could also provide solutions for
amputees.

Phase 1: Concept Development
Identify Customer Needs - Interviews
• Primary Customer Interview
• Other Stakeholders
• Current MSD Student Interview
EDGE™
Primary Customer Interview
• Dr. Lamkin-Kennard
– I interviewed Dr. Lamkin-Kennard on March 19, 2008
• Established what needed to be completed
– Pinky finger
– Thumb
– Optimization
• The arm will later be scaled down for research in
microvascular surgery
• Large emphasis on maintaining all DOF of human
hand
EDGE™
Primary Customer Interview
(Continued)
• EE and or CE will be needed for programming
optimization
• Air muscles are controlled by air which causes the
muscles to move
• Air muscles are being used instead of servo
motors because of cost, and air muscles have the
ability to get wet.
EDGE™
Other Stakeholders
• I have met with professor Wellin about improving
some of the labview coding. He said He would
be very happy to help with the project.
EDGE™
Past Senior Design Team
• The current Senior Design team has finished the
first generation of the hand.
• I interviewed Josa Hanzlik and Ellen Cretekos on
April 3, 2008.

The team is building their own air muscles
Professor Wellin acted as a Labview Liaison
They strongly suggest rapid prototyping
The current Design Team recommended that I speak
with Dr. Doolittle about biomechanics of the hand

Needs Statements
Graphical Interpretation
Organize the Needs into a Hierarchy
Establish the Relative Importance of the
Needs
EDGE™
Needs Statement
This project must basically add a thumb and pinky finger to an existing
artificial hand. All of the directions of freedom of a human hand must be
maintained. The project also involves optimization of the past project to
make it more robust and make the controls interface easier to use.
