5. 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.

6. 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.

9. 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.

10. 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.

12. Phase 1: Concept Development Identify Customer Needs - Interviews
Primary Customer Interview
Other Stakeholders
Current MSD Student Interview

13. 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

14. 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.

15. 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.

16. 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

17. Phase 1: Concept Development Identify Customer Needs - Interpret
Needs Statements
Graphical Interpretation
Organize the Needs into a Hierarchy
Establish the Relative Importance of the Needs

18. 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.
