2. INDEX 1. ANSWER TO THE LAST QUESTION 2.HOW TO BEND 3.DESIGN 4.FURTHER PLAN 5.Q & A

3. 1. ANSWER TO THE LAST QUESTION 1.Bent wire angle verification Using optical microscope (Provided by the Company to proceed with the project)

4. 2. HOW TO BEND 2.1 Design bending part - Concentrating on bending part

5. 2. HOW TO BEND 2.2 Consideration Force Simplicity (Directly related to the price) Accuracy

6. 2. HOW TO BEND 2.3 Bending motor Spec 5 phases, 0.072deg/phase 3.64V, 1.4A 20N*m holding torque 1:10 gear ratio Sufficient force to bend ※ Wire is bent easily even by hand Step motor

7. 2. HOW TO BEND 2.4 Concepts Using hole Using clamp Using pin

8. 2. HOW TO BEND 2.5 Final concept Bending part Using Pin Necessity of Guide Part which is enabling bi-directional rotation The Guide must be close to Bending part ※ More Details to consider - Simple - Precision - Recommendation of Professor

9. 3. DESIGN Guides Pins Engaging part of the Pin and the Motor Wire Motor

10. 3. DESIGN Installing the two Guides in order to allow for bi- directional rotation

11. 4. FURTHER PLAN  Doing an Experiments and Supplement  Work on Programing for bending motor

12. 5. Q & A
