Phase 2: Concept Development
In phase 2 I compiled the information I obtained in phase 1 and came up with goals to shoot for with my design. Here are the goals that I came up with in no particular order:
1. Firm grip
2. Narrow well-mating tip
3. Efficient linkage
4. Multiple prehension patterns

9. Lightweight
10. Cosmetic appearance
11. Ability to grasp fragile objects
12. Tunable to the user
