2. Description  Coaches and athletes in the Genesee Region of Special Olympics New York are interested in adding bocce to the selection of sports  Many athletes lack the strength and/or mobility to be able to throw or roll the balls used for bocce.  The customer envisions a product that will be adaptable for athletes who have the use of at least one hand and can grip a ball.  Resulting device will make the game of bocce accessible to athletes who normally do not get to participate in the Special Olympics.

3. Bocce Ball

4. High Level Customer Needs  Assist in rolling pallina and bocce balls  Maintain skill of game  Low transfer/setup time  High portability  Simple

5. S.O. Approved Bowling Ramp

6. Engineering Specifications  Velocity ≥ 2.77 m/s  Weight <102 Lbs  Setup Time < 3 mins  Transfer Time < 2 mins  Accuracy/Precision Within one ball distance  Safety >2.77 m/s

7. Concept Summary  V-Channel Ramp Potential energy Placement on ramp determines distance  Swivel Base Allows aiming in a 15° bi direction arc Supports Profile  Damper System Restricts repeatability  Protective Case

8. Concept

9. Concept Side View

10. Unique Damper Subsystem

11. System Architecture

12. High Risk Assessment Risks  Distance the pallina travels (wet/dry court)  Sensitivity: Ball placement on the ramp  Manufacturing Composite Material  Critical Item: Unique Damper System Mitigation  Design for highest coefficient and farthest distance  Sensitivity: Analysis done in simulation and physical setup  Old concept: Use V- shaped aluminum w/ same profile  Use simple lock/unlock system

13. Current State of Design  Design meets all customer needs  Design meets engineering specifications. Full scale testing needed to verify.  On target to come in under $1500 budget with a total build cost of $620.  MSD 1 Schedule: Currently on schedule.  MSD 2 Schedule: Completed for 11 Weeks  Confident in overcoming actual friction on bocce court.

14. Milestone Schedule for MSDII  Week 2 Composite Mold Finished  Week 4 Composite ramp proven Subsystem completed  Week 6 Prototype built  Week 8 Proven System w/ documentation
