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.

High Risk AssessmentRisks
Distance the pallina travels (wet/dry court)
Sensitivity: Ball placement on the ramp
ManufacturingComposite 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

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.
