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.

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.
