Background 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.

Objective

1) Create a device that can be used for training local athletes to compete in Special Olympics bocce.

2) Device should maintain skill level of game

3) Design for mass manufacturing.

Design Overview

Velocity- Ramp, speed controlled height of ball placement

Aiming- Swivel base, handles, auto correction after each turn, locking mechanisms (damper)

Portability- Light weight, collapsing, wheels, cover

Issues From Concept Review

Instead of hinges, some sort of pins that would slide through legs and some sort of mount located underneath the ramp. Incorporated into final design

Obtain some info on wheelchairs, percentiles etc. This will be considered when determining the height of the ramp. Research ANSUR database, verified ramp height would be feasible.

Make sure balls are rolling not sliding down the ramp. Feasibility analysis.

Have it drop into some sort of trough for transportation. Design cover.

Position of screws, adhesives etc. Will be shown on drawing. Composites professor is Dr. Ghoneim. Hand off for manufactures? Mold specs and detail procedure. Use gutters for experimentation. See of steel angle bar.

Supporting CalculationsFinal velocity required to go 18.3 m:

Height required to gain enough velocity to go 18.3 m:

Feasibility analysis to determine if slipping down the ramp occurs:

The ball will roll without slipping if the tangential force, ft , is less than the force due to static friction, fs.

:

:

Solving for the tangential force shows that some slipping does occur. The only way to mitigate this sliding motion is by utilizing a ramp profile with a maximum angle of 30°. Unfortunately this shallow an angle would not allow for sufficient momentum for the ball to go the required 18.3 m.

Risks Identified/Mitigation Pallina not traveling far enough

Designing for the worst care scenario Highest coefficient of friction Farthest distance necessary (60ft)

Time constraints in manufacturing the ramp (composite material) Contacted composites professor and lab manager and will be

starting as soon as possible (Prototype worst case- Aluminum) Vulnerability to tilting from side to side

Robust hinges/pins, maximum distance between legs Placement of top cover during time of the game

Alternate methods discussed- will be revisited if need be or leave cover in van

Damper system Allow excess time in schedule

Page 20: Adaptable Bocce Ball Launcher Detailed Design Review Angela Marcuccilli -ME Brad Johnson -ME Bryan Fleury -ME David Ferguson –ISE Yash Singh -ME.

Risks Identified/Mitigation Cont. Portability lifting in out of van

Add handles/recessions in base Swiveling around when packed up

Straight pin through turntable to eliminate rotation Ball slipping on the ramp rather than rolling

Used slipping as a constraint for angle of the ramp Energy loss due to initial drop

Keep the end lift as parallel to the ground as possible, gradual bend in ramp and factoring energy loss into equations

Handle that’s able to be used by an athlete (little grip) Using pulleys to reduce gripping force
