Tee it up How to put a Golf Ball on a Tee David Wilkerson, Eric Brunt, Ty Kuehl, Dave Peters, James Etzkorn

Outline We decided that our objective was to put a golf ball on a tee. We brainstormed several prototype designs. Our final design incorporated 5 modules working together to put a golf ball on a tee. Our design worked fairly well, only requiring intervention once.

Introduction The problem that we faced was how to put a golf ball on a tee. Limitations included materials and time. Our goal was to build a complex machine to perform the simple task of putting a golf ball on a tee.

Design Alternatives Each module had different design alternatives Pulley Tilting Ramp Rotating wheel CO 2 elevator Powered Wheel

Prototype Design All the modules were built independently and final adjustments were added when the modules were joined

Pulley Pulley Activation Hopper Drive Golf ball conveyance

Tilting Ramp Weight Distribution Stopper Automatic reset

Rotating Wheel Counterweight Catcher Automatic Reset Touch Sensor

CO 2 Elevator Trigger method Balloon Containment Chemical reaction Containment of reaction Initiating reaction

Powered Wheel Touch Sensor Balance Friction Stabilizing Tee Modifications Timing

Prototype Performance 1 st trial: multiple failures 2 nd trial: one unprecedented failure

Conclusion Design obstacles overcome Prototype testing Prototype performance Successful machine Improvements
