Project Objectives

• Problem Statement Design and construct a system
  that can collect golf balls.
• Constraints
• Must function on variety of different terrains
• Greater efficiency than current systems on the
  market
• Must be relatively inexpensive
• Must vary from similar products currently
  available
• Fast in operation (400 square feet per minute)

4
Preliminary Information

• Information about PGA standard golf balls
• Weight 1.600-1.620 ounces
• Diameter 1.660-1.680 inches
• Components of PGA golf balls
• Core Polybutadiene or a proprietary liquid
• Middle layer Ionomer or rubber string
• Cover Urethane elastomer, polymer alloy

5
Justification for Design

• Courses employ maintenance crew to collect golf
  balls off rough terrain
• Typically 7-10 employees
• 6.50 per hour for each employee
• Removing need for manual pickers would save
  estimated
• 37,500 - 62,400 per year

6
Justification for Design

• Issues with Current Collection Systems
• Can only operate on flat terrain
• Slow (5-10 mph)
• Expensive ( gt1500)
• Inefficient

7
Current Collection System

• Rolling Pin Method
• Comprised of bristled roller, attached to back of
  collection unit
• Golf balls are lodged into the bristles
• Stationary ledge removes golf balls from bristles

8
Current Collection System

• Advantages
• Capable of collecting golf balls over a large
  area
• High accuracy in collection on flat surfaces
• Collects a large number of golf balls during a
  single run

9
Current Collection System

• Disadvantages

• Slow speed, typically 5-10 miles per hour
• Can damage the land when used on golf courses
• Inability to cover rough terrain
• Expensive, typically 1500 per unit

10
Important Considerations for Design

• Weight
• Damage terrain
• Slows operation of system
• Size
• Difficulty in storage
• Susceptible to tipping over
• Cost
• Inexpensive (lt500)
• Efficiency Accuracy
• Lowers cost of maintenance
• More desirable product for end user

11
Final Product

• Components
• Automotive Base Unit
• Gathering System
• Collection System

18
Fully Assembled Final Product

19
Performance Measures

• Tested Collector on 4 types of terrain
• Flat surface with thick grass
• Flat surface with patchy grass
• Flat surface with no grass
• Uneven terrain
• 3 test runs per surface
• 120 golf balls per test run

  golf balls
• Following Constraints were met
• Functions on variety of different terrains
• Greater efficiency than current systems on the
  market
• Relatively inexpensive (lt500)
• Fast in operation
