  1. An Automated Driving Range Auto - Drive

  2. Team Members • Mike Loiselle • Jared Beland • Jeremy Paradee

  3. Background • A typical driving range consists of a range mat and a rubber tee. • The golfer pays for a bucket of balls from an attendant at the front desk. • The golfer will manually tee up each golf ball on the rubber tee and hit them.

  4. Problem Statement To design and build an automated driving range that will improve the ranges’ overall productivity and user friendliness.

  5. Problem Solution • Bill acceptor to give a signal to start the program • Network of piping to hold and transfer balls to lifting system. • Stepper motor, lead screw linear actuator, and tee to lift up golf balls. • Light / Dark Sensor to determine when ball is present on tee. • Sensors to start the timer and stop the timer for the swing speed calculator. • 7 segment displays to inform golfer how many balls have been hit and how fast each swing was.

  6. System Overview

  7. Electrical • Stepper Motor Driver • Dollar Bill Acceptor • 7-Segment Display Driver • Ball Presence Sensor • Swing Speed Calculator

  8. Dollar Bill Acceptor / Validator • Only accepts $1 bills • Less expensive (no bill changer required) • 120VAC supply voltage

  12. Ball Count Display

  13. Swing Speed Calculator (SSC) • Requires two sensors • Diffuse Reflective Sensors • One sensor to starts timer in the HC08 • Second sensor interrupts the timer

  14. Swing Speed Calculator • Use the Timer Interface Module (TIM) on HC08 • Use External Interrupt (IRQ) as input to capture sensor #1 • Use Keyboard Interrupt Module (KBI) as input to capture for sensor #1 • Configure IRQ & KBI to capture on rising edges

  15. Programming & Software • System Flow Chart • Ball Count Display Program • Lifting Mechanism Program
