Auto - Drive An Automated Driving Range

Team Members Mike Loiselle Jared Beland Jeremy Paradee

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

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.

Problem Solution Bill acceptor to determine the number of balls to dispense. Network of piping to hold and transfer balls to lifting system. Stepper motor, lead screw linear actuator, and tee to lift up golf balls. E-Field Sensors to determine when balls are present on tee up system, when the ball has been hit off the tee, and to calculate the swing speed. 7 segment displays to inform golfer how many balls remain to be hit and how fast each swing was.

Dollar Bill Acceptor / Validator Only accepts $1 bills Less expensive (no bill changer required) 12VDC, 24VDC, or 120VAC supply voltage Costs around $50 - $100 used In process of contacting local vendors to purchase used one or repair broken one.

Hopper System Network of pvc or aluminum piping Golf balls only travel in one path Decreases chances of ball jams Inexpensive (no electrical components) Holds a maximum of 500 golf balls

Swing Speed Calculator Requires two E-Field Sensors One sensor to starts timer in the HC08 Second sensor interrupts the timer Need four sensors total (two for right handed golfers & two for right handed golfers.

Swing Speed Calculator Use the Timer Interface Module (TIM) Port A shares two pins with the TIM Use PTA0/TCH0 as input capture for sensor #1 Use PTA1/TCH1 as input capture for sensor #2 Configure PTA0 & PTA1 to capture on rising edges

Swing Speed Calculator Further Research Needed Write a program for E-Field sensor and HC08 communications Use the time value stored in the TIM counter register and the distance known between the two sensors to write a program that will calculate the swing speed in mph. Write program and design circuit schematic to output the swing speed in mph to seven segment displays
