Auto - Drive An Automated Driving Range

Team Members Mike Loiselle Jared Beland Jeremy Paradee

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

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.
