Why automate the process?
Reducing the time spent in between shots could
increase revenues for the driving range.
Makes the game more accessible to the disabled,
elderly people, and obese.

Quantitative Requirements
Maximum 30 second ball replacement cycle time. A
cycle is from the moment the system detects a
balls absence until the system is ready for the
player to hit the next golf ball.
Places golf ball on the tee 95 of the ball
placement attempts.
Detects the presence of the golf ball on the tee
95 of the time.
