Abstract

A sensor based tennis serve training apparatus includes a stand, a ball tosser coupled to said stand, an optical marker coupled to said stand and in electronic communications with said ball tosser, the optical marker to mark a ball strike zone, an ultrasonic tennis arm movement detector attached to said stand and in electronic communication with said ball tosser to detect arm movement, and a selectively timed ball discharging magazine attached to said stand and in electronic communication with said ball tosser. Said apparatus can further include an electronic communication control box coupled to said stand and mediating electronic communication between said magazine, ball tosser, ultrasonic tennis arm movement detector, and optical marker.
