Haiyang Liu · Luoyang Shifan Xueyuan xuebao · 2009
An automatic table tennis ball server is designed by using infra-red sensor and a few electric devices.This type of server will meet the ball-players' continuous needs of balls.Once the container are out of balls,the motor that provides balls stops,at the same time the alarm is automatically turned on to alert the staff to add more balls into the balls container;when the ball container has been filled with appropriate amount of balls,the device will restore its automatic function of serving balls to the players.By using this device,it is unnecessary to arrange a person to serve the balls;the efficiency of training is improved as well.In addition,the device automatically records and counts the ball serving.This can provide a basis for the coaches to decide on the next step in the training program.Therefore,the automatic ball provider has a hopeful future in its application.
