Background technique

Table tennis is our national sport in China, and it is very popular in national sports, but athletes' impressive results in the competition are inseparable from their usual training. In training, athletes basically rely on two people to practice against each other. However, if the strengths of the two parties are different, athletes with good skills may not be able to achieve the training effect they want, and the training time needs to be arranged by two people, and there is no freedom in time, so the training cost is very high.

The existing table tennis ball throws the table tennis ball through the two rotating wheels inside the ball ball, and changes the flight speed of the table tennis ball by changing the speed of the two rotating wheels. Change the rotation direction and rotation speed of the table tennis ball by changing the speed difference between the two rotating wheels. The speed of the upper friction wheel is higher than the speed of the lower friction wheel, and the topspin ball is thrown. Otherwise, throw the backspin ball.

The technical action of table tennis is a special skill that contains multiple elements, and the skill can only operate normally in actual use when the elements are complete.

For example: the elements that determine the player's return to the ball are composed of

1. Predict the speed of the table tennis ball based on the hitting speed of the opponent's racket.

2. Predict the horizontal angle relationship between the racket and the table tennis ball when the opponent hits the ball to predict the incoming direction of the table tennis ball.

3. Judging the rotation direction and rotation speed of the table tennis ball according to the vertical friction angle and speed relationship between the racket and the table tennis ball when the opponent hits the ball.

However, the existing table tennis ball does not have any information indicating the flight speed, rotation speed, rotation direction, and rotation speed of the table tennis ball. Actions. This default leads to serious incompleteness in the skills trained by the existing table tennis service department. This incompleteness determines that the technical movements trained by the existing table tennis service department cannot be used in practice and must be corrected. This kind of flawed skill that has been formed requires more training resources for individual training. Therefore, the existing table tennis ball does not have the function of improving the technical level of table tennis because of its serious inherent defects.
