"The Japanese team has very good defense and ball control ability. If our tall players can also defend better, the Chinese team will be stronger. In addition, I hope the team's blocking movement speed will also be faster." Although I won the ball, the Chinese women's volleyball coach Lang Ping pointed out the shortcomings of our team after the game.
On the evening of May 30, in the second round of the World Women's Volleyball League Hong Kong Station, the Chinese team defeated the Japanese team in three straight games 25-21, 25-19, and 25-17, winning two consecutive victories. The reason why the Chinese women's volleyball team won the game is mainly because they are well prepared and perform well with the captain , Zhu Ting and others. The Japanese women's volleyball team is definitely a team that needs attention.

As the 2020 Tokyo Olympics approach, many sports teams of the host Japan have increased their investment and tried every means to improve their strength while studying the characteristics of their main opponents. Among them, the Japanese women's volleyball team even introduced "black technology" in training.
To enhance the technology of Japan's national volleyball team, Japanese scientific researchers have specially developed high-tech training robots. On the training ground, they were able to make unpredictable blocks and defenses with their arms stretched out, moving quickly. It is understood that these pre-programmed trained robots move faster than humans.
From the training video, whenever the female volleyball team jumps high and spikes, the robot will use both arms to prepare to intercept. The device is called Block Machine. It consists of a track parallel to the ball net and three defensive robots. Its movement speed reaches 3.7 meters/second that exceeds humans. It can provide targeted training for the Japanese women's volleyball team by simulating the opponent's blocking and defense.
This robot will also automatically rise to the corresponding height according to the preset different defensive formations when the player spikes the ball. In the future, developers may also add motion sensors to allow robots to make unpredictable obstacles.
Not only that, Nakada Kumi also tried to summon men's sparring training, allowing them to imitate the world's number one attacker Zhu Ting, the Chinese women's volleyball team, so as to further adapt to her technical characteristics such as spiking and blocking.
However, as the captain of the Chinese women's volleyball team, and number one attacker in , Zhu Ting is not ruthless when facing the Japanese team and often plays super strong attacks. Taking the World League Hong Kong Station on the evening of the 30th as an example, Zhu Ting started and scored the highest 19 points in the game. In addition to offense, she also gave her teammates strong support in blocking, first pass, defense, and small ball connection. After two seasons of studying abroad to play, Zhu Ting has become fully mature, with both offense and defense, making it more difficult for her opponent to cope with.
In fact, volleyball is not the first project in Japan to apply robots to training. In 2017, Japan's Omron company (Omron) announced that it had developed a robot "Forpheus" that can continue to fight table tennis with humans. It can judge whether the opponent is a professional player or a beginner through the hitting speed and trajectory of the human opponent, and provides a variety of sparring modes from beginners to advanced players.
However, in terms of reaction and return speed, Forpheus can only meet the needs of beginners and amateurs. After watching the video of it playing against researchers, some Chinese fans pointed out that the speed of such a ball is not as good as the former head coach of the Chinese table tennis team, Liu Guoliang , which can be called a "multi-angle shift-speed human serving machine". The video of his training of Zhang Jike receiving serve has long been popular on the Internet.
