The World Cup in Qatar uses soccer balls that their company Adidas calls the fastest, most accurate and technologically advanced in history, according to the Daily Mail. https://www.dailymail.co.uk/sport/football/article-11483753/Bizarre-photo-reveals-high-tech-World-Cup-footballs-need-charged-used-games.html These balls are not enough to inflate - they need to be charged. This can be seen in the photos posted on Reddit, where several balls are connected to the charger, like smartphones.
The balls are called "Al-Rihla", which means "journey" in Arabic. Inside the camera there is a miniature sensor weighing 14 grams, which measures indicators such as speed and direction of movement, and allows you to track offside if necessary. The sensor provides real-time ball tracking because it is connected to cameras located throughout the field. “Every time the ball is kicked or headed, thrown into the air, or just touches the lawn, the system captures it at 500 frames per second”, - says Maximillian Schmidt, managing director of sensor company KINEXON, who made the sensor.
The sensor is powered by a small battery that Adidas says can last up to six hours of active use and up to 18 days when the ball is at rest. When the ball goes out of bounds and another ball is put into play, the KINEXON server automatically switches to inputting the new ball.
Adidas developers also claim that the new balls are faster than any other, as the improved design allows them to maintain significantly higher speeds when moving through the air. The extra speed comes from the fact that the ball is made using water-based paints and adhesives. The speed of the ball was confirmed by Uruguay goalkeeper Sergio Roche, who said that it greatly complicates his work: “Year after year it becomes more convenient for attackers to play, but for us it is harder... It is a very fast ball”.
