South Korean archers dominated Tokyo 2020 winning three gold medals so far.
And along with the athletes' efforts, artificial intelligence technology has supported their training.
Korea's auto giant Hyundai Motor Group, supported the athletes by providing five cutting-edge technologies.
The first is a face recognition system.
When the athlete is pulling the bow, a machine analyzes their face checking the heartbeat.
This measurement can help them calm down and concentrate on the game.
And when the athlete shoots, the score is automatically recorded in the program.
Deep learning system is used to automatically edit the videos of the athletes' training and analyze their habits and weak points.
A shooting machine can sort out and remove poor quality arrows.
And, a three-dimensional printer makes a grip for the bow that best fits the athletes' hands.
Hyundai Motor Group and Korea Archery Association started their cooperation after the 2016 Rio Olympics, aiming to apply technologies used for future vehicles to archery training.
