What is the function of the little red remote control car at the World Athletics Championships?

The little red car is remotely controlled by courtside staff and can transport javelins and hammer throws. When transporting the javelin, there is a device on the top of the car similar to the luggage storage device on the roof of a tourist car, which can hold the javelin. When transporting hammers, the body is hollow and the hammers can be put into the body. This is also done to not interfere with the athletes' competition and to make it more convenient and faster.

This car can run as fast as 100km/h, but it does not need to go that fast in the competition, probably no more than 30km/h. During the competition, the hammer throw players made preparations, and with a loud roar, the hammer throw was thrown in a circle.

Immediately afterwards, the long-throw return car also ran out like an arrow, and soon arrived at the landing point of the hammer. The referee team placed the hammer on the car, and then the car again He quickly returned to the controller.

As early as the 2008 Beijing Olympics, this long-throw return vehicle was already in use. It is fast, stable and safe, and can prevent people from being injured when returning equipment.
