Specialists from Tsukuba University built and tested a robotic training complex for volleyball players
The device consists of three pairs of robotic manipulators that move from side to side under the grid. The device performs the functions of blocking players, writes New Scientist.
The system is equipped with three players who can move at speeds up to 3.7 meters per second. The system has already been tested in training by members of the Japanese women’s team. Six players trained with the robot for eight days, while some noted that such a training is different in sensations from a real game.
Interestingly, the device can imitate the playing styles of future rivals. Continue reading
Finger injury in volleyball Volleyball players injure fingers quite often. Most often this happens when the block is executed, when the ball hits the set finger. This can happen even with professionals. Novice athletes injure their fingers even with a simple pass or ball. Finger injuries are primarily sprains, fractures and dislocations of the fingers.

Volleyball is a team sport in which two teams compete on the court, separated by a net, while striving to direct the ball so that it is on the opponent’s court, or so that the player of the defending team makes a mistake.
