Two devices from Russia with tennis balls. 1. The world's first plywood tennis robot. (I think so.) Android, IR control, two step motors, servo, replacement head for 2 or 3 brushless motors, car battery. Requires completion but the 3D printer is determined to kill him. 2. Room game-simulator which needs only 1.5 sq. m. free. Working model. I use it for long Russian winters in a country house. Proved too hard for children,although intended as a children's game. |

Feeding frequency 130 balls per minute. It beats all the other robots on market. I feel so proud of Russia. Yes.  https://youtu.be/bRwu-5833w8?t=186 |

Are you able to serve 130 balls per minute? By the way, http://www.tennirobo.com has 120 balls per minute feeding speed, but it is just limited to this value in software, and can be increased up to 150 balls per minute But I don't think it's necessary... |

Я смотрел ваши демо-ролики и вижу как ваша пушка стреляет одиночными залпами. Поэтому я имею подозрения что быстрые серии она выстреливать неспособна и для активной тренировки негодитса. Если я ошибаюсь, покажите мне видео с какой реальной скоростью умеет стрелять ваша пушка. И я не вижу сколько мячей вместительность в бункере. Спасибо.. |

Пушка должна обеспечить интенсивную тренировочную нагрузку. Смотрим реальную тренировку, для развития скоростной выносливости, южнокорейские школьники. Тренер кидает мячи в темпе 90 в минуту, серия 30 мячей. Пушка должна обеспечить соответствующую скорострельность и вместительность бункера 30-40 мячей. На демо ролике из Питера, теннисный робот "Фора Автомат" кидает мячи 90 в минуту. Робот имеет световой индикатор вращения на фасаде. |

We are talking about if the TenniRobo really able to feed balls with high speed frequency? Igorponger has doubts about it, and if the TenniRobo good for training process? He asked me to make video with 90-120 balls/minute series. As example, he showed video from South Korea - 30 balls for one boy with 90 balls/minute frequency. Ok, I think it's correct question, and I have to make this video. But now I am in countryside and I have no table here (unfortunatelly). I'll do it probably on next week. For now, please look this video at 2:50 time position https://youtu.be/r_E93Cn9mCc It is the old version of robot, but it has the same feeding mechanism, as the TenniRobo now. On this video feeding frequency is about 90-95 balls/minute Now TenniRobo has tank for 100 balls |

Two or three aircraft engine used in the work to produce the noise of an airplane taking off. Plus the resonance from the plywood body. The room sounds awful. But my tennis table stands in the open outdoor pavilion, and there the noise is not audible. However, in single shots the motors are switched off after a few seconds. Rate of fire is unlikely to be higher than 30-40 shots per minute. In the pipe under the tub only 3 balls. There are problems with the height of the bottom. But it's better than shooting one minute and five minutes, then pick up the balls. This is totally unacceptable. And I refused it at once. There are hundreds of such robots. What's the point of inventing another one like this? |
