I started making a robot according to the RDV scheme. I bought all the electronics in my city, spent about $ 90. On Aliexpress, everything is the same about $ 60, but delivery is 30 days. Now the budget is about $130. Checked everything. The program works, all components work, when the IR sensor...

I decided not to buy Amicus Prime, thanks to 7sagittarius7 for the video. I will assemble a robot like RDV. I downloaded a program, an electrical circuit and 3D models for printing on his channel. Its functionality is higher, and the cost is about $100. The robot can create very strong rotations...

Thank you very much for this video. I watched it several times. It, as we say, “dots all the i”. My analysis: standing on the side of the table, you turn on the robot. You can hear the motors running. You get up in the playing area, during this time the motors picked up speed. The first topspin...

I occasionally go to the rdv channel. He improves the program. Now he has a customizable departure delay for each ball. When the robot is standing 2 or 3 meters from the table at the topspin, the flight speed is higher than that of the ball with the bottom rotation, they arrive at the table...

I continue to study robots. I'm starting to understand why the Amicus and PowerPong motors don't change speed fast enough. They have low power supplies. Amicus has an average power of about 60 watts, PowerPong has a 24 volt 3 amp (72 watt) power supply. Tennirobo and rdv have brushless motors...

That would be good. Can I ask you to record a video of how the robot sends balls to the racket as in the video (https://youtu.be/x8-pdEkS9x4).

Are you serious? For me, there is very little difference between backspin and topspin.

You understood me wrong. In your first video, you have some balls flying with strong topspin, and then some balls with strong bottomspin. But I am interested in the alternation of such balls. One ball with strong topspin, the next ball with strong bottomspin. I have never seen such a video with...

The robot that I like Robo-pong 4050 XL. He can change strong rotations at a good pace. But it's not for sale. The man upgraded his Newgy Robopong. Video on YouTube "Robopong 4050 XL".

Thanks everyone for the replies. The Chinese variants of Omni and Omni-Pro are noteworthy. But there is little information and reviews of the owners about them. Maybe they have low power motors? No motor reversal? I don’t know how to buy on Taobao, usually I buy goods from China on Aliexpress...

I live in a small town and sometimes I have no one to play with. I can come to the hall and practice the serve. But I get bored of it quickly. If I buy a robot, I will play with it.

I can't choose a robot. I want the robot to be able to send balls with slow speed and strong rotation. I think it needs a roller motor reverse. For example, for topspin with strong spin, the bottom motor should spin backwards and the top motor should spin forward. For a ball with strong bottom...
