TenniRobo has been graduated from YC Startup school 2018

In August 2018 Tennirobo was selected to attend the Startup School program from Y Combinator (advisor track with real mentors from YC). A few days ago the last office hours were held, and now I'm proud to be graduated - here is the link to our company at SUS website 
These 2 months were very special - not only because I was able to get useful advice from mentors, but also due an opportunity to communicate with other startups from the whole world.
Thank you, guys!

My interview about the development of TenniRobo: from the initial idea to the present day

Hey guys!
Recently I had an interview with Davis Baer, the co-founder of OneUp and, also, a Hacker Noon writer. If you find the TenniRobo project interesting, then probably you may like this conversation as well. We were talking with Davis about how I started working on the robot and what motivated me the most, about how the project is doing at the moment and what are my plans for the future.

Extract: As a table tennis player, I thought that a robot that ‘knows’ how to serve balls like a coach would be a good option in this situation. But as the research has shown the actually good robots are too complex and too expensive, and the cheap ones do not have the necessary functions. Moreover, even the expensive machines are often unable to provide “human-like” ball behavior. So, suddenly, it became clear that many table tennis players have the same problem of choice.
In a few months, the first primitive but working prototype was ready to use. Apparently, the local community was captivated …

TenniRobo - how to create single shot

It’s time to get a little bit closer to the continuous and effective drills with TenniRobo! The latest video tutorial shows how easily you can set up a single shot via the dedicated application on your smartphone. Just take a look! The accuracy of a robot is quite impressive, isn’t it?

Let's get started with TenniRobo tutorials

Dear friends,
I want to announce the release of a series of video tutorials on the basics of TenniRobo control. These small instructions should answer all possible questions that may arise while you’ll be turning your robot into a personal sparring partner. Short and informative - that’s what I wanted them to be, and I truly hope I’ve succeeded.

We’ll cover technical questions related to both the mechanics of the robot and the features of TenniRobo application. Also, I’d like to note that it's quite easy to figure everything out by trial and error. But these video-hints will definitely save your time, and I strongly recommend you to pay some attention to them.

The first three lessons are already on the YouTube!
1) How to get started with TenniRobo 2) How to connect the Bluetooth 3) How to setup ball’s parameters Subscribe and watch out for updates!

TenniRobo 180 vs 100 balls versions - comparison for custom drill

It’s time for me to explain in more details the reasons, why I think the extension of a basket is so important for the robot. As you probably remember, some people already use robots from my first batch, and I carefully analyze their feedback. Almost all of them said that they really want to have a bigger basket for balls.

You probably agree, that when you are trying to bring to perfection some technical element – each additional ball matters a lot. But it’s even more frustrating when the element just starts to work out (you've been going to this for so long!) and the basket suddenly appears to be empty.

Obviously, you have to stop and then start again, which results in loss of pace. I know that there are some compact robots on the market with the baskets that contain no more than 30 balls. Maybe it would be enough for somebody, but I can not imagine effective training with such kind of equipment.

Let’s make some calculations! In an ordinary game, even an amateur player takes abo…

TenniRobo got a bigger basket for balls

Today I want to show you the second huge update, which TenniRobo got last month (personally, I think it's very important). The updated TenniRobo has a bigger basket for balls. Its capacity has grown to 180 balls instead of initial 100 balls.

Thus said, from this day TenniRobo exists in 2 versions, and I strongly recommend you to use the second one (extended version) only. The robot's size visually changed only by 25% while it still lightweight and compact. You can put it in a middle-sized backpack, the weight of a robot is comparable to the weight of a usual laptop.


Another advantage of the new version - when it's mounted on the table without a tripod, the "head" can be rotated in any direction. The old version has a restriction - the head can't be tilted down because it touches the table.


Here is a small comparison table for these two versions of our robot:


TenniRobo - 100 balls TenniRobo - 180 balls Dimensions (L-W-H) 250х190х260 mm 9,8х7,5х10,2 inches 290х240х3…

Molded parts for Tennirobo's "head"

This month TenniRobo got two important updates, and today I'm very excited to show you the first update - "head" now consists of molded plastic parts. Here is an example of 3D printed part and molded. Are you able to find the difference? :-)


Why is it so important? Before this day, all my prototypes have been made with 3D printed plastic parts. It's ok for prototypes, but I didn't want to ship robots with these parts to another countries, because there are some chances that these parts would be broken under some conditions (it's a pain of 3D printing technology - bad adhesion between layers can reduce strength of final part). Molded parts are free for this problem, so they are more strength, and I can be confident that they won't be broken in final product.
Also, molded parts can be manufactured much more quiclky, than with 3D printing technology. It means, that I can manufacture more robots for you, dear Tennirobo potential users.
Finally, it just looks…
