Trainerbot may be the ping pong and table tennis coach you always wanted

Ever felt like you would use a extremely expert opponent to enhance your ping pong sport? Trainerbot is “the world’s first sensible ping pong robotic” that claims to simulate particular photographs and video games to assist gamers at any stage follow and get higher.

Just like how a batting cage hurls baseballs out like a pitcher, the Trainerbot sends ping pong balls at you want some type of robotic Forest Gump. The one distinction is that it’s completely programmable by means of an accompanying app, letting gamers choose and select virtually each side of the kind of sport they need. With a Kickstarter crowdfunding marketing campaign now underway, Digital Traits picked up a paddle and obtained a harsh lesson in how calculated this bot actually is.

Bucket of balls

The superior prototype we obtained to check out is basically going to be the ultimate design, save for some operational hiccups we observed alongside the best way that may require fixing. It’s a bucket-style design that holds as much as 30 balls, with 5 motors inside that spit them out at various speeds based mostly on intervals programmed by means of the app. Of the 2 variations that shall be accessible, the Fundamental one sits on the table, whereas the Professional comes with a stand that clamps onto the tip of the table. The latter is the one we obtained to play with.

Pretty light-weight, and sufficiently small to suit right into a backpack or duffle bag, the Trainerbot is certainly transportable sufficient to take to a pal’s house and even to a rec heart or office with a ping pong table. Each variations are common that method, as any table must be suitable, and the setup solely takes a couple of minute, assuming an influence outlet is close by.

Designed and co-founded by brothers Alexander and Harrison Chen, every of which left Taiwan and studied at totally different universities in California and Toronto, Trainerbot was born out of frustration. The 2 inventors got here up with the concept as a result of they weren’t capable of play one another. Irritated by an absence of appropriate and constant opponents to maintain enhancing, they figured a robotic might step in as an alternative.

“When you had a shot that stored beating me on a regular basis, I might program that shot and spin into the app, secretly follow at house, after which counter it the following time we meet,” says Alexander Chen. “Catching a serve is one factor, but when there are solely 3 ways to take action, you may discover ways to deal with all of them. Or you would arrange a serve to follow your personal returns.”

App-based coaching

What’s most attention-grabbing in regards to the Trainerbot is how the app customizes play by controlling the 5 motors inside. Dividing the participant’s aspect of the table into 9 sections, it’s potential to program a sequence the place the ball will land in the identical part every time, in a collection of various sections, and even randomly. Topspin, backspin, sidespin, and 5 different spin varieties can be chosen. After which there’s the interval at which the balls could be spit out, going as quick as zero.four seconds between every one.

It’s a bucket-style design that holds as much as 30 balls, with 5 motors inside that spit them out.

Past that’s approach. Returning serve, overhand smashes, fast forehand-to-backhand rallies, and way more are inside attain. The Chen brothers say the app can also be meant to be a repository for members to design their very own customized modes, the place they might modify shot frequency (time between every ball), angle, and table part. It’s an attention-grabbing technique to strive replaying a situation which will have occurred in an precise real-life match between professionals.

To not point out an arch-nemesis opponent. Trick photographs utilized by others could be replicated — or no less than you may strive — by means of the app to follow the best way to take care of them. We determine these are the type of options aspiring and superior gamers will actually take to, since ping pong is a such a sport of inches when performed at a excessive stage.

“The cool half in utilizing the robotic is that it may be personalised to your stage of play,” stated Alexander Chen. “Among the modes within the app are based mostly on YouTube. We’d watch a video on there, see the place and the way rapidly the ball lands, and add it in order that we might follow the best way to higher play that shot or sequence.”

After all, the Trainerbot by no means instructed us how effectively or poorly we hit the ball. For that, we had to make use of our personal eyes. So, in that respect, the unit was merely an automatic server that shot the balls over to be hit in any which method. The spins used, nevertheless, have been spectacular. A sidespin was very a lot as marketed, fooling us utterly on the primary run. The speedy hearth classes, which the Chens referred to as “loopy mode”, have been additionally fairly overwhelming.

The app doesn’t appear to trace something as a result of there’s no method for it to evaluate approach or efficiency in an empirical method. That’s why the Trainerbot capabilities extra like a sensible batting cage than app-based follow trackers from the likes of Zepp Labs and 94Fifty that measure the mechanics of swinging a golf membership, bat, racquet or taking pictures a basketball.

The community is meant to do this as an alternative. By evaluating notes with different gamers, in what they’re calling “the primary social and linked coaching for ping pong”, human suggestions and help stands in for analytics.

Nuts and bolts

The unit wasn’t with out a few hiccups, which the Chens assured us shall be mounted within the closing model going to backers. Trainerbot typically stuttered between shot intervals, and there was a noticeable delay earlier than spitting out the primary ball. The robotic’s jerky movement when reorienting itself additionally wasn’t all that fairly, however these are all going to be remedied, the 2 co-founders stated.

Throughout sequences the place the Trainerbot needed to transfer from one aspect to a different, or up or down to alter the path or trajectory of a shot, it was pretty fast, however could possibly be quicker. For instance, actually quick intervals between balls are tougher to do when the robotic has to change from one aspect to a different. Making up for which can be drills that spit out balls in speedy succession, based mostly on the set interval time, to follow response time. Whereas placement was much less essential in that individual case, no less than for us, being fast and making good contact with the ball was the principle objective.

The app shall be free for iOS and Android, and apparently, each shall be up to date concurrently due to the unified code they’re utilizing. The consumer interface might get a slight facelift between now and the primary batch of models that go to backers.


On the finish of the day, the Trainerbot is certainly an fanatic product, however we felt that it had a excessive sufficient “enjoyable issue” to be engaging to ping pong gamers at any stage. If in case you have a table at house, this can be a good technique to get extra motion out of it when no human beings are round to play in opposition to. Assuming the co-founders deal with the problems we famous, it’s a robotic we will see making some gamers higher.

The Kickstarter marketing campaign is stay now, beginning at $329 for a Fundamental mannequin, and $379 for a Professional mannequin, with delivery in March 2017.
