There is no 1-to-1 mapping of the Pongbot values (speed 0-10, spin 0-10) to speeds of the two wheels. The pongbot app does quite some math to translate these scales: you can see that the allowed maximum spin depends on drop point, ball height and speed. I don't see how to recreate those simpler...

You can learn anything! Refer to this post, where I answered a similar question.

you can define a pause time inbetween runs through a drill. Pauses inbetween balls within the drill can only be done by twiddling the frequency values (0-100%, corresponding to 30-90 balls per minute). you can have as many balls per line as you want, separated by the | character. If you want to...

I don't really understand your proposal. Also, I can do software, not hardware. If you modify the hardware, the firmware of the bot itself would need to be updated, such that the parts can be controlled. Since we don't have access to the proprietary firmware, we won't be able to change it

Well, here we hit the issue of how to keep the hardware itself safe: The wheel itself doesn't actually rotate with speeds <500 rpm, which means, each ball will contact a stationary wheel at the exact same position every time, leading to increased wear and tear at this part of the wheel. This...

Doh!... Good catch @plunder Indeed, I had 5/5 as calibration set in the original Pongbot app. So all balls were lower and more to the forehand side. I sat down and recorded all drills again with the default calibration 0/0. Forehand and backhand are now symetric (parameter drop-point). The new...

Hi! I didn't have time to continue working on the webclient, but it seems, that having predefined "interesting" balls and drills is quite helpful. As an inspiration for easier experiments, I translated (hopefully) all builtin drills of the app into the format used by the webclient. Each line has...

I added slight modifications to the webclient: simple drills with no variations (one ball definition per line), no pause (set to 0) and not more than 9 balls will be handled by the bot itself (so in these simple drills no more stops showing two blue lights, no small hiccup between stopping...

Hi everyone! I put up a new version of the custom novabot client. It has a number of new features: unlimited balls per drill: you can add as many balls as you like. Internally the client will send a list of individual custom drills, that is never longer than 6 balls each. random ball selection...

This depends on whether or not Chrome allows more than one connection at a time. I don't see, why not, worth a try if you have access to more than one bot. From a players perspective, synchronizing the balls from both bots might be an issue: the only mechanism available would by synchronizing...

Regarding the error message: The error makes sense for this older version of android. I'm afraid, since the code is just a prototype, I won't be able to provide support for all devices. If your tablet works, I hope that is enough? Regarding the ball settings: It is possible to record the drill...

There were two main parts to this: reverse engineer the source code of the pongbot app via Blutter (it is a Dart app, so the resulting decompilation will be ARM assembler code with some dart specific comments). I mainly used this to confirm theories I developed using step 2, as well as the...

I added some instructions to the web page. You will need to enable bluetooth, mobile data or Wifi is not necessary for the communication with the Nova bot. Random sequence does not work yet, I need to investigate, probably next week or so. Saving drills is not yet supported, you will have to...

Hi all NovaProS users! Thank you, @plunder for your comprehensive work on the Pongbot Nova S pro. I enjoyed your posts very much. Since I was curious I analyzed the bluetooth protocol used by the pongbot app and I think I found some interesting stuff: the communication itself is not...
