BT-Remote, Remote control your LEGO Spike Prime & Robot Inventor self-uprighting balancing robots.

Nice work! They are so small and cute, and also very stable!

[@Unbrickme]

This is awesome! OMG Laurens Valk contributed to the project!!! He is absolutely legendary!!! He made so many self balancing Segway robots and his blog on robot square is epic! I own pretty much all of his books, and I built almost every robot he ever published instructions for. If you see my message, please tell Laurens Valk that I'm a massive fan!!!

Heel vloeiende bewegingen Dimi, geen evidentie om dat te realiseren. Mooi werk van dé LEGO master

You are absolutely amazing👏🏻👏🏻👏🏻👏🏻

This is so cool!

[@bouwgabbers]

Awesome Dimitri!!!

[@alexclewett869]

I'd really like to be able to show this off at an Eistedfodd soon. Have you done this using the hub to hub blocks in Mindstorms Robot inventor?

[@DimitriDekyvere]

I think it is possible with the Robot Inventor hub2hub blocks. But here i used Nard his python hub2hub communication library.

[@need4baum]

Awesome! your idea always crazy me ^^*

[@MelonOnionIce]

Can you make a whole tutorial on how to do the coding

[@DimitriDekyvere]

I plan to make this a 3h class for my subject Mechatronics in Vives university college. If you are from around here you can sign up for this course. :-) Maybe I'll make a tutorial video when that lesson is done.

[@Mocsfromscratch]

That is super cool

[@girishbh7816]

HI, just wondering if somehow you can have the code on PC and use a phone to control?

[@DimitriDekyvere]

Now we have found how we can make 2 hubs communicate, it should be possible to replace the remote with a smart bluetooth device. That will be one of our next projects. (I have already seen some promissing tests from Nard. 😉 )

[@hutte-y1p]

What is control+ and what program to install on each hub?

[@MelonOnionIce]

Can you also make a tutorial on how to link them

[@DimitriDekyvere]

There is a very detailed explanation of this linking of hubs on Nard's page: hubmodule.readthedocs.io/en/latest/hub2hub/ There are also examples of how this works.

[@tuankiettran8811]

Thanks.

[@sebastiansorano8025]

Awesome job! I only have access to 1 Robot inventor hub. Do you know if the boost hub could be used as the remote control for hub to hub communication instead?

[@DimitriDekyvere]

I have not tried with the boost hub, but i have a working control+ hub remote now. (Stil working on the video)

[@Rixin13]

@@DimitriDekyvere still workinprogres?

[@DimitriDekyvere]

@@Rixin13 hmmm. Not realy. I have a set of working balancers with control+ remotes. But i didn't make the video because a new Spike firmware update broke the communication code. It works perfectly when you have the old Spike firmware, but it seems silly to install old firmware on your hub, so i gave up making the video... i can send you the code if you want it.

[@Rixin13]

@@DimitriDekyvere thanks for swift awnser, yea sure, ill be glad if i can examine your code. Im looking for a way to control PUp hub vehicle with mindstorms based remote.

[@DimitriDekyvere]

@@Rixin13 I have added the Control+ remote control files to this webpage: legostudiovives.be/balancing_lego_robots/ But maybe remote control using Pybricks is a better option now?

[@GubstersGarage]

Nice work! Where can I get those configurable tracks?

[@DimitriDekyvere]

Haha, I'm glad you noticed the configurable tracks 😊, I made them especially for this movie. (But of course will be able to use them at events later.) I needed a track that is forgiving for those who get off the track, but still creates a small obstacle to get back on it. (And that can be built up and down quickly in different shapes + easy to carry around.) So buying them will be a bit difficult. :-) But if you have access to a laser cutter you can very easily make them yourself. I went to the local woodshop to buy 2 white hardboard sheets of 244 x 122 cm (=20 euros), drew some racetrack puzzle pieces and cut them out with the laser cutter in our Vives Maaklab. If you don’t live far away I can make some for you, or I can provide you with my digital laser cut files.

[@MortenEnemarkLund]

Great work. My kids only have one Mindstorms set (51515). Would it be an idea to show how to use an xbox controller as a remote instead?

[@DimitriDekyvere]

I am working on a LEGO control+ hub remote with Nard at the moment. Coming soon.

[@hydroworld-soontobemigrate6160]

Does this remote control solution only work for two hubs of different types (in other words, can you use one Robot Inventor hub to control another Robot Inventor hub?

[@DimitriDekyvere]

No, it works with every hub. If you take a good look at the race at the end, you will see that there it are the hubs of the same kind that are connected. But for now all of them run on Spike Prime firmware.

[@hydroworld-soontobemigrate6160]

@@DimitriDekyvere Got it, thanks! That will really help me control my new flying Mindstorms robot!

[@hydroworld-soontobemigrate6160]

It will be at least two years to fund before it's completely finished, but you will get an opportunity to see it, probably in Summer 2023. It'll be worth the wait!

[@hydroworld-soontobemigrate6160]

Oh, and I have one more question: Is there a way to automate this remote control setup, or to make one hub operate another hub without you controlling it yourself? (Like Bluetooth daisy-chaining?)

[@satan4768]

Hmm I would have to buy 2 more hubs to make 2 jousting segway walle robots talllyy hoooo will have to save up thanks for the brain jiblet work 10/10 so I'm guessing using a xbox controller is impossible to do with refresh rate no work around?

[@DimitriDekyvere]

It should be possible to use a smartphone or some other bluetooth device. Now we have found how to communicate from hub 2 hub, we could try to replace the sender by an other bluetooth controller. Unfortunatly the Mindstorms app only alows RC communication in streaming mode.

[@a.m.641]

Do you know if there's a way to connect a Spike Prime hub to an Xbox controller?

[@DimitriDekyvere]

Yes, that is possible if you use the Mindstorms Robot Inventor app (and download RI firmware to your Spike Hub)

[@sdesnakecarlos5797]

Have you got the block code?

[@DimitriDekyvere]

The buildinginstructions and demo programs (Spike V2 app) are on my website. See video description. legostudiovives.be/bouwideeen/

[@girishbh7816]

Does hub to hub work on other powered up devices too?

[@DimitriDekyvere]

Yes it does, but you need Nard his python library to do thay.

[@-assasin-9787]

everything was fine with me, but in the end the hubs couldn't connect, what to do?

[@DimitriDekyvere]

If connecting fails, try rebooting both hubs. (And make sure you have the right firmware installed on both hubs. Unfortunatly Nard his library doesn't work on the new firmware yet.)
