Set up a online EV3 game ?

[jlivingstonsg]

-------------------------------------

Hi.

I build telerobots as a hobby and some is in LEGO EV3.

https://youtube.com/playlist?list=PLi0zyNfBMXA8SMBR8jWbhCJ7RWjkjBnN_

Would it be interesting to set up a room with some of these EV3 robots and let people log in from all over the world and have games with them?

With a simple cheap code/device ,  I have also been able to control my robots  over the phone network ,   with no wifi.   :) 

So if you dont have any wifi these robots can be placed anywhere on earth if you are able to make a phone call there.    :)  

If anyone here have lots of these EV3 systems and have a place for a robot arena, 

then I would be glad to explain how to build them and set it all up.

Hi,

This sounds like an interesting idea. I have stored my EV3 at the moment, so it's not for me at the moment.

It would be interesting to see this come to life.

Lets try to find people who have EV3 in a city and set up a arena with some robots?

I have a code on Github who can manage the IP queue that I used some years ago that need a update.

and then with a power floor they can be running 24/7.   :)

thing is that when making the robots and things someone needs to pay for power and for keeping it running (because when making a sumo battle just imagine the chaos when robots start to do flips.

maybe try renting or using the place from a robotics centre which uses lego? im quite sure there are many (also there is something like this called isotopium Chernobyl

I know about 2  remote controlled game pages.

Kiev/Ukrain

https://www.isotopium.com/

and 

Finland

https://www.surrogate.tv/

Anyone know any other webpage?

.............................

There is a war in Kiev / Ukraina at 

https://www.remotegames.net/

https://www.isotopium.com/

so they try to shoot Russians now probably.

I will try to contact other tech unions.

oop i didnt notice the location :P good luck locating the others though hope you can get it set up soon!

just curious how did you sync the motors to some online controller? (I want to create a sort of minigame in my room using this system and my current moc)

Do you want to use raspberry pi , arduino or a android phone ?

I use Android phone and a app called robocam

https://play.google.com/store/apps/details?id=ru.proghouse.robocam

to show kids tey can do it with a phone and a LEGO robot.

The robocam app give you a IP adress so anyone in your local router wifi network can open a browser and get video stream and control to the IP link.

If you want to control from outside your local wifi you need to open port in router called port forward or open DMZ in your router.

Read about robocam and see youtube videos to learn.

Questions?

Then get back to me.

i probably will use a raspberry pi also how could you control it? i see in your video you simply watch the stream and control the joysticks but I don't see any wires connected to the phone?

The android app called "RoboCam" ,  make the phone to a wifi network camera.

So you build a LEGO Mindstorms EV3 robot.

Then you put your phone on the robot.

The app RoboCam communicate to the EV3 with Bluetooth.

RoboCam  also connect to your local wifi  and create a web link that any devise in your local wifi, with a browser,  can log in to.

So with a computer or phone, with browser,

in your local wifi ,  you get a video stream webpage and also controls in the webpage.

If you want to control your robot from another city or country you need to open a port or dmz in your router.

 

The same can be done with raspberry pi or arduino and other circuits.

ah just curious how would i do it if I had 2 ev3 robots? (my project is one bottom tank base with 4 large motors and a top ev3 with a 3 DOF robot arm

 

I might need a little help as I cant seem to figure out how to use the app I've gotten it to somehow work with my Chromebook and bad phone but I cant seem to figure out how the controls work and what the settings do if you could help thanks! by the way the thing I'm trying to do is make my robot work so right now what I want is for w to move the motors b and c and for s to move b and c in reverse and for q to move a and d forward and a to move them in reverse if you could teach me how tobocam works that would be highly appreciated thanks!

Did you read all text on Google Play / RoboCam ?

https://play.google.com/store/apps/details?id=ru.proghouse.robocam&hl=sv&gl=US

The developer of RoboCam have a webpage on how to set up the RoboCam.

Please translate the webpage with Google translate in your browser.

http://www.proghouse.ru/tags/robocam

He also have great information on coding it.

http://www.proghouse.ru/tags/programming-tutorials

http://www.proghouse.ru/tags/tutorials-on-using-programs

-----------------

Probably best to create more ports on EV3.

http://www.mindsensors.com/blog/how-to/attach-mulitple-sensors-to-a-single-ev3-port

 

Then you need to set up more mailboxes in settings in RoboCam 

and then code your own program in this

https://www.youtube.com/watch?v=gbaYTZtptOg

or this

https://www.youtube.com/watch?v=4yU5H5g0xLA

that you then upload to your EV3 

and then you write in the file name of your EV3 program in RoboCam 

so that it is activated when starting your robot system.
