    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.

    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.

    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.

    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.

    https://github.com/jlivingstonsg/waiting-room-to-telerobot

    http://robot1.gamereality.se/index.php

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

    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.

    When I was young and fanatic LEGO builder we played games like Tetris to train our ability to build LEGO.

    There were released a game 1989 that was a 3D Tetris,

    that I now have found again, as an online game for browser with no download.

     

    Just Google:   BlockOut online
    and you can try one,  in your browser.

    https://blockout.nu


    Here is how you set it up in level "Out of control".

    Lets have a competition.

    Can you beat me?

    Hi.

    I use a android app called RoboCam 

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

    and the developer said he did it with LEGO developer kits.

    https://education.lego.com/en-us/support/mindstorms-ev3/developer-kits

    I make now a website

    http://robot1.gamereality.se/

    that I want to send commands to my robot from.

    https://www.youtube.com/watch?v=TZ4ujKcy87o

    I use "MailBox" when controlling the robot that recieve drive data.

    Does anybody know how to make some  javascript  code lines that send a number to a "MailBox" when a key is pressed ??

    Hi.

    I finally managed to build my EV3 omni/holonimic telerobot with anti collision-system. If you drive to close to anything it stop and reverse a bit, if needed. Sensitivity and reverse is adjustable.

    I will equippe them with laser tag weapons and laser aim system and so on.

    Ol2gkzL3Tl.gif

    It can be remote controlled over the internet with live camera stream, so it is a internet camera robot, (that moves like a computer avatar in FPS computer game).

    It can be controlled over the internet from a mobile phone, ipad or computer, from a browser.

    I plan to build a internet game so that you can log in to robots and have a game with them like in https://www.isotopium.com/  . 

    I did this on ADSL already 2005 and had people playing with my robots from all over the world.

    Here is one guy in Australia that explain how it was 2005.

    https://web.archive.org/web/20080220221155/http://www.roaringsnake.com/misc/article_tank.htm#

     

    You can build it  your selfe. 

    You need a

    1. Mindstorms robot 

    2. Building instructions.  http://thetechnicgear.com/2014/04/howto-build-3-wheels-holonomic-robot-using-lego/

    3. An android phone with a Google app called RoboCam.   https://play.google.com/store/apps/details?id=ru.proghouse.robocam&hl=en_US   

    4. 3 Omni wheels and 3 Large Servo Motor.

    5. 4 Ultrasonic Sensors

    Hi.

    There is again a good telerobotics app for android called RoboCam.
    https://play.google.com/store/apps/details?id=ru.proghouse.robocam&hl=en_US

    You build a Mindstorm's EV3 robot and tape/glue on an android mobile.
    The mobile connects with Bluetooth to EV3 and then with wifi to the internet.
    It can then be remotely controlled from other countries from a mobile or computer in a browser.
    Here is some collected info from their website about their app development.
    http://www.proghouse.ru/tags/robocam
    Translate it with Google translate.
    https://translate.google.com

    It is not in open source as CellBots was released in 2009.

    www.cellbots.com

    The thing is now that I want to build so it can control a holonomic robot ie a robot with 3 omni wheels.
    I encoded CellBots that was in Java 2014. See my movie.
    https://www.youtube.com/watch?v=skD91m5jRX8

    Now my question is.
    Can anyone give me some tips or help to fix a holonomic stearing of the RoboCam app?

    I have asked those who made RoboCam on their site and they say that you should be able to do this with mailboxes.
    See my discussion at the bottom of this page.
    http://www.proghouse.ru/article-box/92-robocam

    Anyone that can help me ?
