Using RoboCam you can FPV control your own LEGO Mindstorms EV3, Android or Raspberry Pi robot.

Quick start guide (only for those who have an educational kit of LEGO Mindstorms EV3 (45544)):

1. Assemble Researcher EV3 (the instruction: https://goo.gl/yPU4sa), turn it on and make sure that Bluetooth is working.
2. Install RoboCam app on a smartphone (hereinafter, Phone 1).
3. Turn Bluetooth of Phone 1 on and make sure that Phone 1 and EV3 are connected via Bluetooth (they must be paired).
4. Connect Phone 1 and smartphone that you will use to control the robot (hereinafter, Phone 2) to the same Wi-Fi-router.
5. Start a RoboCam server. For this push the left green button.
6. Connect Phone 1 to the robot. For this push the magenta button in the middle.
7. Open Google Chrome on Phone 2 and go to the link that is shown in RoboCam app on Phone 1.
8. on Phone 2 (by default use and 123).
9. On Phone 2 appear two joysticks and video from camera of Phone 1. Lock the phone and attach it to the robot.
10. Now you can control your robot via Phone 2.

If you have a home kit of LEGO Mindstorms EV3 (31313) or you want to control other EV3 robot instead of Researcher EV3, you need to set up RoboCam app. See RoboCam settings.

To use the application you need to know two things: how to set up the connection and how the control happens.

That's the quick manual on setting the standard connection. Need: EV3 robot, Android-smartphone with the installed RoboCam (hereinafter, Phone 1) and the smartphone or tablet (Android, iOS or Windows) with a modern browser that's ed HTML5 (hereinafter, the Phone 2). Phone 1 is connected to the EV3 via Bluetooth (devices must be pre-paired!). After starting RoboCam server on Phone 1 and connecting Phone 1 and Phone 2 to the same WiFi-router, you can connect to RoboCam server (to Phone 1) via browser (from Phone 2). To do this, you need to write the address into the browser address field that will be shown in RoboCam for example, http://192.168.1.2:8088

That's the brief description of how the control happens. After connecting to the RoboCam server through a browser of Phone 2 and entering the RoboCam Web application, you will see everything the camera of Phone 1 sees. Attach Phone 1 to your robot, so its camera is directed forward. Web app on Phone 2 can have from 1 to 4 joysticks to control the robot depending on the settings. When you touch the joystick, the coordinates of the touch points are transferred to the RoboCam application on Phone 1 and then, depending on the joystick settings, they are transformed to the EV3 motor commands or sent to EV3 mailboxes. If the coordinates are sent to mailboxes, you need to write an additional EV3 program for processing of them. Names of the mailboxes are following: x and y - joystick 1, w and z - joystick 2, a and b - joystick 3, c and d - joystick 4.

By default, the application has a setting for only one of the robot - "EV3 Researcher», which you can see on the video. You can assemble EV3 Researcher from an educational kit of LEGO Mindstorms EV3 (45544). link researcher's build circuits: https://goo.gl/yPU4sa
