If you don't want to use default BotEyes web application based on WebRTC, you can use Microsoft Skype. The best way for this option is to use desktop computer. Tablet or smartphone you can use too, but it is not very convenient.
First, you need to install two instance of Skype: one to your controlling gadget and other one in the tablet in robot head. You can use Skype as it is written in Skype manual.
If you want, you can set Skype auto answer for Skype in telepresence robot's head. Go to your Skype profile (Click profile icon) "Settings"/"Calling"/"Answer incoming call automatically" and "Start my video automatically". See it in video below:
Next, go to "Settings" page in BotEyes website ("Gear" button in left bottom of calling page), input there name of robot's Skype in field "Callee Skype Name" and press the button "Set for Skype", then "OK, go back".
If you want to refuse Skype settings, click "Reset to Defaults" button.
If you want to use desktop computer to control robot you can use any web browser, but the best suited is Google Chrome.
To view video from the telepresence robot, open Skype application in robot head and in remote client.
Open robot control site in your browser and enter login and password assigned before, and press "Login" button. You will see the new small window with robot control circle and simultaneously the Skype will be opened. If you press in green sector robot go forward, if in red sector - go back, in yellow sector - it will turn. The more far from circle center, the faster speed. The arrows allow tilting the telepresence robot head.
If the telepresence robot control circle doesn't appear, you need to check if the popup blocked for BotEyes.com site is disabled.
Now you can drive anywhere and see what you want. To prevent robot collision with other objects, tilt the camera down to see the telepresence robot wheels base. It can be done using green arrows in right side of robot control circle. You can see how to control the telepresence robot in video below:
Android is single-window OS and it is the main difference between Skype using in Andoid and Windows.
Enter robot control website and open Skype. Connect client's Skype to Skype in robot. After this, you will have two apps opened: Skype and web browser. However, you need to see it on the same screen simultaneously. There are two options to do that.
You can turn On "Settings/Advanced features/Multi window/Pop-up view action/On" in your tablet (this option may looks different for different OS versions):
To make the browser window small and located at the bottom right of the screen, swipe diagonally from the top left corner of the screen when the browser is in full screen mode like in video above (this video is for Android 7).
You can use "Settings/Advanced features/Multi window/Split screen view action/On" in your tablet (this option may look different for different OS versions) and this give you Skype and browser view like in video here:

To use BotEyes with Skype you need two independent applications: one for tablet camera and another for the telepresence robot movement control. Therefore, robot control is possible only on those iOS-devices that allow opening and seeing two applications simultaneously. This mode in iOS is named "Split View" and available on iPAD only starting from OS9 version, in model iPad Pro, iPad Mini 4 and iPad Air 2.
So, we assume that you have iOS9 or above and it is installed on iPad.
Divide screen into two parts using your iPAD manual. In one part, you need to open Skype to view video from robot, and any browser in the right part of screen. The best-suited browser is Google Chrome.
If robot control circle doesn't appear, you need to check if the "popup blocked" for BotEyes.com site is disabled.
Now you can drive anywhere and see what you want. To prevent telepresence robot collision with other objects, tilt the camera down to see the robot wheels base. You can do it using green arrows in right side of the robot control circle. You can see how to control telepresence robot in multiple videos above.
