The current invention proposes an advance form of exoskeleton for mobile devices formation of various new types of robots that allow solving problems of various classes using additional functional modules within the framework of the EMD concept. It further allows a significant expansion of the functionality of mobile devices, which—with the help of a specialized external frame can move in space and carry out various useful interactions with the outside world using removable working (instrumental) modules. This structure allows to reduce the cost of robotics by using standard mobile devices equipped with appropriate software as operators of various types of exoskeletons. The specified technical result is achieved by combining the functionality of the exoskeleton (a specialized external frame), which allows you to move in space and interact with the environment, and various mobile devices (smartphones, tablets, smartwatches).

A system and method for mirroring and controlling a remote device is disclosed. The system includes a computer, executing a software program. The software program creates a graphic representation of the device on the screen, complete with the user interface, which may include LCD displays, LEDs, push buttons and reset buttons. The user can manipulate any of the buttons disposed on the device by manipulating the pointing device on the computer, and clicking on the button. Further, the software program displays the state of the output devices, such that the user can observe the state of the LEDs and the LCD display without being near the device. By mirroring the device on the computer screen, the user is able to share the information with others, such as via video calls.

Methods, systems, and storage media for receiving a call on a television are disclosed. Exemplary implementations may: receive, at a communication device coupled to the television, a call; generate a message comprising details of the call; send, via a wireless link, the message to the television; cause for display, via the television, the details of the call; receive instructions to accept or reject the call; and initiate the call through the television when the call is accepted.
