Robot cleaner, and system and method for remotely controlling the same

PURPOSE: A robot cleaner, remote control system of the robot cleaner, and a method, capable of checking state and peripheral status of the robot cleaner in real time are provided to prevent abuse of the robot cleaner by performing connection authentication operation when connecting the robot cleaner through a terminal device. CONSTITUTION: A robot cleaner comprises an image detection unit(110), a communication unit(120), a control unit(130) and a driving unit(140). The image detection unit generates video information by filming surrounding. The communication unit receives a control signal from an external terminal device and transmits the video information to the terminal device. The control unit extracts control order from the control signal and controls the image detection unit according to the control order. The control unit controls the image detection unit to continuously generate the video information for a certain time. The driving unit includes one or more wheel and drives the wheel according to a driving signal. The control unit extracts transfer order from the control signal, generates the driving signal based on the transfer order, and moves according to transfer route.
