The supporting structure 102 may be a groove or a base to accommodate the Portable device 2, and the supporting structure 102 can be designed as a part of appearance of the main body 100. For example, the hands or the legs of the main body 100 are used to clamp the Portable device 2.
The Robot 1 can be used to accompany children, the old or pets. The Robot 1 plays the digital media data via a loudspeaker, gestures and a media playing unit of the Portable device, such as playing music, singing nursery rhymes, telling stories, acting body movements and making expressions. Moreover, the Robot 1 can interact with the user. The user can order the Robot 1 to perform various tasks via sound control, gesture control and remote control. The Robot 1 can also display its current state via the media playing unit 200 of the Portable device 2, and express its mood or state to the user via the body movements.
The user disposes the Portable device 2 at the main body 100 via the supporting structure 102, and when the Portable device 2 is disposed at the supporting structure 102, the main body 100 and the media playing unit 200 play the digital media data. When the Portable device 2 is detached from the supporting structure 102, the Portable device 2 and the main body 100 can operate independently. The Portable device 2 may be a mobile phone, a personal digital assistant (PDA) or a PAD device.
The digital media data are stored in a memory unit of the main body 100, and the Portable device 2 can fetch the digital media data via the memory unit of the main body 100 and play contents according the data. Additionally, the memory unit also stores various applications to enable the Robot 1 to provide interaction functions. The digital media data may be teaching material designed specifically for children or according to requirements.
When the Portable device 2 is disposed at the main body 100, the media playing unit 200 can be regarded as a part of the main body 100 and cooperate with the main body 100 to play the digital media data. The Portable device 2 can be used as a control panel of the main body 100. The main body 100 can interact with the user via the media playing unit 200, and can also display the digital media data and the application vividly via the media playing unit 200 and provide interesting touch interaction. When the Robot 1 accompanies the children, it helps the children learn Chinese, math, encyclopedia, music, drawing and puzzles. When the Robot 1 accompanies the old, the media and interaction at the media playing unit 200 entertains the users better. Moreover, the connection of the main body 100 and the media playing unit 200 can also provide a video communication function.
The main body 100 can interact with the user via the media playing unit 200, and when the Portable device 2 is detached from the main body 100, the main body 100 can execute various functions without a display. The main body 100 communicates with the user via voice and visual technology, identifies identity of the user via voice or image and executes relating conversation and chatting. Furthermore, the main body 100 interacts with the user via vivid body movements and expressions. It can tell stories, play nursery rhymes and music, or play easy somatic games with the user. The main body 100 monitors home environment and has a voice call function. The main body 100 can also take pictures and transmit images to the Portable device 2 to monitor the home environment or make video calls.
When the main body 100 and the Portable device 2 are separate, the two devices can operate independently and provide original functions. For example, the Portable device 2 may be a mobile phone, a PDA or a PAD device, and the user can still use it to make a phone call, process data, play video and execute software. The Portable device 2 is not limited to cooperate with the main body 100 and is not limited to provide the digital media data or the application of the main body 100. Furthermore, the Portable device 2 can remotely control the main body 100 via wireless communication.

The users operate the Portable device 2c and 2d to fetch the internal resources, such as the digital media data, the media data, commercial data and game data, of the main body 100 via the wireless transmission.
The Portable device and the main body can operate at one of following modes selectively: the first mode is that when the Portable device is attached to the main body, they are combined and cooperate with each other. The second mode is that when the Portable device and the main body are separated, they can play the contents of the digital media. The third mode is that when the Portable device and the main body are separated, they operate independently to process unrelated data and provide original functions.
As stated above, the Robot can play contents of digital media. In areas where the main body cannot reach, the user can detach the Portable device from the main body to use most functions and digital contents of the main body. Consequently, the Portable device broadens the interaction area between the main body and the user, and the interaction area is not limited to the moving area of the main body. Moreover, the main body and the Portable device still keep original functions and operate independently, and the Portable device does not need to cooperate with the main body. Thus, usage of the Portable device is extended.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
