[0025] The driving unit 110 is comprised of a motor 113, a motor drive 112 for driving the motor 113, vision processor 116 for capturing and storing a vision in a buffer, flash ROM 114, potentiometer 117, sensor 115 for sensing an outside stimulation and a Digital Signal Processing Unit (DSPU) 111 for decoding a command for implementing a certain motion and transmitting to the motor drive 112.

[0026] The link unit is comprised of physical link means such as the I/O BUS, USB and the RS-232C.

[0027] At this time, as shown in FIG. 2, the link unit can be comprised of the wireless link means. The Wireless link means are connected by mounting wireless module such as the Bluetooth chip or RF modem in the central processing unit 120 and the driving unit 110 respectively.

[0028] The method for driving the toy having a detachable central processing unit will be described as follows.

[0029] The first step of driving the toy in case of the self-control mode is to operate the program stored at the flash memory 122 from the central processing unit 120 and then learned contents operated by the LCD screen and the touch panel 127 are stored in the flash memory 122. The microprocessor 123 transmits a certain motion command to the driving unit 110 reflecting the learned contents. At this time, the microprocessor 123 and the driving unit 110 are connected by the physical link means or wireless link means. Later, if the motion command is transmitted to the driving unit 110 reflecting the learned contents in case of implementing the certain motion according to the learning, the driving unit 110 decodes the command for implementing the certain motion and drives the motor 113 by transmitting it to the motor drive 112.

[0034] FIG. 4 is a block diagram showing the control signal in case of the self-control growth mode according to the present invention and as shown in the drawing, in case the user has the cyber character learn a certain motion/voice using the LCD screen and touch panel 127, the microprocessor 123 outputs a certain voice/sound at the speaker 126 by transmitting a voice/sound generation command to the audio codec 121. The DSPU 111 received an input of a certain motion generation command from the microprocessor 123 controls the motor drive 112 and accordingly, by performing the corresponding motor among a number of motors, the microprocessor implements the certain motion. Therefore, the toy in accordance with the self-control mode shows manner and walking by receiving information inputted from the posture/manner generation unit and then performing the motor, outputs the audio information by receiving information inputted from the voice/sound generation unit and performs vision tracking of a substance by receiving information inputted from the input unit of a camera.

[0035] FIG. 5 is a block diagram showing the control signal in case of the separate growth mode in accordance with the present invention and as shown in the drawing, if the user inputs a certain function using the LCD screen built-in type touch panel, for example, learning, play, meal, excretion and sleep, the microprocessor 123 outputs the voice/sound generation command corresponding to the currently inputted function to the audio codec 121. Accordingly, the microprocessor 123 outputs the voice/sound generated by the audio codec virtually exhibiting the action of the cyber character according to the inputted content on the LCD screen and touch panel 127 and also stores the growth information according to learning in the flash memory 122.

[0036] The growth style of FIG. 5 and FIG. 6 is an example implementing a life in the real world and FIG. 6 is a table showing growth steps in case of the self-control growth mode in accordance with the present invention. As shown in the drawing, the toy exhibits a motion and outputs the voice information according to the growth period and growth step. Also, FIG. 7 is a table showing growth steps in case of the separate growth mode in accordance with the present invention and as shown in the drawing, the cyber character exhibits the actions virtually on the LCD screen and touch panel according to the growth period and growth step and outputs the voice information.

[0037] As apparent from above description in detail, by having a detachable central processing unit 120 and driving unit 110, the present invention can be used to have a cyber character learn a certain motion or voice in the condition of carrying the central processing unit 120 apart from the toy.
