Preferred embodiments of the present invention made as described above will be described in more detail with reference to FIGS. 1 to 4.

When the switch 116 mounted at a predetermined position of the robot is turned on to drive the dog-shaped robot, the microprocessor 100 initializes the entire system of the robot according to the program execution of the program 117. (Step; S10).

After the initialization is canceled, the microprocessor 100 receives an RF (Radio Frequenc) command from the first high frequency receiver 101 (step S11) and determines whether the RF command is a voice command or a security mode (step S12). S13) When the received RF command is a voice command, the robot moves and responds to the voice command. In the case of the crime mode, the robot freely moves the room and performs the crime mode.

In other words, if the user needs to use the robot as a security means, the user first turns on the switch 116 and then uses the power key provided in the operation panel 206 of the transmission apparatus 200 shown in FIG. When the key is pressed and then the security mode start key is pressed, the security mode key data is provided to the second modulator 204 through the first control unit 201. The second modulator 204 modulates the security mode data into a RadioFrequenc signal under the control of the first controller 204, and in the power amplifier 205, amplifies the modulated high frequency signal and then powers the antenna. Through ANT2, the robot is sent to the robot at a short distance.

The first high frequency receiver 101 installed in the robot receives a high frequency signal transmitted from the transmitter 200 through an antenna ANT1 serving as a tail of the robot, removes unnecessary noise components, and removes the received high frequency signal. After amplifying to a sufficient size, the original data is extracted, that is, the security mode data is extracted and provided to the microprocessor 100. Therefore, as described above, the microprocessor 100 stores the data input from the first high frequency receiver 101 in the data RAM 118 and searches whether the data is security mode data (step S13). If the result of the search in step ST13 is not the security mode data, the robot enters the free operation mode routine to be described later to perform the free movement or the free movement reaction operation (step S27).

If the result of the search in the step (S13), the security mode to operate the human body sensor 119 installed on the head after a certain time, and also to control the pulse width modulator 103 to generate a pulse width modulated signal. The pulse width modulated signal generated by the pulse width modulator 103 is buffered by the buffer unit 104 and input to the motor driver 105. At this time, the motor driving unit 105 controls the motor 106 installed in the joint, neck joint and tail of each leg of the robot according to the command of the microprocessor 100 to freely move the dog-shaped robot In addition, the microprocessor 100 monitors whether the intruder has invaded from the above-described human body sensor 119 when the dog-shaped robot is free to move (step S14) to check whether the human body is detected (step S15). . If there is no human body detection in step S154, the robot continues to move freely.

When the robot is moving freely in the room, when a signal is detected from the infrared sensor group 108 and the signal stabilization unit 107, that is, the head of the robot is installed above and below the infrared sensor group 108. When a signal is detected from the sensors installed above and below the head sensor and the tail (step S16), it is determined that there is an obstacle or a cliff in the direction in which the robot proceeds, and the motor group 106 is controlled to move the robot backward or forward. By moving (step S17), the free moving operation for continuing the security mode is performed.

In addition, when the robot falls freely to the left or right while moving freely inside the room, it detects a signal from the left or right sensor of the infrared sensor group 108 installed in the body portion of the robot (step S18). When a signal is detected from the left or right sensor of the robot, it is determined that the robot has fallen to either side, and the motor group 106 is controlled to generate the robot (step S19) to continuously perform free movement.

As such, when the robot is performing a free movement operation, when an external intruder is detected and detected by the human body sensor 107, the human body detection signal is amplified by the signal stabilization unit 109 and the waveform is shaped to form a microprocessor 100. The microprocessor 100 confirms the human body detection (step S15) and controls the high frequency communication module, that is, the first phase synchronization loop 114 to generate a local oscillation frequency and an alarm signal. Is provided to the first modulator 113.

The first modulator 113 mixes the alarm signal input from the microprocessor 100 to the local oscillation frequency and transmits the alarm signal to the alarm device 300 located at a short distance through the high frequency transmitter 115 and the antenna ANT1. (Step S20).

As shown in FIG. 3, the alarm device 300 receives the high frequency signal transmitted from the dog-shaped robot through the antenna ANT3, amplifies it to a sufficient size in the second high frequency receiver 310, and restores it. It is provided to grandfather 2320. The demodulator 320 of the alarm device 300 mixes the input high frequency signal and the local oscillation frequency generated by the second phase synchronization loop unit 340 and restores the original alarm signal to the second control unit 330. To provide.

When the alarm signal is input from the demodulator 320, the second controller 330 generates an alarm through the alarm amplifier 350 and the speaker 360, and designates it in advance through the modem unit 370 and the communication line 380. The phone number is dialed to transmit the voice message (step S21).

The alarm generation and voice message transmission stop until the security mode release signal from the transmitting device 200 is input.

As the robot moves freely in the room as described above, an internal emergency situation indicating that an outside intruder has invaded the outside and an alarm are generated, thereby making crime prevention and disaster prevention more rapid.

Thereafter, when the security mode release signal is detected from the transmitter 200 (step S22), the security mode is released (step S23) and the motor group 106 is stopped by driving (step S24).

Next, if a user provides a voice command to the robot to obtain a motion corresponding to the voice command from the robot, the switch 116 is turned on, and then the operation panel 206 of the transmitting apparatus 200 shown in FIG. 2 is turned on. When the provided power key is pressed and the voice is input through the second microphone 202, the amplifier 203 amplifies the electric voice signal to a sufficient magnitude and provides it to the second voice recognition unit 207. The second voice recognition unit 207 recognizes the input voice signal and provides code values corresponding thereto to the second modulator 204. The second modulator 204 modulates the code values corresponding to the voice signal input from the second voice recognition unit 207 to the high frequency signal according to the control signal of the first control unit 201, and the power amplifier 205 After amplifying the high frequency signal modulated and input from the first modulator 204, the high frequency signal is transmitted to the robot at a short distance through the antenna ANT2.

The first high frequency receiver 101 installed in the robot receives the high frequency signal transmitted from the transmitter 200 as in the security mode described above, extracts code values corresponding to the voice signal, and transmits the code values to the microprocessor 100. to provide.

The microprocessor 100 searches whether there is a code value corresponding to the voice command (step ST12). If there is a code value, it is stored in the data RAM 118 and the sound generating means is controlled.

The voice generating means includes a voice memory unit 109, a digital-to-analog converter 110, a low frequency amplifier 111 and a speaker 112. In this case, the voice memory unit 109 outputs voice data corresponding to the code value under the control of the microprocessor 100 (step S25), and the output voice data is output from the digital / analog converter 110. After being converted into an analog audio signal, it is input to the low frequency amplifier 111. The low frequency amplifier 111 low-pass filters the input analog voice signal and amplifies it to a sufficient size and outputs the same through the speaker 112. In addition, the above-described microprocessor 100 controls the motor group 106 through the pulse width modulator 103, the buffer 104 and the motor driver 105 to operate according to the input voice command. An action on the voice command, for example, sitting, standing up, moving forward, going backward, shaking the head, dancing, changing the color of the eyes, saying hello, lifting a leg, etc. is performed (step S26).

Here, the robot is composed of a total of 18 joints, each of the four joints and neck joints of each leg, the joints of each leg is composed of a knee joint and a shoulder joint, the shoulder joint is 180 degrees forward, backward, the knee The joint can be rotated 180 degrees left and right. In addition, the neck joint can be rotated 180 degrees left and right, up and down.

In operation S12 and S13, if the voice command is not input or the security mode data is not input, the robot is controlled in the set free operation mode.

In other words, if a high frequency signal is received from the transmitter 200 and there is no voice command and security mode data in the high frequency signal, approximately one minute has elapsed and the free operation mode is determined. As described above, the pulse width modulator 103 In addition, the motor group 106 is controlled through the buffer unit 104 and the motor driving unit 105 to perform the movement operation and the movement reaction operation of the robot in the free operation mode.

The free motion is possible by various operation modes by the program, the free motion mode of the robot sit, stand up, go forward, go back, left turn, right turn, head shaking, left view, right view, leg lifting Performs an operation such as shaking the forelimbs, greetings, dancing to the gymnastics, and outputs a voice suitable for the situation through the voice generating means.

In addition, when the robot driven by the predetermined free operation mode and the voice command encounters an obstacle and a cliff or falls down to the left or the right side during the free operation, the robot returns and performs the same operation as in the security mode. The movement operation and movement response operation for the designated free operation mode and voice command are continued.

In this way, in order to stop the operation of the robot in the state where the robot is performing the movement operation corresponding to the voice command and the movement reaction operation or the set free operation mode, the switch 116 is turned off or the transmitting device ( When the voice stop command is input from the step 200 (step S28), the microprocessor 100 controls the motor group 106 to stop the free operation (step S24).

As another embodiment, as shown in FIG. 1, the first microphone 120 and the first voice recognition unit 102 are installed in the robot instead of the transmitter 200 so that the user inputs the voice at a short distance. You can control the robot. That is, when a voice is input through the first microphone 120 installed in the place of the robot, the first voice recognition unit 102 recognizes the voice signal input like the second voice recognition unit 207 and corresponds to the voice signal. This is possible by providing the code value to the microprocessor 100.

In addition, it is also possible to communicate with the dog-shaped robot by a high frequency transmission method using a serial communication with a computer.

On the other hand, as a comparative example, unlike the conventional technology, that is, when the robot toy performs only one predetermined operation continuously and repeatedly in place when the user's voice is input, the present invention provides the robot with the user's voice command. As a result, the robot generates a voice while moving or reacting to the movement. Also, the robot freely moves around the room to monitor outside intruders and make an alarm and call the designated phone number to perform a crime prevention function. .
