The audio acquisition unit is connected with the main control unit through the audio identification unit, and the other driving units, the video acquisition unit, the roadblock detection unit and the power management unit are all connected with the main control unit. The display screen and the loudspeaker on the trunk of the robot are directly connected with the main control unit. The camera of robot head connects the video acquisition unit, and infrared sensor lug connection main control unit, three microphone connection audio acquisition unit. The display screen and the loudspeaker on the robot trunk are directly connected with the main control unit, the power management unit is installed in the robot trunk, and the power management unit is connected with the solar cell panel. The driving wheel of the robot and the neck joint connecting the neck of the robot and the trunk of the robot are connected with the driving unit.
The roadblock detection unit is connected with the infrared sensor, and can quickly scan the surrounding environment through the infrared sensor, so that the route planning from the local place to the target place is realized.
The driving unit takes a single chip microcomputer AT89C51 as core hardware. The peripheral circuit, the motor driving circuit, the sensor detection circuit, the infrared remote control circuit and the like are coordinated to work under the control of the single chip microcomputer AT89C51, and the household intelligent robot is guaranteed to avoid obstacles in walking. The driving unit further comprises a first driving group for driving the head of the robot and a second driving group for driving the moving chassis of the robot, and the first driving group and the second driving group are respectively connected with the driving wheel and the neck joint.
The audio acquisition unit realizes acquisition of a voice signal through an SPCE061A chip system. The microphone adopts an electret capacitor microphone, and the electret capacitor microphone has the advantages of simple structure, high sensitivity, no directivity, small size and wide frequency response. The robot inputs the voice of an operator through a polar capacitance microphone, the voice resource is converted into a digital voice resource by an ADC (analog to digital converter) in an SPCE061A chip, the digital voice resource is put into a data queue, and the digital voice resource is compressed and encoded by an audio compression algorithm SACM _ S480 and then stored.
