The support 1 includes fixed mount 11 and worm reducer 12.The fixed mount includes locking member 111 and support member
112, described one end of locking member 111 is fixedly connected on support member 112, and knob 113 is provided with its other end, passes through the rotation
The accommodating width at the two ends of locking member 111 can be adjusted for button 113.The rotating part of the support member 112 subtracts with the worm screw
Fast device 12 is co-axially located on the robot body 3.Worm reducer 12 described in the driving stepper motor of robot body, leads to
Crossing the rotation direction of the Pulse Width Control stepper motor of certain frequency just can realize the control to the angle of pitch of support 1, so as to
The harvester 2 for carrying robot body 3 conveniently adjusts different angles, is easy to control adjustment in use
Angle when harvester is shot or during screen display.
As shown in figure 4, being designed with collection on the general frame of the domestic robot system for the present invention, the harvester
Hold and be designed with receiving terminal application program on application program, the remote control, the domestic robot system can be realized
Monitoring remote video, the function of robot remote control.The realization of monitoring remote video function is to utilize collection terminal application program
To call the camera and microphone of harvester, and by its family's shooting to video, audio-frequency information passed by video
Defeated server transport is to long-range receiving terminal, i.e. client, and user is received by client application real time inspection
Video, audio.The realization of robot remote control function includes the angle of pitch control of motion planning and robot control, harvester camera
System and smart home Remote, corresponding control button is provided with client application, is pressed after control button, is controlled
System instruction by control device and instruction control server transport on harvester, then the communication such as the bluetooth for passing through harvester
The equipment of function is transferred to the controller of robot, and the controller of robot is by controlling two-phase DC MOTOR CONTROL robot
Motion conditions, then by controlling stepper motor to adjust the angle of pitch of harvester, while the communication module carried in robot
Interface can connect smart home, realize the intelligent electric appliance in remote control of domestic scene.This domestic robot system is on the one hand
Can be with more convenient, another aspect when controlling multiple smart homes, robot connects relay as Remote,
All signals all by this unique relay, are conveniently encrypted, add safety guarantee.
In addition, the present invention the domestic robot system based on mobile terminal using existing technology platform provide specialty,
Stable, quickly live access and distribution service, realizes remote audio video and checks, claps photo, video look back function and machine
People's mobile telecommunication control function.The SDK provided using cloud service is by video, audio medium stream plug-flow to cloud video server, cloud
A variety of live source access ways such as service support HLS/RTMP plug-flows can support million simultaneously there is provided the conversion of fast and reliable form
Send out live and watch, magnanimity CDN node is covered all around, the rigors of ultralow delay and the concurrent visit capacity of super large are met comprehensively.
