Since Tesla released humanoid robot products, the field of robots will explode from time to time a hot spot, from the inevitable stage of technological development, the robot segment market is indeed promising, full of imagination. Therefore, in this issue, we will dismantle a very popular product in the pet monitoring market segment - pet monitoring robots.
The biggest difference between this pet monitoring robot named EBO and traditional surveillance cameras is that it gets rid of the limitations of fixed cameras and can be controlled and walked with mobile phone App, so it can basically meet the monitoring of the whole house without dead ends. So such an interesting product, wouldn't it be sorry for its advent if you don't disassemble and look at its hardware solution.
dismantle
The dismantling process is no longer shown in the text, and those who are interested can watch the video, mainly to see the overall structure and hardware scheme after dismantling.
First of all, the drive is a combination of two brushed motors + gear sets to achieve crawler movement, but it is really unreasonable to say that this price is not as brushless as the motor.
Then there are two Hall sensors on the interface board at the bottom to detect the backflush positioning of the robot battery, and another speaker is also connected to this small board. The microphone is placed at the top of the robot,But the sound recording effect of the call during actual use is not too ideal,You can refer to how the microphone circuit of some smart speakers is realized,You can know what's going on。
There is 1 1080P HD camera on the front of the robot, the pixels are not large, and there are two infrared LED lights next to it, which support infrared night vision function. Underneath the camera is a TOF sensor for TOF obstacle avoidance; The camera has two hollowed-out plastic sheets on top of it and LEDs underneath to indicate the status of the robot. The lithium battery used by the robot has a capacity of 2450mAh, which is provided by EVE. These are basically the internal structure and some components of this pet robot, and then focus on its motherboard.
In the middle is the core SoC of the pet monitoring robot, Xingchen Technology SSC333, based on the Arm Cortex-A7 processor, integrated image signal processor, video processor, encoder and other peripheral interfaces, mainly used for IP camera applications, to be honest, this SoC is used on the robot at this price, I think the performance is a bit stretched. Next to the SoC is Wuhan Xinxin's 16MB SPI NOR Flash, which is used to store the system firmware of the board. Aiwei Electronics' audio amplifier chip realizes the circuit of the microphone and the speaker. BGI Semiconductor's low-power MCU (HC32L130F8UA) is used to control functions such as motor drive of robots. Realtek's dual-band wireless WiFi chip (RTL8811CU) allows robots to connect to WiFi in the 2.4G or 5G bands. However, if you do not install WiFi in the whole house, it is not recommended to connect to the 5G frequency band, and there may be a robot that cannot come back after running out of the signal range. The chip surrounded by 4 inductors on the board is MPS's power management chip (MP5416), which integrates multiple buck converters and LDOs, with I2C interface and one-time programmability.
On the back of the board are some ports and MicroSD card holders. In addition, there is a charging management chip, although the specific model information has not been found, but it is speculated that it should be a domestic chip. In general, the BOM of this pet robot is still dominated by domestic chips.

brief summary
The above is basically the internal structure and hardware of this pet robot,Although it is called a pet robot,But in essence, it is still a variant of a security IP camera,It used to be said that women and children make money easily,Now I think I have to add pets,The premium of various electronic supporting peripheral products for pets is quite high。 However, on the other hand, it is not difficult to find that in fact, the current domestic hardware combination can fully realize various products in the field of not very high performance requirements, and the important thing is creativity. Just like the humanoid robot that is currently on fire, there is no doubt that with the continuous advent of various humanoid robot products, the final decision on the popularity and acceptance of the product may be a specific market segment, so which segment of the humanoid robot market are you most optimistic about in front of the screen?
