"I found a mouse pad and wanted to match a computer."
This video was updated on Smart Jun's personal channel and Weibo. He said that "electronics" is a very interesting sideline project with low overall difficulty.
At the beginning of the video, he first introduced the motivation of the project, which is a story of "looking for a mouse pad and wanting to equip a computer". Zhi, who is keen on collecting all kinds of screens, got a round LCD screen this time. There are many projects that use this screen to make watches and pendants, and he turned his attention to the field of robots that he is interested in.
Zhihuijun said that there are many mini-robots, such as Toyota's dialogue robot "Kirobo Mini" and Sony's music egg "Rolly", but these products are too single in function, not extensible and open, and are limited by factors such as size. To achieve a slightly smarter interaction, you have to rely on mobile phone chips.
How to have a robot that needs no charging, is always on standby and has powerful computing power? Zhihuijun's idea is that by designing it as an accessory of a computer, you can get applications on the computer, have powerful computing power and connect to USB at any time.
The mechanical arm can be used as a "keyboard"
After making up his mind, Zhi started the project design.
The first is the hardware part. On the basis of the previous LCD screen, he expressed his "aesthetic online" and designed a robot with a round head and a round base with two arms by using curve modeling. As one of the main entrances of interaction, he hopes that the robot's mobile phone can rotate back and forth, left and right at the same time, so he designs a unique steering gear+gear structure in a limited space.
Subsequently, through a series of circuit, main control board and sensor design, the robot hardware has been completed, and then the software design, which is also called "the beginning of the positive film" by netizens.
If you only use "electronics" as a player, it is not much different from the previous small robots. To this end, Zhihuijun has developed a complete and multi-level open SDK.
"Electronic" gesture recognition
How does "electronics" work? He made a demonstration in the video. By adjusting the robot's right hand, the volume and brightness of the computer can be controlled, which can partly play the role of keyboard. In addition, the robot also has the function of AI algorithm to recognize gestures. "If there are two robots, not only can my face appear on the robot's screen, but he can also imitate my hand movements in real time." When Zhi talked about this function, netizens rated it as "true and digital twins".
At this point, he also mentioned the reason for naming. The robot is called "electron", and the computer connected behind it is the "brain" of the electron, referred to as "computer" for short.
"Electronic" can imitate the speaker's hand movements in the video.
Zhi Huijun said that the above functions are only a "superficial display". At the end of the video, he attached the open source address of software and hardware for everyone to develop again.
Zhi's last two paintings are a robotic arm that can sew grapes, and a self-driving bicycle that can go straight, turn and avoid obstacles. According to the data, Zhi 20 18 graduated from the University of Electronic Science and Technology of China, first joined the OPPO algorithm post, and then joined the "Huawei Talent Youth Program". Currently, he is an AI architect at Huawei. Before becoming Huawei's "genius boy", Zhizhi was already a famous UP owner in the science park.
At the end of this video, Zhi recalled the technical help post he posted on the forum when he was just getting started 10 years ago, and sighed: "Drinking ice for ten years is hard to cool your blood. Fortunately, the' rookie' ten years ago plunged into the desert like an ostrich, and then found that there was a sea of stars under the sand. "
