Story

Idea

"Squid Game" is a very good TV series, and I like the game 321 Wooden Girl in the play. Considering my AI camera at hand can do human body recognition, I decided to reproduce the game 321 Wooden Girl. However, Shizuka, a female character in the play, can not only identify the human body but also judge the movement of the human body. The Shizuka I made only recognizes the human body. The usage process is like that, with the end of the countdown background music, Shizuka will look back to see if there is a human body within the target range. If a human body is found, the alarm will be issued, then keep turning back.

Hardware Connection

In this project 3 hardware would be used, including a Wio terminal, AI camera, and 9g steering engine. The connection method is quite simple and easy. The AI camera is connected to the grove port on the left side of the Wio terminal, and the 9g steering engine is connected to the grove port on the right side of the Wio terminal. After connecting to the hardware, power on with USB TYPE C to run the program. However, there is currently no burning program, and the later burning program and power supply can be realized through USB TYPE C.

Structural parts production

Considering it will be made of M3 wood later, I chose a 3mm thick wooden board in the process of building modeling.

Generate a plane-cutting drawing from the modeling, and then you can use this drawing to find a laser-cutting machine to cut the wood.

I drew Shizuka's avatar, printed it out with a color printer, cut out the outline, and stuck it on the AI camera. After sticking, I had to open a hole for Shizuka to leak out the position of the lens.

Assemble all the processed parts to get our 321 wooden girl. R3 nylon rivets, R2 screw studs, etc. are used in assembly here.
