story

I wanted to make a small AI Stack Chan, so I ported robo8080's AI Stack Chan to M5STACK ATOM S3.

*Stack Chan is a “cute” communication robot designed by Hashishikawa (@meganetaan/@stack_chan)

The synthesized voice uses VOICEBOX: Zundamon.

I broke many servo motors, re-arranged them many times, rebuilt the case many times, and got stuck in modifying the software, but with the help of pioneers, I finally completed it.

Is it Japanese culture to look for cuteness in robots? Even if it is not useful for labor, cuteness enriches people's hearts. I would like to continue to improve robots with the aim of creating robots that support people's minds.

I wanted a tiny AI robot. So, I built it based on robo8080's AI Stack-Chan and M5STACK ATOM S3.
