robo8080 (@robot8080) is known to be one of the biggest fans/longest involved contributors in the Stack-chan community since I released the M5Stack-Avatar library, the predecessor of the Stack-chan project.
He has been exploring the path of "cute robots" such as face customization and integration with various web services especially voice assistants for several years, The following are just a few examples of his diverse creations.
Alexa & Stack-chan
It responds to calls in conjunction with Alexa. It reports the weather forecast.
Google translate via Siri shortcut with Stack-chan
Using the Google Translate service via Siri's shortcut feature, making Stack Chan a great translation assistant.
Such as the applications above, he makes full use of the M5Stack's WiFi communication to connect to these services.
It's also worth noting that he uses cases among Stack-chan's assets, and uses the familiar M5Stack-Avatar library and other Arduino software stacks for firmware development.
He brings out the best of Stack-chan's capabilities in many ways, but what I found most iconic about his relationship with Stack-chan was the following tweet
Isn't this also a new and ideal relationship between robots and people?
