## What it is
Stack-chan is an open-source, JavaScript/TypeScript-driven desktop robot built on M5Stack (CoreS3) hardware, with firmware, MOD applications, browser-based development tools, cases, and schematics. It lets users flash firmware from a browser, run mini apps (MODs) on the device or in a simulator, and customize the robot without installing ESP-IDF or the Moddable SDK.

## Use cases
- build a cute AI desktop companion robot with M5Stack
- flash robot firmware from a browser without installing toolchains
- develop and install mini apps (MODs) for an ESP32 robot
- add ChatGPT-powered conversation to a desktop robot
- customize robot behavior with JavaScript or TypeScript
- 3D-print cases and assemble a robot from schematics

## When to choose
- you own an M5Stack device or M5StackChan and want a friendly AI robot
- you want to program embedded hardware in JavaScript/TypeScript instead of C
- you want browser-based flashing, simulators, and block-based coding for beginners
- you want open hardware designs (KiCad, Fusion360) to build or modify the robot

## When to avoid
- you need industrial or high-precision robotics
- you require non-ESP32 hardware platforms
- you want a fully assembled product with no tinkering and no firmware flashing
- you need long battery life or non-M5Stack microcontrollers
