TL;DR
Carlos3DPrint has created a real-life version of Linguo, the grammar robot from *The Simpsons*, using a combination of 3D printing, artificial intelligence, and a Raspberry Pi. This project is inspired by the character that Lisa builds for a school science fair, designed to listen to people and correct their language mistakes. Carlos aimed to replicate this functionality in a physical robot that can move, talk, and help improve English grammar.
