Cozmo ESP32

Abstract

1. Introduction

Um robozinho de bancada com rosto animado num OLED, que conversa por voz em português, controla o Mac e joga pedra-papel-tesoura.

Feito com um ESP32 de R$ 40 e peças de marketplace. O ESP32 cuida do corpo (rosto, luzes, som, braço, sensores) e o navegador do celular ou do Mac cuida da conversa, falando direto com a API de voz. Assim o ESP32 nunca precisa processar áudio.

entregues ao modelo como contexto. Ele não chuta números.

2. Objective

Robô de bancada com ESP32: rosto animado no OLED, conversa por voz em pt-BR, jogos e controle do Mac

This project demonstrates how C++, Arduino, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/fabriciowth/cozmo-esp32.git
cd cozmo-esp32

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
