Mini-Robotics-Projects

Mini Robotics Projects Collection

A curated repository of small-scale, hands-on robotics and mechatronics projects. This collection spans embedded systems, control algorithms, computer vision, and mechanical design, utilizing platforms like Arduino, ESP32, Raspberry Pi, and ROS2. 

📁 Repository Structure

Each project is self-contained within its own directory, including dedicated source code, circuit schematics, 3D printing models (STL), and simulation files.

🛠️ Global Prerequisites

Before deploying the code, ensure you have the following software environments configured: 

1. Embedded Toolchains

• Arduino IDE (v2.0+) or PlatformIO (Recommended)
• ESP32 Board Manager configuration for ESP-IDF/Arduino framework

2. Single Board Computer & Host Packages

• Python 3.10+
• OpenCV (pip install opencv-python)
• ROS2 Humble / Iron (Required only for advanced modules)

💻 Getting Started & Quick Deploy

To clone the repository and flash a specific project, execute the following commands in your terminal: 

bash

Clone the repository

git clone https://https://github.com/RoboticsengrRiyu/Mini-Robotics-Projects

Navigate to the workspace

cd mini-robotics-projects

Example: Open the obstacle avoidance project via PlatformIO CLI

cd 01_obstacle_avoidance pio run --target upload

Use code with caution.

For individual project configuration, hardware wiring diagrams, and specific library dependencies, please refer to the internal README.md file located inside each project's subfolder.
