**Summary of Twisted-Fields/acorn-robot-electronics** • **Project Overview**: This GitHub repository contains PCB (Printed Circuit Board) hardware designs for Acorn, a precision farming rover developed by Twisted Fields. The project aims to create an open-source, affordable, and customizable platform for agricultural research and automation. • **Rover Specifications**: - **Size**: Acorn is designed to be compact, measuring approximately 40cm x 30cm x 20cm, making it suitable for navigating through rows of crops. - **Weight**: The rover weighs around 10 kg, including the battery, making it lightweight and easy to maneuver. - **Power**: It is powered by a 6-cell LiPo battery pack, providing enough juice for extended field operations. • **Hardware Components**: - **Main Controller**: The rover is controlled by an STM32F4 microcontroller, which is responsible for processing sensor data, controlling actuators, and managing communication. - **Navigation Sensors**: Acorn uses a combination of encoders, a magnetometer, and an ultrasonic sensor for navigation and obstacle avoidance. - **Communication**: It features an ESP32 module for Wi-Fi connectivity, allowing users to control the rover remotely or stream sensor data to a base station. • **PCB Designs**: - **Main Board (Acorn_v1.0)**: This board houses the main controller, sensor interfaces, and communication modules. It is designed using KiCAD EDA software. - **Motor Driver Board (MotorDriver_v1.0)**: This board controls the rover's four DC motors, providing independent speed and direction control for each wheel. - **Power Management Board (Power_v1.0)**: This board manages the battery charging, voltage regulation, and power distribution for the rover's components. • **Firmware and Software**: - **Firmware**: The rover's firmware is written in C and runs on ChibiOS/RT real-time operating system. It provides drivers for sensors, actuators, and communication modules. - **Software**: Twisted Fields provides a Python-based command-line interface (CLI) and a web-based user interface (UI) for controlling and monitoring the rover. • **Open-Source License**: The project is open-source, released under the GNU General Public License v3.0 (GPL-3.0), allowing users to study, modify, and distribute the hardware and software designs freely. • **Community and Support**: The project maintains an active community on GitHub, with contributors and users sharing their experiences, asking questions, and providing feedback. Twisted Fields also offers support through their website and social media channels. • **Why Saved**: This content was saved for its potential in agricultural automation and research. The open-source nature of the project allows for customization and collaboration, making it an interesting resource for both personal and academic projects in the field of precision farming.
