![]() Note: This is valid on ROS 1 running on a Linux machineĢ. Setting Up the Infrastructure Software Setupġ. The ros_lib Arduino library enables the Arduino board to communicate with ROS. ![]() The Arduino ROS node publisher can send data (from sensors or robot state) from the board to the machine running ROS while an Arduino ROS node subscriber can get instructions from the machine. The rosserial ROS package uses Arduino’s universal asynchronous receiver/transmitter (UART) communication and converts the board to a ROS node that can publish ROS messages and subscribe to messages as well. This tutorial uses the publisher/subscriber paradigm to communicate between the Arduino board and ROS running on the machine. The ROS communication module operates on a customized TCPROS protocol within two paradigms: the many-to-many publisher-subscriber methodology, and the peer-to-peer faster services methodology. It includes any or all of motor control, temperature and ultrasonic sensors, IMUs and wheel encoders, and other devices. An Arduino controller mounted on a robot is used to perform the low-level/embedded control and sensing. ROS-based software frameworks run the high-level algorithms and processes like robot models’ inference, filtering, motion strategy generation, controller algorithms, and more. ![]() Arduino is mostly compatible with all digital and analog circuitry as well as external devices supporting serial communication interfaces like SPI, I2C, and UART. Probably the most used open-source microcontroller development board, Arduino offers an easy-to-use software-hardware interface and an ever-expanding user community. It is a language-agnostic platform with cross-platform communication support for different machines regardless of their site of deployment. ROS provides a standard communication architecture for seamless integration, use, development, and deployment of different components of a robotic system including control, perception, planning, and more. It is an open-source platform that helps makers and developers alike to get started with robotics software without reinventing the wheel. Robot Operating System (ROS) is one of the most popular and widely used robotics middleware software frameworks. This tutorial introduces a middleware software framework Robot Operating System (ROS) and walks you through the setup and use of ROS with Arduino to create more intelligent robotic systems. Often, as builders become more experienced, they look for robotics-specific software, as Arduino offers only part of the control. But with limited onboard computational power and software, often developers are unable to graduate to more complex robots. Arduino boards are used to build small robots and have simple logic defined control. ![]()
