ROS and MCUs

ROS (Robot Operating System) and Arduino can be used together in many robotic projects. ROS provides a high-level software platform and framework, while Arduino is a low-level microcontroller platform. By using the two together, it is possible to develop and control complex robotic systems.

Here are common scenarios where ROS and Arduino are used together:

1. Collecting Sensor Data: Arduino can be used to collect data from the physical world through various sensors (e.g. ultrasonic sensors, temperature sensors, light sensors). This data can then be transferred to ROS and processed.

2. Motor Control: Arduino can be used for motor control of wheeled robots or manipulators by using motor driver cards. ROS can send commands to control these engines.

3. Data Transfer: Arduino can use communication protocols such as serial communication (UART) or I2C to transfer sensor data or other information to ROS.

4. ROS Integration with Arduino: You can use a ROS package called "rosserial" to integrate Arduino with ROS. This package allows you to communicate between Arduino and ROS using serial communication.

These scenarios are typical use cases used in many robotics projects. The high-level programming and data processing capabilities provided by ROS, when combined with the low-level microcontroller capabilities of Arduino, can help your robots become more complex and intelligent. For this reason, various robotic projects can be developed by using ROS and Arduino together.
