Computer vision is used in Optical inspection systems, also known as automated optical inspection (AOI) systems, use cameras and image processing to identify defects in manufactured products. They are used in many industries to improve product quality, increase productivity, and reduce the need for rework.

Nodes send data over topics using messages. Publishers and subscribers must send and receive the same type of message to communicate.

Topics don’t have to only be one-to-one communication; they can be one-to-many, many-to-one, or many-to-many.

(

Topics are one of the main ways in which data is moved between nodes and therefore between different parts of the system.

ROS 2 breaks complex systems down into many modular nodes. Topics are a vital element of the ROS graph that act as a bus for nodes to exchange messages.

Each node in ROS should be responsible for a single, modular purpose, e.g. controlling the wheel motors or publishing the sensor data from a laser range-finder. Each node can send and receive data from other nodes via topics, services, actions, or parameters.

A full robotic system is comprised of many nodes working in concert. In ROS 2, a single executable (C++ program, Python program, etc.) can contain one or more nodes.

We take a look how to customize pen color and pen width of each turtle that generated by spawn service by rqt tool on ROS2.

Turtlesim is a lightweight simulator for learning ROS 2. It illustrates what ROS 2 does at the most basic level to give you an idea of what you will do with a real robot or a robot simulation later on.

The Robot Operating System (ROS) is a set of software libraries and tools for building robot applications. From drivers and state-of-the-art algorithms to powerful developer tools, ROS has the open source tools you need for your next robotics project.
