Pre-requisites: In the previous tutorial, we learnt how to create our own ROS Package. This is the continuation of that tutorial, so if you haven’t gone through that, I’d suggest you to first read that.
In this tutorial, we will learn about the ROS Publisher- Subscriber Model in brief and then create our own Publisher Node and a Subscriber Node.
Message passing in…
In this article, we will discuss the following:
Make sure you follow the article and try the steps mentioned hands-on so that you can get a first hand experience.
Also, stay till the end because there is some bonus content I’ll be sharing with you all which will make your ROS package creation and build simpler!
Before we start creating and building our first ROS package, it is essential for us to understand what the catkin build system is.
catkin is the official…
Reinforcement Learning is a type of Machine Learning that uses dynamic programming to train algorithms to learn its environment and perform a specific task using a system of reward and punishment. A reinforcement learning algorithm, or agent, learns by interacting with its environment and taking actions for which it gets rewarded or punished.
Here, we’ll see the some of the basic terminologies that are used in Reinforcement Learning. All of these will be explained with the example of an Autonomous Car so that it becomes very easy for us to understand!
1. Agent: The entity (learning algorithm + policy) which interacts with the environment and takes certain actions to get the maximum rewards. Ex: An Autonomous Car.
2. Environment E: It is the surroundings through which the agent moves. The environment considers the action and the current state of the agent as the input and grants a reward for the agent and the…
Robot Operating System (ROS) is a flexible framework for writing robot software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms.
ROS was officially created and developed by Willow Garage starting from 2007.
ROS is currently maintained by Open Source Robotics Foundation
