ROS Programming: Building Powerful Robots

By: Anil Mahtani, Aaron Martinez, Enrique Fernandez Perdomo, Luis Sánchez, Lentin Joseph

Overview of this book

This learning path is designed to help you program and build your robots using open source ROS libraries and tools. We start with the installation and basic concepts, then continue with the more complex modules available in ROS, such as sensor and actuator integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, computer vision, perception in 3D with PCL, and more. We then discuss advanced concepts in robotics and how to program using ROS. You'll get a deep overview of the ROS framework, which will give you a clear idea of how ROS really works. During the course of the book, you will learn how to build models of complex robots, and simulate and interface the robot using the ROS MoveIt motion planning library and ROS navigation stacks. We'll go through great projects such as building a self-driving car, an autonomous mobile robot, and image recognition using deep learning and ROS. You can find beginner, intermediate, and expert ROS robotics applications inside! It includes content from the following Packt products: ? Effective Robotics Programming with ROS - Third Edition ? Mastering ROS for Robotics Programming ? ROS Robotics Projects

Getting started with AIML


AIML (Artificial Intelligence Markup Language) is an XML-based language to store segments of knowledge inside XML tags. AIML files help us store knowledge in a structured way so that we can easily access it whenever required.

AIML was developed by Richard Wallace and the free software community worldwide between 1995 and 2002. You may have heard about chatter bots such as Artificial Linguistic Internet Computer Entity (A.L.I.C.E.) and ELIZA. AIML is the base of these chatter bots. The dataset of the A.L.I.C.E. chatter bot is available under the GNU GPL license, and there are open source AIML interpreters available in C++, Python, Java, and Ruby. We can use these interpreters to feed our input to the knowledge base and retrieve the best possible reply from it.

AIML tags

There is a set of AIML tags to represent knowledge inside files. The following are some of the important tags and their uses:

  • <aiml>: Each AIML file starts with this tag and ends with the </aiml...
