Mastering ROS for Robotics Programming

By: Lentin Joseph

Overview of this book

The area of robotics is gaining huge momentum among corporate people, researchers, hobbyists, and students. The major challenge in robotics is its controlling software. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book discusses the advanced concepts in robotics and how to program using ROS. It starts with 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. After discussing robot manipulation and navigation in robots, you will get to grips with the interfacing I/O boards, sensors, and actuators of ROS. One of the essential ingredients of robots are vision sensors, and an entire chapter is dedicated to the vision sensor, its interfacing in ROS, and its programming. You will discuss the hardware interfacing and simulation of complex robot to ROS and ROS Industrial (Package used for interfacing industrial robots). Finally, you will get to know the best practices to follow when programming using ROS.

Summary


In this chapter, we mainly covered interfacing a DIY autonomous mobile robot to ROS and navigation package. We saw an introduction of this robot and the necessary components and connection diagrams of the same. We saw the robot firmware and how to flash it into the real robot. After flashing the firmware, we learned how to interface it to ROS and saw the Python nodes for interfacing the LaunchPad controller in the robot and the nodes for converting twist message to motor velocities and encoder ticks to odom and tf.

After discussing the interconnection of the Chefbot nodes, we covered the C++ port of some important nodes for odometry calculation and the base controller node. After discussing these nodes, we saw detailed configurations of the ROS Navigation stack. We also did gmapping. AMCL and came into detail description of each options in RViz for working with Navigation stack. We also covered the obstacle avoidance using the Navigation stack and worked with Chefbot simulation. We...
