Mastering ROS for Robotics Programming - Second Edition

By: Jonathan Cacace, Lentin Joseph

Overview of this book

In this day and age, robotics has been gaining a lot of traction in various industries where consistency and perfection matter. Automation is achieved via robotic applications and various platforms that support robotics. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book focuses on the most stable release of ROS (Kinetic Kame), discusses advanced concepts, and effectively teaches you programming using ROS. We begin with aninformative overview of the ROS framework, which will give you a clear idea of how ROS works. During the course of this book, you’ll learn to build models of complex robots, and simulate and interface the robot using the ROS MoveIt! motion planning library and ROS navigation stacks. Learn to leverage several ROS packages to embrace your robot models. After covering robot manipulation and navigation, you’ll get to grips with the interfacing I/O boards, sensors, and actuators of ROS. Vision sensors are a key component of robots, and an entire chapter is dedicated to the vision sensor and image elaboration, its interface in ROS and programming. You’ll also understand the hardware interface and simulation of complex robots to ROS and ROS Industrial. At the end of this book, you’ll discover the best practices to follow when programming using ROS.

Motion planning using the move_group C++ interface


In Chapter 6Using the ROS MoveIt! and Navigation Stack, we discussed how to interact with a robot arm, and how to plan its path using the MoveIt! RViz motion planning plugin. In this section, we will see how to program the robot motion using the move_group C++ APIs. Motion planning using RViz can also be done programmatically through the move_group C++ APIs.

The first step to start working with C++ APIs is to create another ROS package that has the MoveIt! packages as dependencies. You can get an existing seven_dof_arm_test package from the code provided with this book, or you can download it from the following repository:

$ git clone https://github.com/jocacace/seven_dof_arm_test.git

We can create this same package using the following command:

$ catkin_create_pkg seven_dof_arm_test catkin cmake_modules interactive_markers moveit_core moveit_ros_perception moveit_ros_planning_interface pluginlib roscpp std_msgs
