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

Chapter 6. Manipulation with MoveIt!

MoveIt! is a set of tools for mobile manipulation in ROS. The main web page (http://moveit.ros.org) contains documentation, tutorials, and installation instructions as well as example demonstrations with several robotic arms (or robots) that use MoveIt! for manipulation tasks, such as grasping, picking and placing, or simple motion planning with inverse kinematics.

The library incorporates a fast inverse kinematics solver (as part of the motion planning primitives), state-of-the-art algorithms for manipulation, grasping 3D perception (usually in the form of point clouds), kinematics, control, and navigation. Apart from the backend, it provides an easy-to-use GUI to configure new robotic arms with the MoveIt! and RViz plugins to develop motion planning tasks in an intuitive way.

In this chapter, we will see how we can create a simple robotic arm in the URDF format and how we can define motion planning groups with the MoveIt! configuration tool. For a single...
