ROS Programming: Building Powerful Robots

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

Summary


This chapter was about vision sensors and its programming in ROS. We saw the interfacing packages to interface the cameras and 3D vision sensors such as vision_opencv and perception_pcl. We looked at each package and its functions on these stacks. We saw interfacing of basic webcam and processing image using ROS cv_bridge. After discussing cv_bridge, we looked at the interfacing of various 3D vision sensors and laser scanners with ROS. After interfacing, we learned how to process the data from these sensors using PCL library and ROS. At the end of the chapter, we understood how to stream a camera from an embedded device called Odroid to the PC. In the next chapter, we will see the interfacing of robotic hardware in ROS.
