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


In this chapter, we designed and built an autonomous mobile robot from scratch. The design of the robot started with its specification. From the specification, we designed various parameters of the robot, such as motor torque and speed. After finding out each parameter, we modeled the robot chassis and simulated it using ROS and Gazebo. After simulation, we saw how to create the actual hardware. We selected the components and interconnected the sensors and actuators to the embedded board. We wrote the firmware of the embedded board. The board can communicate with the PC on which the ROS is running. The ROS driver node receives the data from the robot and interfaces with the gmapping and AMCL packages to perform autonomous navigation.

In the next chapter, we will see how to create a self-driving car and interface to Robot Operating System.
