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

Creating URDF for an industrial robot


Creating the URDF file for an ordinary robot and industrial robot are the same, but in industrial robots, there are some standards that should be strictly followed during its URDF modeling, which are as follows:

  • Simplify the URDF design: The URDF file should be simple and readable and only need the important tags
  • Common design: Developing a common design formula for all industrial robots by various vendors
  • Modularizing URDF: The URDF needs to modularize using XACRO macros and it can be included in a large URDF file without much hassle.

The following points are the main difference in the URDF design followed by ROS-I.

  • Collision-Aware: The industrial robot IK planners are collision aware so the URDF should contain accurate collision 3D mesh for each link. Every link in the robot should export to STL or DAE with a proper coordinate system. The coordinate system which ROS-I is following are X-axis pointing forward and Z-axis pointing up when each joint is in...
