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 10. Working with 3D Robot Modeling in ROS

The first phase of robot manufacturing is its design and modeling. We can design and model the robot using CAD tools such as AutoCAD, Solid Works, Blender, and so on. One of the main purposes of modeling robot is simulation.

The robotic simulation tool can check the critical flaws in the robot design and can confirm the working of the robot before it goes to the manufacturing phase.

The virtual robot model must have all the characteristics of real hardware, the shape of robot may or may not look like the actual robot but it must be an abstract, which has all the physical characteristics of the actual robot.

In this chapter, we are going to discuss the designing of two robots. One is a seven DOF ( Degrees of Freedom) manipulator and the other is a differential drive robot. In the upcoming chapters, we can see its simulation and how to build the real hardware and finally, it's interfacing to ROS.

If we are planning to create the 3D model of the...
