ROS Robotics By Example

Overview of this book

The visionaries who created ROS developed a framework for robotics centered on the commonality of robotic systems and exploited this commonality in ROS to expedite the development of future robotic systems. From the fundamental concepts to advanced practical experience, this book will provide you with an incremental knowledge of the ROS framework, the backbone of the robotics evolution. ROS standardizes many layers of robotics functionality from low-level device drivers to process control to message passing to software package management. This book provides step-by-step examples of mobile, armed, and flying robots, describing the ROS implementation as the basic model for other robots of these types. By controlling these robots, whether in simulation or in reality, you will use ROS to drive, move, and fly robots using ROS control.

Chapter 6. Wobbling Robot Arms Using Joint Control

Mobile robots are good at getting from one location to another without running into things around them. To be even more useful, a robot arm can grasp and manipulate objects in its environment. This chapter features a leading-edge robot that uses its two arms to perform tasks from manufacturing to human assistance and more. The Baxter robot by Rethink Robotics is a collaborative robot that safely works alongside humans without the need for safety precautions. The authors thank Rethink Robotics for their recent open source release of Baxter Simulator so that the simulated version of Baxter could be included in this book for those who cannot afford to purchase a real Baxter.

In this chapter, you will be introduced to Baxter in both real and simulated form. The software for Baxter Simulator will be installed and executed to bring up the Gazebo environment with a Baxter model in it. Baxter's arms will be controlled using a variety of methods:...
