Overview of this book

Robot Operating System is one of the most widely used software frameworks for robotic research and for companies to model, simulate, and prototype robots. Applying your knowledge of ROS to actual robotics is much more difficult than people realize, but this title will give you what you need to create your own robotics in no time! This book is packed with over 14 ROS robotics projects that can be prototyped without requiring a lot of hardware. The book starts with an introduction of ROS and its installation procedure. After discussing the basics, you’ll be taken 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 ROS robotics applications for beginner, intermediate, and expert levels inside! This book will be the perfect companion for a robotics enthusiast who really wants to do something big in the field.

Interfacing the MPU-9250 with the Arduino and ROS


So the first step in this project is to interface the IMU to the Arduino to get the rotation values and send those values to ROS. We're essentially making an Arduino-ROS node that is receiving IMU values and publishing the yaw, pitch, and roll as well as the transformation (TF) corresponding to the IMU movement as ROS topics.

The following figure shows the interfacing of IMU with the Arduino. The IMU is interfaced using the I2C protocol:

Figure 7: Interfacing MPU 9250/9150/6050 with Arduino

The connection from Arduino to MPU-9250 is shown in this table:

To start working on IMU values in ROS, we have to create a ROS-Arduino node that is receiving IMU values and send it as ROS topics. I hope you have set up the Arduino IDE in your system. For running this code, you will need the Arduino library for the MPU - 9250. Note that you can use the MPU...
