Overview of this book

Robot Operating System (ROS) is one of the most popular robotics software frameworks in research and industry. It has various features for implementing different capabilities in a robot without implementing them from scratch. This book starts by showing you the fundamentals of ROS so you understand the basics of differential robots. Then, you'll learn about robot modeling and how to design and simulate it using ROS. Moving on, we'll design robot hardware and interfacing actuators. Then, you'll learn to configure and program depth sensors and LIDARs using ROS. Finally, you'll create a GUI for your robot using the Qt framework. By the end of this tutorial, you'll have a clear idea of how to integrate and assemble everything into a robot and how to bundle the software package.

Chapter 6, Interfacing Actuators and Sensors to the Robot Controller

  1. Switching circuit in order to control the speed of motors in a robot.
  2. A sensor that can detect the speed and direction of wheel rotation.
  3. In the 4X encoding scheme, we are extracting the maximum transition between the encoder pulses in order to get more counts from a single rotation.
  4. Using encoder count and distance per count, we can easily compute the displacement of the wheel.
  5. It is a smart actuator having a motor and a microcontroller that can be directly interfaced to a PC and used to customize different settings of the actuator. It can be connected as daisy chain manner, which is appropriate for robotic arm.
  6. It is the sensor for finding range and has one transmitter and one receiver. The transmitter transmits ultrasonic sound, and the receiver receives it. The delay between these process is used for distance...
