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

Integrating ROS-VR application and Leap Motion teleoperation


In this section, we are going to replace the keyboard teleoperation with Leap Motion-based teleoperation. When we roll our hand to the anticlockwise direction, the robot also rotate anticlockwise, and vice versa. If we pitch our hand down, the robot will move forward, and if we pitch it up, it will move backward. So we can start the VR application and Turtlebot simulation like the previous section and, instead of keyboard teleop, run the Leap teleop node.

So before starting the Leap teleop node, launch the PC driver and ROS driver using the following commands:

$ sudo LeapControlPanel

Start the ROS driver using the following command:

$ roslaunch leap_motion sensor_sender.launch

Now launch Leap Motion on the Twist node using the following command:

$ rosrun vr_leap_teleop vr_leap_teleop.py

Now you can put the VR headset on your head and control the robot using your hand.
