ROS Robotics Projects

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.

Preface

Visualizing Leap Motion data in Rviz


We can visualize Leap Motion data in Rviz too. There is a ROS package called leap_client (https://github.com/qboticslabs/leap_client). You can install this package by setting the following environment variable in .bashrc:

export LEAPSDK=$LEAPSDK:$HOME/LeapSDK

Note that, when we add new variables in .bashrc, you may need to open new Terminal or type bash in the existing Terminal.

Now, we can clone the code in a ROS workspace and build the package using catkin_make.

Let's play around with this package. To launch nodes, we have to start LeapControlPanel:

$ sudo LeapControlPanel

Then start the ROS Leap driver launch file:

$ roslaunch leap_motion sensor_sender.launch

Now launch the leap_client launch file to start the visualization nodes. This node will subscribe to the leap_motion driver and convert it into visualization markers in Rviz.

$ roslaunch leap_client leap_client.launch

Now, you can open Rviz using the following command and select the leap_client...
