If you’ve worked with ROS and robots, there’s a good chance you’ve heard of gmapping, localization, SLAM, costmaps and paths. But what does all of this mean? They are more than just robot buzz words; they allow a robot to navigate from one point to another without bumping into obstacles. In our latest ROS 101 tutorial – ROS Navigation Basics – we’ll cover some of the key concepts in what makes up an autonomous robot, and walk you through a simulated example using Gazebo and Rviz.

The ROS 101: ROS Navigation Basics tutorial will show you how to:

  • Install ROS simulation, desktop and navigation packages
  • Launch a robot simulation in Gazebo
  • Build a map of a simulated world using gmapping
  • Visualize costmaps in Rviz
  • Localize a robot using the AMCL localization package
  • Simulate a fully-loaded Jackal UGV and view sensor inputs using Rviz

If you are new to ROS, it may be best to start your journey at the beginning with ROS 101: Getting Started With Ubuntu. For more tutorials, be sure to check out our Support Knowledge Base where you will find step-by-step guides for all Clearpath robots, as well as ROS, PR2 and Turtlebot.
