Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

3.2.1 Mapping theory

Course subject(s) Module 3. Autonomous Navigation

When you need to go somewhere, you will need some kind of map. But what kinds of maps are there? And which maps are most useful, in which situations?

Acknowledgment 

The mapping example used in the previous video (starting at 2:24), is inspired by the ROS-I Academy training. These trainings are designed by the ROS experts of FH Aachen and is part of the ROSIN project. Find more information about this training in the Additional Learning Module!

A map is mandatory for navigation. There are two ways to get a map:

  • Use a pre-existing map
  • Build by the robot itself (mapping process)

The mapping process is called SLAM: Simultaneous Localization And Mapping.

There are two main types of maps that are relevant in our case. Those are the topological maps and the metric maps.
