Robot Mapping - WS 2016/17

Robot Mapping

What is this lecture about?

The problem of learning maps is an important problem in mobile robotics. Models of the environment are needed for a series of applications such as transportation, cleaning, rescue, and various other service robotic tasks. Learning maps requires solutions to two tasks, mapping and localization. Mapping is the problem of integrating the information gathered with the robot's sensors into a given representation. It can intuitively be described by the question "What does the world look like?" Central aspects in mapping are the representation of the environment and the interpretation of sensor data. In contrast to this, localization is the problem of estimating the pose of the robot relative to a map. In other words, the robot has to answer the question "Where am I?" These two tasks cannot be solved independently of each other. Solving both problems jointly is often referred to as the simultaneous localization and mapping (SLAM) problem. There are several variants of the SLAM problem including passive and active approaches, topological and metric SLAM, feature-based vs. volumetric approaches, and may others.

The lecture will cover different topics and techniques in the context of environment modeling with mobile robots. We will cover techniques such as SLAM with the family of Kalman filters, information filters, and particle filters. We will furthermore investigate graph-based approaches, least-squares error minimization, techniques for place recognition and appearance-based mapping, and data association. The exercises and homework assignments will also cover practical hands-on experience with mapping techniques, as basic implementations will be part of the homework assignments.

Organization

  • Organizer: Wolfram Burgard
  • Tutor: Alexander Schaefer
  • Teaching is done in English.
  • This is an online lecture. That means students are responsible for studying the contents of the lecture and working on the assignments in a self-organized manner. Every week, the assignments are discussed during the exercise session.
  • Exercise sessions:
    • Date: on Thursdays, 15:00 to 16:30, starting on November 24
    • Location: SR 00 007, Georges-Köhler-Allee 106
  • Exam:
    • Type: oral
    • Dates: Monday, March 13, 2017, 9:00 AM to 2:00 PM, and Tuesday, March 14, 2017
  • There is a QnA forum for questions available.
  • Recordings, slides, homework assignments, and additional material is available on this website.
  • The lecture is part of the area Cognitive Technical Systems in the CS master program.
  • Teaching material and exercises are based on the previous course taught by Cyrill Stachniss
