Introduction to Mobile Robotics - SS 2021

Course content (engl.)

This course will introduce basic concepts and techniques used within the field of mobile robotics. We analyze the fundamental challenges for autonomous intelligent systems and present the state of the art solutions. Among other topics, we will discuss:
  • Kinematics
  • Sensors
  • Vehicle localization
  • Map building
  • SLAM
  • Path planning

Organization

Exercises

Each exercise session consists of two parts: a short recap of the lecture and the discussion of the exercise sheets.

Solving the exercise sheets is recommended but not mandatory to be admitted to the final exam. There are no bonus points.

Exercise sheets will be published about one week before the discussion session. We strongly encourage you to solve the exercise sheets beforehand to benefit from the discussions in class.

Send a mail to mobilerobotics@informatik.uni-freiburg.de for an appointment with one of the teaching assistants.
