Lecture Material

||

Lecture CAB G11 Theory Quick examples on paper

Exercise HG G1 Real problems at robotic systems (e.g. ABB industrial arm) Matlab => bring along a laptop or join a colleague

Case Studies State of the art engineering and research at selected examples Not primarily relevant in exams (only some multiple choice questions)


Lecture Setup

||

If things are unclear, immediately interrupt and ask(I’m happy if the lecture becomes a discussion)

Write a mail or come to office hours if things need to be further explained We try to have a short recap of all important questions at the beginning of every lecture

Small exercises during lecture: Try to solve them without help of the solution! (it helps you to understand the difficulties)

Break between hours?
