Course Description
Prof. Dr. Elmar Rueckert is teaching the course on Humanoid Robotics (RO5300) together with M.Sc. Nils Rottmann, who supervises the exercises. In this course he discusses the key components of one of the most complex autonomous systems. These topics are
- Kinematics, Dynamics & Simulation
- Representations of Skills & Imitation Learning
- Feedback Control, Priorities & Torque Control
- Planning & Cognitive Reasoning
- Reinforcement Learning & Policy Search

This course provides a unique overview over central topics in robotics. A particular focus is put in the dependencies and interaction among the components in the control loop illustrated in the image above. These interactions are discussed in the context of state of the art methods including dynamical systems movement primitives, gradient based policy search methods or probabilisitic inference for planning algorithms.
In sum, the lecture provides a structured and well motivated overview over modern techniques and tools which enable the students to define reward functions, implement robot controller and interaction software and to apply and extend state of the art reinforcement learning and planning approaches.
No special knowledge is required beforehand. All concepts and theories will be developed during the lectures or the tutorials.
The students will also experiment with state of the art machine learning methods and robotic simulation tools in accompanying exercises. Hands on tutorials on programming with Matlab and the simulation tool V-Rep complement the course content.

Grading
The course grades will be computed solely from submitted student reports of four assignments, for each you can get 25 points. Two weeks after the assignment presentation events, the reports and the code have to be submitted (one report per team) to hum_rob@rob.uni-luebeck.de. Below is the list of dates and deadlines. Please use Latex for submitting the assignments. A latex template can be found under https://drive.google.com/file/d/1sFo1qLH5Z9dX6Kdsg950UBCXCPiWOHng/view?usp=sharing
| Presentation Date | Topics | Points | Submission Deadline |

Bonus Points
You can receive up to 30 Bonus Points (BP) during the course, 10 BP during the lectures and 20 BP for submitting optional exercise solutions. To get BPs during the lecture, you have to successfully participate at the quizz sessions at the beginning of each lecture. To get BPs for the optional exercise solutions, you have to (clearly and readable) write down your solution, take a photo and send it to hum_rob@rob.uni-luebeck.de with the concern Exercise_##_LastName, where ## is the number of the exercise. You have to send your solution prior to the start of the exercise session where we will cover the exercise sheet.

Materials for the exercise
For simulating robot manipulation tasks we will use the simulator V-REP. For research and for teaching a free eduction version can be found here. To experiment with state of the art robot control and learning methods Mathworks’ MATLAB will be used. If you do not have it installed yet, please follow the instructions of our IT-Service Center.
Matlab Files shown during the Tutorial can be found here.
