In order to strengthen our dedicated team in the Robotics Innovation Center (RIC) research department in Bremen we are looking for a
(full-time/part-time, 6 – 9 months)
The Robotics Innovation Center research department, headed by Prof. Dr. Dr. h.c. Kirchner, develop robot systems that are used for complex tasks on land, under water, in the air, and in space. The recently established underactuated lab at DFKI-RIC is looking for outstanding students to join us in pushing the boundaries of highly dynamic and agile robots.
Whole body control  has become the de-facto method of choice for the instantaneous control of highly redundant robotic systems like humanoids. On the other hand, whole body trajectory optimization has become a popular tool for discovering optimal trajectories for a variety of complex tasks we expect from humanoids. However, these trajectories might not be stable on a real robot. This master thesis explores the task of online stabilization of offline generated whole-body trajectories using QP based whole body control. The work will be applied to the simulation and control of RH5 humanoid .
Mathematical: Whole body control, Trajectory Optimization, Rigid body kinematics and dynamics, Linear Algebra.
Programming: C/C++, Python, experience with WBC frameworks, Model based optimization framework (e.g. drake, crocoddyl)
