Motion planning is one of the most complex tasks in robot control. When computing the movements of a robot, it is not only required to take the mechanical parameters of the robot into account but also to pay attention to surrounding obstacles in order to avoid collisions. Thanks to new approaches like the Elastic Strip Framework developed by the research group of Prof. Oussama Khatib at Stanford University, these computations can be carried out in real-time and thus, the robot can also avoid moving obstacles. Especially in the field of human-robot interaction, one of the areas of research at the department of Prof. Alois Knoll at the Technical University of Munich, fast response to changes in the environment is important in order to ensure that humans do not get hurt by a collision with a robot. Findings from neurosciences suggest that another criterion might be of importance for motion planning in the context of human-robot interaction: The movements of a robot should be as natural and smooth as possible in order to appear sensible and predictable to humans. Thus, advanced mo-tion planners could play an important role in future scenarios for human-robot interaction. The main goal of the planned collaboration is to examine how the algorithms developed at Stanford University can be extended. The new methods will be evaluated on a KUKA lightweight robot.
