Dipl. Phys. Jan Hoffmann
I am a PhD student/Research Assistant
in the Department
of Artificial Intelligence (Prof. Hans-Dieter Burkhard)
at the Humboldt University in Berlin, Germany. My research
focuses on active vision and perception in mobile robots and
uses RoboCup as a test bed. Current work revolves around improving
Markov Localization (e.g. by proprioception and the use of
negative information) to allow the robot to actively reduce
uncertainty.
