Research Interests: Whiskers in Nature and on a Robot.
Whiskers are a wide-spread touch sensor in many different animal species.
For example in rats they are almost as sensitive as our fingertips. Still they
haven't been studied much by engineers and roboticists.
Within the Artificial Mouse Project (AMouse)
we have built an artificial whisker sensor and mounted it on a mobile robot.
In collaboration with biologists, we are addressing questions about the somatosensory processing, the importance of the morphology of whisker on behaviors,
and what features of the system are essential for its amazing performance.
Thorough analysis of the sensory signals allows to identify the characteristics of this specific sensory modality. By integrating the perceptual model into a robotic agent, we can test the adequacy of our understanding.
