A broad field of research topics are studied in the field of (i) bat bio sonar, (ii) robot sonar technology, (iii) human spatial hearing.
Bats (order Chiroptera) are one of the largest and most successful orders of mammals around the world. This success is partly explained by the exceptional perceptual system, i.e. bio sonar, bats use to get around in the dark. We study bat bio sonar (link naar CILIA) by building models, both conceptual, implemented as software simulations, and physical, implemented as elektromechanical replicas, models.
The intelligence and thus autonomy of robotic systems is to a large extent determined by their perceptual systems. Using a broad range of sensors guarantees autonomous operation in the broadest range of robot applications. We study how the insights gained from biosonar (link naar Chiroping) can be mapped onto high-performance robotic sonar systems. We develop novel sonar prototypes and integrate these prototypes into tailored robot control architectures that are designed to make optimal use of the information provided by the robotic sonar.
Human spatial hearing describes the capability of humans to localize sound sources in their environment. With the rise of virtual reality systems, the need for reproducing realistic auditory stimuli has grown proportionally. We apply the techniques we developed for studying how bats extract spatial information from the echoes returned by the environment to human spatial hearing.
