Active Perception Lab Research methods

Accurate morphological models extracted from micro-CT images of real bat heads are used as input to acoustic simulation software to quantify the physical filtering that occurs during generation/reception of sounds. This methodology allows to reconstruct and study the spatial cues present in the echo signals as received by bats.

The novel sonar prototypes, both electronic and mechanical subsystem design and development is done in-house, are mounted onto commercially available robotic platforms (robot arms and mobile robots) and together with the tailored signal processing and robot controllers tested in real-world applications.

We have developed an information theory framework to quantify the information content of specific spatial cues extracted from the acoustic signals picked up by binaural hearing systems.
