The CIRCE Head: A Biomimetic Sonar System

The investigation of biomimetic perception is part of the broader research field of biorobotics which aims to investigate biological sensorimotor control systems by building robot models of them. The intent of bio-inspired engineering is to distil from the principles found in successful nature-tested mechanisms specific ”crucial functions” [1]. In addition to its interest for engineers, we believe that the CIRCE biomimetic sonar system, a robotic system which reproduces, at a functional level, the echolocation system of bats, is a unique experimental tool for biologists to systematically investigate how the world is not just perceived but actively explored by bats.
