BatSLAM 2.0: Sequence-Verified Sonar Place Recognition in a Robust Pose Graph

Echolocating bats can navigate dark and cluttered spaces using echolocation. Over a decade ago, BatSLAM showed that a robot with a biomimetic binaural sonar can build a topological map of the environment, by recognizing places from the received acoustic signals.

From the abstract. Our summary is in progress.
