Bivalve burrowing robots: correlating shell morphology and movement pattern with burrowing efficiency


Germann, D; Schatz, W; Eggenberger Hotz, P (2010). Bivalve burrowing robots: correlating shell morphology and movement pattern with burrowing efficiency.

Abstract

This work examines correlations between functional morphology and behaviour in the instance of the burrowing locomotion of bivalves. A comparatively simple and assessable behaviour and a rich fossil record documenting the evolutionary adaptations in morphology make these animals adequate for investigation. In this paper a robotic setup to simulate the burrowing behaviour of bivalves is presented. Models of both natural bivalve shell shapes and artificially designed shapes are pulled into sediment in the rocking modality these animals typically use. Different shapes, motion patterns and a water expulsion mechanism are evaluated and compared in terms of burrowing performance. The results presented here and further experiments using the (improved) platform may shed light on how bivalves burrow, how features of functional morphology evolved and how efficient automatic burrowing devices may be constructed. Keywords: biorobotics, biomimetics, underwater robots, functional morphology, burrowing locomotion, shell morphology, bivalves, artificial evolution.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
