Martinez, H; Lungarella, M; Pfeifer, R (2010). On the influence of sensor morphology on eye motion coordination. In: 2010 IEEE 9th international conference on development and learning, University of Michigan, Ann Arbor, MI, USA, 18 August 2010 - 21 August 2010, 238-243.

Abstract

Developmental robotics focuses on how to endow robots with adaptive capabilities. Even though embodiment has been recognized as an essential factor for understanding development, there is yet not much work that investigates how the morphology of sensors and actuators shapes adaptivity and learning processes. Moreover, these studies are largely at an intuitive and qualitative level. In this paper, we address the issue by studying how in an active vision system sensor morphology and bodily features affect a behavior such as vergence. Specifically, we present an information-theoretic analysis of two experiments showing how adequate sensor morphology influences statistical dependencies in the sensorimotor loop. The results show that an appropriate morphology reduces the amount of input without disrupting the information structure in the sensorimotor loop. The second result shows how the later morphology under the vergence behavior increases the information structure among the motor actions and the pixels. We also speculate on the implications of our results for attention, reaching and grasping.

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.
