Knowing Your Place in Real World Environments
The topic of mobile robot self-localisation is usually divided into the sub-problems of global localisation and position tracking. Both are now well understood individually, but few mobile robots can deal simultaneously with the two problems in large, complex environments. While eecient solutions have been found for metric maps, topological maps have, by nature of their compactness, the potenti...
متن کاملKnowing Your Place in the Real World
This paper addresses the scalability of existing techniques for mobile robot navigation to work in large, unstructured environments. In particular, we are interested in the problem of relocalisation after the robot has been placed at some arbitrary location (unknown to the robot) in a previously explored environment. In the rst instance, we assess the problems found when a system previously sho...
متن کاملKnowing loved ones' end-of-life health care wishes: Attachment
Objective—At times caregivers make life-and-death decisions for loved ones. Yet very little is known about the factors that make caregivers more or less accurate as surrogate decision makers for their loved ones. Previous research suggests that in low stress situations, individuals with high attachment-related anxiety are attentive to their relationship partners’ wishes and concerns, but get ov...
متن کاملKnowing one's place: a free-energy approach to pattern regulation
Understanding how organisms establish their form during embryogenesis and regeneration represents a major knowledge gap in biological pattern formation. It has been recently suggested that morphogenesis could be understood in terms of cellular information processing and the ability of cell groups to model shape. Here, we offer a proof of principle that self-assembly is an emergent property of c...
