Self-suucient and autonomous robots necessarily make their own decisions. As designers of robots we need ways of assessing their behaviour. A functional method, called the basic cycle which is based on the utility of the robot owner, is proposed to assess the robot's performance within an environmental niche. The method allows judgements to be made on the(More)
In this paper we consider three points. 1) Etho-logical behaviour models are not grounded in exhibited behaviour-the models have not been developed far enough, indeed, work in the ani-mat community may help ethology; 2) In order to assess agent performance we should try to develop a functional account of behaviour whilst developing a mechanistic account; 3)(More)
From Reactive Behaviour to Adaptive Behaviour Motivational models for behaviour in animals and robots E. H. Spier, Balliol College, Trinity Term 1997 A thesis submitted for the degree of Doctor of Philosophy This thesis presents one possible way to design a control architecture that can be used to govern arti cial animals. Such artefacts perform(More)
Object recognition is one of the most important tasks of the visual cortex. Even though it has been closely studied in the field of computer vision and neuroscience, the underlying processes in the visual cortex are not completely understood. A model that lately has gained attention is the HMAX model, which describes a feedforward hierarchical structure.(More)
In this paper we show that a phenomenon in animal learning theory (the outcome devaluation eeect) for which there is dispute over whether explicit representations and symbolic reasoning is required for its performance , does not require such things. This is done using a reactive motivational model, previously inspired from ethological thought, to which some(More)
My paper: Funda-Mentality: Is the conscious mind subtly linked to a basic level of the universe? Trends in Cognitive Sciences 2(4):119-127 (1998), was followed by an exchange focusing on the problem of free will (and other issues) between me and two critics, Emmet Spier from the Centre for Computational Neuroscience and Robotics, University of Sussex,(More)
