Steps towards intelligent robots by Ulrich Nehmzow( Book )

4 editions published in 1990 in English and held by 12 WorldCat member libraries worldwide

Abstract: "'Really Useful Robots', a research project in the domain of mobile robots, investigates new ways of controlling robots in order to achieve flexibility in unforeseen situations. This report describes the underlying ideas and mechanisms of that part of this research that has to do with competence generation. We propose a self-organizing type of controller for a mobile robot. Rather than decompose the control task into subtasks and implement these (an analytic approach) we propose to use competence generators which generate the necessary competences, using instincts (a synthetic approach). We have built a mobile robot and equipped it with a first version of such a self-organizing controller."
Mapbuilding using self-organising networks in "really useful robots" by Ulrich Nehmzow( Book )

3 editions published in 1990 in English and held by 11 WorldCat member libraries worldwide

Abstract: "The Really Useful Robots (RUR) project is seeking to understand how robots can be built that develop and maintain the task achieving competences they require for flexible and robust behaviour in variable and unforeseen situations, as opposed to these being installed by their designers. In this paper we present an experimental autonomous robot with a map building competence which uses a self-organising network. Map building forms a necessary step on the way to development of a navigational competence. Some encouraging initial test results are also presented."
Location recognition in a mobile robot using self-organising feature maps by Ulrich Nehmzow( Book )

2 editions published in 1991 in English and held by 11 WorldCat member libraries worldwide

Abstract: "Self-organising structures are a dominant feature of the experimental mobile robots built in our 'Really Useful Robots' project. This paper continues where [Nehmzow & Smithers 90] finished. It explains some initial experiments using self-organising feature maps, and how those maps can be used by a mobile robot to recognise locations in its environment. This location recognition capability is achieved without using sensory information. Instead information derived from the motor actions of the robot is used, and shown to be sufficient."
Using motor actions for location recognition by Ulrich Nehmzow( Book )

2 editions published in 1991 in English and held by 10 WorldCat member libraries worldwide

Abstract: "We present a Behaviour-based mobile robot that is able to autonomously build internal representations of its environment and use these for location recognition. This is done by a process of self organisation, no explicit world-model is given. The robot uses an artificial neural network for mapbuilding and additional adaptive processes to achieve successful location recognition. The robot reliably recognises locations in the world and can cope with the noise inherent to the real world."

Autonomous acquisition of sensor-motor couplings in robots by Ulrich Nehmzow( Book )

2 editions published in 1994 in English and held by 3 WorldCat member libraries worldwide

Abstract: "Fixed robot controllers are suitable for tasks whose main characteristics are known a priori. However, for tasks such as exploration of unknown territory, fixed controllers tend to be too brittle as they rely on predefined knowledge, supplied by the designer. For such tasks (i.e. tasks in which a-priori knowledge is limited) we propose to use self-organising controllers which allow the robot to acquire the necessary competences autonomously ([Nehmzow et al. 89]). The paper describes experiments with mobile robots, in which the robots autonomously determine effective connections between their sensory input and their motor response to it. In these experiments, artificial neural networks are used to store associations between sensory input and motor responses, the networks are trained in a self-supervised way, making use of so-called instinct-rules which govern the robots' behaviour. The fast learning achieved enables the robots to adapt to changing circumstances such as changes in their environment or their morphology (e.g. sensor failure)."

Experiments in competence acquisition for autonomous mobile robots by Ulrich Nehmzow( )

2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide

This thesis addresses the problem of intelligent control of autonomous mobile robots, particularly under circumstances unforeseen by the designer. As the range of applications for autonomous robots widens and increasingly includes operation in unknown environments (exploration) and tasks which are not clearly specifiable a priori (maintenance work), this question is becoming more and more important. It is argued that in order to achieve such flexibility in unforeseen situations it is necessary to equip a mobile robot with the ability to autonomously acquire the necessary task achieving competences, through interaction with the world. Using mobile robots equipped with self-organising, behaviour-based controllers,experiments in the autonomous acquisition of motor competences and navigational skills were conducted to investigate the viability of this approach. A controller architecture is presented that allows extremely fast acquisition of motor competence such as obstacle avoidance, wall and corridor following and deadend escape: these skills are obtained in less than five learning steps,performed in under one minute of real time. This is considerably faster than previous approaches. Because the effective wiring between sensors and actuators is determined autonomously by the robot, sensors and actuators may initially be wired up arbitrarily,which reduces the risk of human error during the setting up phase of the robot. For the first time it was demonstrated that robots also become able to autonomously recover from unforeseen situations such as changes in the robot's morphology, the environment or the task. Rule-based approaches to error recovery obviously cannot offer recovery from unforeseen errors,as error situations covered by such approaches have to be identified beforehand. A robust and fast map building architecture is presented that enables mobile robots to autonomously construct internal representations of their environment, using self-organising feature maps. After a short training time the robots are able to use these self-organising feature maps successfully for location recognition. For the first time the staged acquisition of multiple competences in mobile robots is presented. First obtaining fundamental motor competences such as wall following and deadend escape (primary skills), the robots use these in a second stage to learn higher levels of competence such as the navigational task of location recognition (secondary skills). Besides laying the foundation of autonomous, staged acquisition of high level competences, this approach has the interesting property of securely grounding secondary skills in the robot's own experience, as these secondary skills are defined in terms of the primary ones
