Deliberative control components for eldercare robot team cooperation

Abstract

One important research area in autonomous mobile robotics is to create companions that live in our ambience and perform tasks to help in everyday life. On the other hand, Ambient Intelligence (AmI) seeks to create a network of helpful intelligent devices. This paper describes an approach for the development of cooperation models for eldercare robot teams using goal-driven control components. The framework and the approach are illustrated through the development and assessment of task allocation in multi-robot teams. Two cooperation models are implemented: (i) a team model based on the adaptive multiagent systems theory where task responsibility is agreed among team peers by exchanging individual estimations of the degree of difficulty and priority to achieve the task; (ii) a hierarchical model where a robot manager asks for the estimations of its team members and then assigns the task. Experimentation for team cooperation assessment is performed through considering environmental changes, as well as communications and internal failures. The proposal is simulated in an AmI-oriented elderly care center to assist seniors in need.

A Taxonomy of Vision Systems for Ground Mobile Robots

“…More complex approaches include locally weighted regression [35]. Lazy classifiers, despite being simple and having quite reasonable results for categorization tasks [12], present one important drawback: the large amount of data to be stored in memory (the complete training data sets) during the classification stage as well as the computational complexity associated with processing every training sample.…”

Design of Deliberative and Reactive Hybrid Control System for Autonomous Stuff-Delivery Robot Rover

“…Experimenting with decision-making models using a deliberative architecture requires the availability of engineering tools that enable rapid development, deployment, and evaluation (Ingrand, et al, 2017). Faced with various open environments and performing various tasks and interactions, autonomous robots require distinct considerations to complete their missions (Gascueña, et al, 2015). Further research in (Avram, et al, 2022) present a deliberative framework aimed at coordinating the automation of behavioral processes of robotic platforms intended for operation in harsh environments.…”
