Promesses robotiques et liquidation du politique
2017
EnglishRobots are being feverishly promoted today to the detriment of human labor force, socio-environmental balance and politics. francaisSi les robots sont aujourd'hui promus de maniere frenetique, c’est au detriment de la force humaine de travail, de l'equilibre socio-ecologique et du politique.
An Agile methodology for Manufacturing Control Systems development
2007
Robotized manufacturing cells are required more and more often to process high variety of short life-cycle product. This increases the need for methods and techniques for easy reconfiguration of software programs running in Programmable Logic Controllers (PLC), i.e., devices able to control manufacturing systems. PLCs run embedded code characterized by a procedural nature that does not make it quite reconfigurable. In this paper we propose an AGIle COntrol System Development (AGICOSD) methodology that uses various practices of Agile software development methodologies and the Design By Contract (DBC) practice for modeling and programming manufacturing control systems. In this context we prop…
Selecting industrial robots for milling applications using AHP
2017
Abstract Industrial robots are usually used for pick-and-place applications, which require only point-to-point motion control. However, the recent developments, both in robot technology and in Computer Automated Machining (CAM) software, allow the use of these equipment in applications which require continuous path control, such as multi-axis milling processes. However, the producers do not offer robots specifically developed for this kind of application, thus the user has to choose the most appropriate robot for this goal from a wide range of general purpose robot types. This research work proposes a method based upon Analytic Hierarchy Process (AHP) for selecting the industrial robot for …
An architecture for automatic gesture analysis
2000
The field of human-computer interaction has been widely investigated in the last years, resulting in a variety of systems used in different application fields like virtual reality simulation environments, software user interfaces, and digital library systems.A very crucial part of all these systems is the input module which is devoted to recognize the human operator in terms of tracking and/or recognition of human face, arms position, hand gestures, and so on.In this work a software architecture is presented, for the automatic recognition of human arms poses. Our research has been carried on in the robotics framework. A mobile robot that has to find its path to the goal in a partially struc…
The Sound of Swarm. Auditory Description of Swarm Robotic Movements
2023
Movements of robots in a swarm can be mapped to sounds, highlighting the group behavior through the coordinated and simultaneous variations of musical parameters across time. The vice versa is also possible: sound parameters can be mapped to robotic motion parameters, giving instructions through sound. In this article, we first develop a theoretical framework to relate musical parameters such as pitch, timbre, loudness, and articulation (for each time) with robotic parameters such as position, identity, motor status, and sensor status. We propose a definition of musical spaces as Hilbert spaces, and musical paths between parameters as elements of bigroupoids, generalizing existing conceptio…
Considerations Concerning a Methodology for Musical Robotics and Human-Robot Interaction
2009
Robot technology is increasingly employed in artistic (musical) applications and as modeling tool for the investigation of general cognitive abilities and music related behavior in particular. Apart from the specifications of required system behavior and technological aspects of system design/implementation, problems occur concerning the evaluation of the systems. In recent approaches, techniques such as collecting informal reports, perceptual tests, video-based observational studies, or rating scales have been employed. Questions arise, however, as to the reliability and validity of these measures, and the lack of standardization diminishes the comparability of different studies. To attack…
A Neural Multi-Agent Architecture for an Autonomous Mobile Robot Control
1999
The aim of this paper is to introduce a multi-agent architecture for an autonomous robot control oriented to obtain high design modularity and high parallelism of decision processes. A multi-agent approach allows us to design several specialized agents and each of them is optimized in order to solve a single part of the whole task. Each agent is able to cooperate with other agent exchanging information, so the robot is able to make the appropriate policy of management to reach a prefixed goal. We tested the proposed architecture with a simple application: an autonomous mobile robot performs object retrieval tasks into unknown structured environments. The robot is not given a priori map of t…
Robots as intelligent assistants to face COVID-19 pandemic
2020
AbstractMotivationThe epidemic at the beginning of this year, due to a new virus in the coronavirus family, is causing many deaths and is bringing the world economy to its knees. Moreover, situations of this kind are historically cyclical. The symptoms and treatment of infected patients are, for better or worse even for new viruses, always the same: more or less severe flu symptoms, isolation and full hygiene. By now man has learned how to manage epidemic situations, but deaths and negative effects continue to occur. What about technology? What effect has the actual technological progress we have achieved? In this review, we wonder about the role of robotics in the fight against COVID. It p…
Texture analysis with statistical methods for wheat ear extraction
2007
In agronomic domain, the simplification of crop counting, necessary for yield prediction and agronomic studies, is an important project for technical institutes such as Arvalis. Although the main objective of our global project is to conceive a mobile robot for natural image acquisition directly in a field, Arvalis has proposed us first to detect by image processing the number of wheat ears in images before to count them, which will allow to obtain the first component of the yield. In this paper we compare different texture image segmentation techniques based on feature extraction by first and higher order statistical methods which have been applied on our images. The extracted features are…
