Aspirateur

Résumé

vignette|Aspirateur. Un aspirateur, aussi appelé balayeuse au Canada (les deux termes y sont employés indistinctement), est un appareil électroménager muni d’une pompe à air créant une dépression qui provoque l’aspiration de poussière et de petits déchets tombés au sol. Ce type d’outil sert au nettoyage des moquettes et des tapis, ainsi que des parquets, sols et autres surfaces. Trois technologies principales sont utilisées pour piéger la poussière : par passage dans un sac qui fait office de filtre primaire, par passage dans un collecteur démontable rigide à l’aide d’un système de séparation à cyclone, et par bullage dans de l'eau. Historique Les ancêtres des aspirateurs sont des balais à tapis. L'ancêtre direct de l'aspirateur était un balai à tapis inventé en 1860 par Daniel Hess. Il fonctionnait à l'aide de soufflets permettant de créer du vide. Le premier système de nettoyage utilisant le vide pour aspirer la poussière était manuel. Il s'agit du en, inventé à Chicago

A variety of reconfigurable surface devices, utilizing large numbers of actuated physical pixels to produce discretized 3D contours, have been developed for different purposes in research and industry. The difficulty of integrating many actuators in close configuration has limited the DoF and resolution and performance of existing devices. Utilizing vacuum power and soft material actuators, we have developed a soft reconfigurable surface (SRS) with multi-modal control and performance capabilities. The SRS is comprised of a square grid array of linear vacuum-powered soft pneumatic actuators (linear V-SPAs), built into plug-and-play modules which enable the arrangement, consolidation, and control of many DoF. In addition to the practical benefits of system integration, this architecture facilitates the construction of customized assemblies with an overall compact form factor. A series of experiments is performed to illustrate and validate the versatility of the SRS for achieving diverse tasks including force controlled modulation of interface pressure through integrated sensors, lateral manipulation of a variety of objects, static and dynamic shape and pattern generation for haptic interaction, and variable surface stiffness tuning. This SRS concept is scalable, space efficient and features diverse functional potential. This will extend the utility and accessibility of tangible robotic interfaces for future applications from industrial to home and personal use.

Modeling Vacuum Bellows Soft Pneumatic Actuators with Optimal Mechanical Performance

Wyatt Marshall Felt, Jamie Paik, Matthew Aaron Robertson

This paper presents the concept and model of "Vacuum Bellows," a cylindrical membrane-reinforced contractile vacuum soft pneumatic actuator (V-SPAs). These actuators consist of a tubular membrane connected to a series of interior rigid rings periodically spaced along its length. Our model shows how the rings can be spaced to achieve a desired actuator force profile. For example, the contraction ratio can be maximized by spacing the rings one diameter apart inside the tube. The work output of the actuator can be concentrated in the initial portion of the stroke by increasing the ring spacing. And, usefully, an approximately constant force-to-pressure relationship can be created by spacing the rings a fraction of a diameter apart. Our experimental results highlight the utility of the model and some practical considerations for actuator fabrication and use. The experimental results demonstrate how the ring spacing can be used to achieve high peak forces per unit pressure (three times greater than an equivalent-diameter piston achieved experimentally) or large contractions (achieved contraction to 30% of the extended length). Our model suggests that this performance can be improved with improved fabrication techniques.

Cutting Down the Energy Consumed by Domestic Robots: Insights from Robotic Vacuum Cleaners

Francesco Mondada, Philippe Rétornaz, Florian Christopher Vaussard

The market of domestic service robots, and especially vacuum cleaners, has kept growing during the past decade. According to the International Federation of Robotics, more than 1 million units were sold worldwide in 2010. Currently, there is no in-depth analysis of the energetic impact of the introduction of this technology on the mass market. This topic is of prime importance in our energy-dependant society. This study aims at identifying key technologies leading to the reduction of the energy consumption of a domestic mobile robot, by exploring the design space using technologies issued from the robotic research field, such as the various localization and navigation strategies. This approach is validated through an in-depth analysis of seven vacuum cleaning robots. These results are used to build a global assessment of the influential parameters. The major outcome is the assessment of the positive impact of both the ceiling-based visual localization and the laser-based localization approaches.
