EARLINET observations of the 14-22-may long-range dust transport event during SAMUM 2006: validation of results from dust transport modelling
2009
We observed a long-range transport event of mineral dust from North Africa to South Europe during the Saharan Mineral Dust Experiment (SAMUM) 2006. Geometrical and optical properties of that dust plume were determined with Sun photometer of the Aerosol Robotic Network (AERONET) and Raman lidar near the North African source region, and with Sun photometers of AERONET and lidars of the European Aerosol Research Lidar Network (EARLINET) in the far field in Europe. Extinction-to-backscatter ratios of the dust plume over Morocco and Southern Europe do not differ. Ångstr¨om exponents increase with distance from Morocco. We simulated the transport, and geometrical and optical properties of the dus…
Robotic path planning for non-destructive testing through RoboNDT
2015
The requirement to increase inspection speeds for non-destructive testing (NDT) is common to many manufacturers. The prevalence of complex curved surfaces in modern products provides motivation for the use of 6 axis robots in these inspections. The techniques and issues associated with conventional manual inspection techniques and automated systems for the inspection of large complex surfaces were reviewed. This paper presents a new MATLAB based software solution (RoboNDT), aiming to fulfil the requirements of robotized NDT inspection. RoboNDT enables flexible trajectory path planning to be accomplished for the inspection of complex curved surfaces. This newly developed software is capable …
Dinamiche della disuguaglianza e della robotizzazione: Un'analisi longitudinale
2022
Il crescente trend di automazione dei processi produttivi sta alimentando non poche preoccupazioni circa la possibilità che, in un futuro non troppo remoto, una quota rilevante di lavori tradizionali sarà rimpiazzata tout-court dai robot o dall’intelligenza artificiale, esacerbando, conseguentemente, le disuguaglianze. Con particolare riferimento all’impatto dei robot su svariati indicatori del mercato del lavoro, la letteratura empirica, attualmente, si è rivelata infruttuosa nel fornire risposte definitive ed esaustive, producendo evidenze contrastanti. Il presente contributo si inserisce nel dibattito in corso, proponendo un’indagine sulle dinamiche della robotizzazione e delle disparità…
Robots, labor markets, and universal basic income
2020
Automation is a big concern in modern societies in view of its widespread impact on many socioeconomic issues including income, jobs, and productivity. While previous studies have concentrated on determining the effects on jobs and salaries, our aim is to understand how automation affects productivity, and how some policies, such as taxes on robots or universal basic income, moderate or aggravate those effects. To this end, we have designed an experiment where workers make productive effort decisions, and managers can choose between workers and robots to do these tasks. In our baseline treatment, we measure the effort made by workers who may be replaced by robots, and also elicit firm repla…
Multi-aperture beamforming for automated large structure inspection using ultrasonic phased arrays
2019
Increasing the inspection quality and speed is essential in manufacturing applications, especially for large structures (e.g. modern aircrafts). Traditional ultrasonic manual scanning can be comprehensive, but lacks repeatability and is time-consuming. Several robotic non-destructive testing systems have been developed in recent years. Although high inspection rates have been achieved by the use of robotic arms, there is the need to furtherly increase the inspection speeds, to cope with the current industrial demands. For systems delivering robotic ultrasonic inspection through phased array probes, the current bottleneck is given by the time required to electrically fire all elements of the…
The influence of the cycloid disc bearing type on the cycloidal speed reducer efficiency
2021
The robotics industry has experienced a rapid expansion in the last decade. As a result, the market of speed reducers with high gear ratios, high precision and a compact design is growing rapidly. In addition to these characteristics, it is very important for gear trains to have high efficiency. Because of their compact design, cycloidal speed reducers are not exposed to axial forces, which is their important characteristic. This means that radial bearings can be used in their supports. The bearing type has significant effects not only on the design and dimensions of the cycloid speed reducer but also on its efficiency. In this paper, an analysis of power losses for different types of rolli…
Self-conscious robotic system design process-from analysis to implementation
2011
Developing robotic systems endowed with self-conscious capabilities means realizing complex sub-systems needing ad-hoc software engineering techniques for their modelling, analysis and implementation. In this chapter the whole process (from analysis to implementation) to model the development of self-conscious robotic systems is presented and the new created design process, PASSIC, supporting each part of it, is fully illustrated. © 2011 Springer Science+Business Media, LLC.
Exploiting Imperfections in Perception-Action Learning
2019
In this paper a some examples of simulations and experiments performed in the last few years in the field of bio-inspired robotics are reviewed and revisited, deepening their characteristics and emphasising the role of imperfections that could be the main actors guiding their success in real environment. Our cases of study rely on both geetic and behavioral experiments on the fruit fly, from which models, simulations and robotic experiments were performed.
Mathematical problem-solving in early school years with Bee-bot
2018
Los entornos relacionados con la robótica y los lenguajes visuales de programación por bloques permiten plantear tareas que pueden ser entendidas como problemas con contenido matemático aptos para edades escolares tempranas. Estos entornos permiten proponer situaciones problemáticas en edades en las que el formalismo o el escaso conocimiento matemático impide a los estudiantes abordar problemas matemáticos más complejos. En este trabajo se da cuenta de cómo el robot programable Bee-bot constituye un dispositivo privilegiado donde poder observar cómo los estudiantes toman decisiones durante el proceso de resolución. The environments related to robotics and the visual block-based programming …
