Nowadays, the technological innovations affect all human activities; also the agriculture field heavily benefits of technologies as informatics, electronic, telecommunication, allowing huge improvements of productivity and resources exploitation. This manuscript presents an innovative low cost fertigation system for assisting the cultures by using dataprocessing electronic boards and wireless sensors...
This paper presents the research concerning the analysis of accelerometer data and the post-processing in order to monitor artistic and historical buildings. In particular, the case of interest was to consider the data acquired from a set of accelerometers suitably placed on the walls of a building, the “San Giacomo” structure, that is in renaissance style, built in 1663 and situated at the Old Town...
In this paper, the experimental application of a new class of optical pressure sensors based on polydimethylsiloxane (PDMS)-Au aimed at detecting and classifying millimetric surface damages of mechanical components is developed. The device consists of a tapered bended optical fiber, where an optical signal goes across, embedded into a PDMS–gold nanocomposite material (GNM). The sensor is automatically...
A new class of optical pressure sensors in a robot tactile sensing system based on PDMS (Polydimethylsiloxane) is presented. The sensor consists of a tapered optical fiber, where optical signal goes across, embedded into a PDMS-gold nanocomposite material. By applying different pressure forces onto the PDMS-based nanocomposite, changes of the optical transmittivity of the fiber can be detected in...
In this paper, the authors present a novel strategy applied to mechatronics device for reconstructing quite accurately smooth orthogonal-connected surfaces. The novel approach is based on the Fuzzy C-Means (FCM) classification and the RANdom SAmple Consensus (RANSAC) fitting. The system consists of four inexpensive ultrasonic sensors moved in the space by means of a controlled digital motor in order...
Future mobile robots will have to explore larger and larger areas, performing difficult tasks, while preserving, at the same time, their safety. This will primarily require advanced sensing and perception capabilities. In this respect, laser range sensors represent a feasible and promising solution that is rapidly gaining interest in the robotics community. This paper describes recent work of the...
