Abstract

This document reports the development of a Robot Nurse for Patient’s Lifting or Robot Enfermera para Carga de Pacientes (RECPA). This robot is designed for hospital use and is capable of assisting nursing personnel during the mobilization of patients. In the same way, it has a multimodal social interface that allows human-robot interaction in different modalities. The robot aims to be a support tool for nursing personnel, avoiding physical risks in their work environment. We target mainly to avoid back injuries, the most common work injury in nursing.The project was developed during 2017 and 2018 in collaboration with multiple partners (Hoiho, Fusmat, Mirai, Korella and Libersalus) under an agile project management method (SCRUM). The design and development have been supported by an in-depth analysis of the international and national robot markets. Similarly, a collection of qualitative and quantitative observations of hospital requirement and regulations was done. As a consequence, a high-resolution robot prototype is proposed to lift weight up to 70Kg.This report describes the technical advances of the project with a multidisciplinary approach; interaction design, multimodal interfaces, mechatronics, and social and service robotics for healthcare. Three main sections describe the multiple modules that conform the robot: the mechatronics section, the interface section and the product design. Each of these sections describes the design and development of 18 modules for user's control, positing of the robot and lifting weight. Initial sections describe the market study, definition of the needs, design proposals and early prototypes. Later chapters describe the construction of the robot, the development of the designs, redesign process, and modifications due to the limitations in equipment and manufacturing.RECPA presents several novelties in the successful integration of mechatronic devices and multimodal interactive technologies for the control of this service robot

Abstract

The optical, structural, and electrical characteristics of aluminum oxide thin films deposited by pulsed ultrasonic sprayed pyrolysis are reported. The films are deposited on crystalline silicon at temperatures from 400 to 550°C using a chemical solution of aluminum acetylacetonate, as source of aluminum, and N, N-dimethylformamide, as solvent. A H2O–NH4OH mist is supplied simultaneously during deposition to improve the films’ properties. The results showed that the properties of the as deposited films depended strongly on the number of pulses used and on the substrate temperature. The thickness of the films is under 300 Å and the best films’ properties showed an index of refraction close to 1.6 and a root mean square surface roughness of about 7.5 Å in average. Infrared spectroscopy shows that SiO2 is observed at the interface with silicon of the Al2O3 films and seemed to play, as expected, a dramatic role in the electrical characteristics of the interface. Films with a dielectric constant higher than 8 and an interface trap density at midgap in the 1010 eV-1 cm-2 range are obtained. Films deposited with three pulses and at 550 °C are able to stand an electric field up to 4 MV/cm. [ABSTRACT FROM AUTHOR]
