This paper compiles and analyzes some of the most current works related to upper limb prosthesis with emphasis on man-machine interfaces. A brief introduction of the basic subjects is given to explain what a prosthesis is, what types of prostheses exist, what they serve for, how they communicate with the user (control and feedback), and what technologies are involved. The method used in this review is also discussed, as well as the cataloging process and analysis of articles for the composition of this review. Each article is analyzed individually and its results are presented in a succinct way, in order to facilitate future research and serve as a source for professionals related to the area of prosthesis, such as doctors, engineers, researchers, and anyone interested in this subject. Finally, the needs and difficulties of the current prostheses, as well as the negative and positive points in the results are analyzed, and the progress achieved so far is discussed.
Maintenance of water resources through collection of water followed by laboratory analysis, is a key factor in the measurement of water quality. The main difficulty for water collection and analysis is the logistics of the process, since the collections are often made by mall boats in very distant aquifers, applying manual processes, and are sometimes based on few samples. In this paper, the development, construction, and implementation of a robotic airboat to measure water quality in lakes has been described. The airboat was developed in the form of a mini-boat, in a fiberglass structure, whose interior housed a battery, a Raspberry Pi mini-computer, a Wi-Fi router for connection to a notebook, tablet or cell phone, and sensors connected to the Arduino platform. The airboat was validated in two lagoons in Fortaleza, and in a reservoir in the city of Pacatuba. The results were collected with the purpose of analyzing the parameters of each lagoon. The main contribution of this work was the development of an autonomous system of acquiring water parameters from several points of the lagoon.
A Robótica Educacional (RE), que consiste no uso de robôs tendo em vista da proposição e do suporte ao processo de ensino e aprendizagem, tem assumido papel importante e se apresenta de forma recorrente em pesquisas nos últimos anos. Outrossim, num âmbito particular, a (RE) se apresenta como ferramenta também aplicável para o Ensino de Física, uma vez que nesse tipo de abordagem, os dados são adquiridos pelos próprios alunos, o que torna o estudo relativamente mais próximo dos estudantes. Neste trabalho, desenvolveu-se um conjunto de oficinas de RE para o ensino de Cinemática. Para a realização das oficinas foram utilizados Kits LEGO® MINDSTORMS®. Resultados mostram que dos 50% dos alunos que disseram não gostar de Física, 92,31% afirmaram que se sentiriam mais motivados para estudar Física com Robótica Educacional, além disso, 78,57% dos alunos respondeu que se sentiu mais interessado em ir para a escola por conta das oficinas de Física usando a Robótica Educacional, acrescente-se ainda o fato de que 96,43% dos alunos considerou que o uso de robôs melhorou a aprendizagem. Deste modo, os resultados mostram que a abordagem adotada contribuiu positivamente para o ensino de Cinemática, bem como na motivação para o estudo de física e participação ativa nas aulas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
