The SARS-CoV2 virus has spread world wide rapidly. Although a small fraction of the infected people need special care, this number is much greater than what the healthcare systems support. In the most severe cases, mechanical ventilation is crucial for patient recovery, but not available in the needed quantity. In Brazil, mechanical ventilators are mainly imported and at a high cost, increased by the pandemic and the economic crisis, and with high delivery delay, aggravated by the risk of infection of incoming ships, airplanes and external goods. In this sense, an emergency mechanical ventilator developed and produced in the country could save many lives due to the lack of mechanical ventilators. To address this issue, this paper describes the effort to develop such a device.
There are several proposals of robots for inspection of overhead power network, and most of them make use of UAVs (Unmanned Aerial Vehicle). Such proposals present disadvantages like, low controllability, small payload capability and short operation range. On this scenario, this work presents a robot that can move over the power line and has as features: three driven wheels, distributed control system and selfconfiguration frame. The robot can overpass all power line devices taking the advantage of its wheel's shape that provides a self-steering capability. The communications between each motor controller is done by IEEE 802.15.4 wireless communication standard. The robot can be controlled by an electrician to proceeds the inspection from the ground level or in an autonomous way. A prototype was constructed and was tested, in both, laboratory and field environment. The test results shown the effectiveness of the robot proposed.
O vrus SARS-Cov2 disseminou-se pelo mundo rapidamente. Embora uma pequena fração das pessoas infectadas necessitarem de cuidados especiais, este número é muito superior ao que o sistema de saúde suporta. Nos casos mais severos, a ventilação mecânica é crucial para a recuperação do paciente, e não está disponível na quantidade necessária. No Brasil, os ventiladores mecânicos são em grande parte importados a um custo alto, elevado pela pandemiae a crise econômica, e com um atraso grande na entrega, agravado pelo risco de infecção através de embarcações, aviões e bens vindos do exterior. Nesse sentido, um ventilador mecânico de emergência desenvolvido e produzido no país poderia salvar muitas vidas acometidas pela falta de ventilação mecânica. Para resolver esses problemas, este artigo descreve os esforços para o desenvolvimento de tal dispositivo.
