A timeline is a visual representation of a chronological sequence of events in a story, process, or history. All teams have a story. And UFRJ's Nautilus could not be different. The stages since its creation, development and participation in events and competitions, made it possible to follow a unique trajectory. Immerse yourself in this story and discover details about each process we help to make.
Together they designed a first AUV model to participate in RoboSub, an international contest organized by RoboNation (an annual event in San Diego/United States, bringing together global teams to solve the proposed problems with AUV's). Called "Vovozão" the project was innovative and pioneering, with materials easily found, and low cost. Even simple, he was able to do image identification and data processing, using plates and sensors made by the students themselves. It contained 3 thrusters, and used flanges to ensure tightness. Due to problems related to transportation, there was no award.
UFRJ Nautilus was invited to speak at SEMEC (Mechanical Engineering Week).
In the period from 6 to 10 November 2017, UFRJ Nautilus offered a SolidWorks mini-course (3D CAD software) at SEng (Engineering Week version BETA), promoted by CaEng UFRJ (Academic Engineering Center) at the Federal University of Rio de Janeiro.
In March 2018, UFRJ Nautilus participated in the Nasa Science Day event, in Rio Design Barra, Rio de Janeiro/Brazil. An educational proposal by the Ancar Ivanhoe group bringing together NASA, the Brazilian Space Agency (AEB), the European Space Agency (ESA) and the Astronaut Foundation Ian Ramon - partner of the Israeli Space Agency (ISA). Accompanied by lectures, interactive workshops and exhibition of historical articles on aerospace memory, the team had a space for their AUV at the exhibition.
In May 2018, the team participated in the largest hacking, security and technology event in Latin America, the Roadsec.
After winning important company sponsorships, allowing the use of new platforms and materials, between July 30 and August 5, the team took Br-Hue to RoboSub. This time they managed to reach the semifinals, but due to tightness problems presented by the robot, there was no advance to the final.
In September, the captain of UFRJ Nautilus in 2018, Henrique Ferreira, represented the team speaking about the development of the same at the Oil & Gas TechWeek 2018. This event is organized by the Brazilian Institute of Oil and Gas.
UFRJ Nautilus was invited to speak about the team at ENAV 2018, the National Meeting of Naval Engineering Students, which took place from October 23 to 26, 2018. The theme of Enav 2018 was focused on the development of future professionals in the sector Naval and Offshore.
UFRJ Nautilus was invited to speak about the team and about SolidWorks (3D CAD software) at the 12th edition of Campus Party Brazil, between February 12th and 17th, 2019. This is one of the biggest events in technology, games, pop culture and entrepreneurship in the world. The event brought together about 900 speakers, among them Ivair Gontijo, a physicist and an engineer from NASA.
Again, but now in 2019, UFRJ Nautilus participated in the Nasa Science Day event, in Rio Design Barra, Rio de Janeiro/Brazil. An educational proposal by the Ancar Ivanhoe group bringing together NASA, the Brazilian Space Agency (AEB), the European Space Agency (ESA) and the Astronaut Foundation Ian Ramon - partner of the Israeli Space Agency (ISA). Accompanied by lectures, interactive workshops and exhibition of historical articles on aerospace memory, the team had a space for their AUV at the exhibition.
The year 2019 was dedicated to redoing the electronics of the robot that had been damaged, and ensuring the tightness of the Br-Hue. Participating for the third time in RoboSub, UFRJ Nautilus managed to reach the semifinal again.
Due to the excess of time employed by the University Hospital of the Federal University of Rio de Janeiro regarding the response time of the Covid-19 test to patients and their respective reports, making the process unfeasible, it was necessary to create a group called “Coorte”. In this group, UFRJ Nautilus developed a more autonomous and efficient method of sending emails to the Hospital.
An academic article (Paper) was published at Fusion 2020, by UFRJ Nautilus, about a faster way to compute the direction of a sound source (pinger) in relation to the robot through Beamforming more quickly (more than 10 times faster). This article is available on the IEEE website (for members).
UFRJ Nautilus performed at the launch of SOLIDWORKS 2020, at the convention center of Nova América, Rio de Janeiro / Brazil.
Due to the pandemic, the competition at 4 RoboSub had to take place remotely, focusing on the planning of the 3rd AUV. The team's technical report, website and a video produced by the members were evaluated. As a result, UFRJ Nautilus reached the 9th place in the competition, in addition to the “Holding Steady Award”, bringing financial value to the team.
In order to correct / update and improve accuracy, that is, the amount of correctness of the Beamforming (account made to verify the source of the pinger's sound and locate the robot) every 2 seconds of signal emission, a new Paper is being developed on a faster and more effective way to compute the direction of a sound source in relation to the robot more quickly (more than 10 times faster). This will be published in Fusion 2021.
