    Construção de um mini foguete
    Oct 2016 - Dec 2016 (3 months)
    Como alunos do 3º ano de Engenharia da Computação, tivemos que projetar e construir um minifoguete para participar da SpaceCup, competição organizada pela FIAP onde o objetivo principal é lançar o foguete de forma que ele caia sobre um alvo a 60m de distância. As peças do foguete foram construídas em uma impressora 3D. Um altímetro feito por nós também foi instalado na ogiva para medir a altitude máxima que o foguete poderia atingir durante o lançamento.

    Autonomous Robot Project for CyberCup
    Mar 2014 - Oct 2014 (8 months)
    The project is about the planning, design, construction, testing of an autonomous robot using an Arduino microcontroller, where the objective is to make the robot find the exit of a maze without the intervention of human control, only using sensors for the detection of obstacles. This robot is participating in a competition called CyberCup, promoted by FIAP, where all groups from all computer engineering classes face each other to determine which robot can get out of the maze in the shortest time possible. In addition to the Arduino, the robot did not have any ready-made construction "kit", that is, it was built with parts found on the market, so our group evaluated which components we should purchase, which led us to import the parts from
