SwagRocket555 was designed to ace model rocket target altitude competitions. The goal was to deploy a speed brake based on the rocket dynamics to make a rocket stop at a specific altitude. The control board is a Teensy 3.6 shield, with a 3 axis gyro, a 3 axis low-g accelerometer, a 1 axis high-g accelerometer, a barometer, and a differential pressure sensor (for pitot tube). It actuates a servo (for extending the speed brake) and ignites a electric match (for deploying a chute).
We made a robot that autonomously solves a maze fast without prior knowledge about the walls. I made the robot hardware (PCB+chassis) and some motion control. My friends wrote the maze solver, state estimation, and a Gazebo simulator.
