• Cardboard Flight Test #1

    After connecting the new version of the cardboard wings to the main body, it was time to perform some initial flight tests. Before making the trek to E7, some initial stability tests were performed in the hallway outside of our workspace. The first attempt was highly unstable, spinning backward very...


  • Debugging Custom IMU Boards

    Because the custom Atmel board uses an Atmega328PB, many libraries that work on the Arduino also work on the board. This simplified software development greatly as many chips, such as the selected BNO055 and BNO080 IMUs, already had libraries written for them. Two custom boards were soldered, one with each...


  • Testing Strategy - Custom vs Purchased Glider Body

    Building our own glider comes with certain timing challenges. There are 2 main components to the glider: the mechanical body and the glider electronics. Each has a design, development, and testing phase. Since certain electronic components depend on a working mechanical system for testing such as controls and system modeling,...


  • Arduino Prototype

    In order to expedite software development, we will be testing using an Arduino Prototype. Therefore, we can interface with sensors before moving to the custom PCB. Protoshield We will be using a Protoshield for our prototyping with the Arduino. Protoshields also allow us to: Keep cables organized Ensure components are...


  • Cardboard Airfoil Prototype #2

    The second airfoil was constructed using the heavier 24” x 48” 200 lb cardboard sheet. A 10” chord was chosen arbitrarily because this airfoil was only for experimental purposes to learn how to work with the material. Experiment 1: Scoring the Cardboard to Create a Curve The cardboard was still...


  • Cardboard Airfoil Prototype #1

    This airfoil prototype was created using construction guidelines from an RC plane hobbyist on Youtube, ExperimentalAirlines. He uses paper-covered foam from the Dollar Store to construct his airfoil. The YouTube video is included below. A constraint of the glider is to be biodegradable to limit the environmental impact of our...


  • PCB Design

    Overall board design It was decided to manufacture the boards at the University of Waterloo’s Rapid Prototype Center as this would allow for fast turnaround to debug and create new revisions quickly. To do this, the board would have to comply with the larger tolerances of the Center due to...


  • Foam-Ribbed Structural Prototype

    The first attempt at creating a rigid structure for the aircraft was started using craft foam-core, and wooden dowels. The cross section was a hand-cut approximation of the NACA 4418 airfoil. The body itself was modeled after an open-source 3D-printed flying wing structure. This featured both swept and tapered wings....


  • Existing Solutions, End-User Research and Criteria Development

    Humanitarian aid agencies often rely on ground transportation or airdrops to deliver humanitarian aid to remote locations. Within active combat zones, entering via the ground or air can be dangerous. During the Siege of Aleppo, research was done on other existing solutions which could be used to deliver humanitarian aid,...
