This weeks progress was made on both the NAVI website and hardware development. The “Weekly Meetings” pages for both the Senior Proposal and Senior Design sections were corrected after reverting to a default layout, restoring the intended design and formatting. Updates were also made to the monetary expenses section based on Dr. Ejaz’s feedback to ensure grammatical accuracy and clarity.
On the hardware side, the CAD model of the front plate was revised to include plate beds on both the top and bottom of the middle canted IR sensors, improving resistance against dust, humidity, and water exposure. Additionally, the IR sensor mount inlay was reinforced by increasing its thickness from 1.0mm to 2.0mm after testing revealed that the thinner version was prone to breaking during installation.
Key components including the motor driver, ADC multiplexer, and boost converter were received on Monday in the week, enabling the start of perfboard prototyping, soldering preparation, and the completion of soldering headers to said components. A perfboard was chosen based on dimensions as a possible solution to be fitted to the headset.
The CAD design phase has presented with ongoing challenges, particularly with geometry alignment, plane continuity, and complex surface modeling. To address these, new Fusion 360 tools such as the Loft, Rib, Offset, Split, Plane, and Sweep functions were explored and are being tested to finalize the headset’s frame and front plate. However, several issues persisted with curvature and continuity between the faceplate and front plate thus far, requiring the components to be sliced and separated for further refinement.
Thinking about future renditions, the coupling mechanism for the head strap will also need to be redesigned to properly integrate with the newly adjusted frame sections.
