This week was prototype inspection week. In preparation for the presentation, the team updated the live system: added new visualizations for pin classification, cleaned up the pin maps so they can be used during the presentation as an visual aid, and added a histogram display for plug classification so it is easier to see why a particular plug was chosen.

The team chose 7 plugs out of the 15 plugs in total to present. Of the 7 plugs, plug 15 was a base case to demonstrate the capability of the system, as it was easy to identify with few pins. Plug 1 and 14 were visually similar to each other, so they were chosen to demonstrate the capability of the plug classification system. The remaining 4 plugs were chosen to demonstrate particular edge cases of the pin classification system: plug 16 was a male plug, plug 12 was too large for the camera, plug 8 had a tall shell, and plug 6 allowed the probe to be inserted too deeply into the pin holes.

After the presentation, the team received overall positive feedback regarding their progress. In particular, the feedbacks focused on improving the readability of the visual display, and have a more comprehensive explanation for the purpose of the project as well as the testing plan.
