Change in Marker design/Testing

Difference between v1 and v2 marker designs: https://youtu.be/lEUagPaVh48

The redesigned marker dropper stays at the same place unlike the old marker dropper

We tested the difference marker designs by doing a controlled experiment around 6-7 times. We noticed that with the improved design (B), the marker stays exactly where it was dropped and does not move from its position. This means that after dropping the marker dropper, the marker will stay still. 

To-Do: Get the standard deviation of the tests

 The Arduino code of the marker dropper releases one marker at a time when “q” is pressed. Then, when you press “q” again, the marker dropper releases another marker below. We tested the marker dropper by setting up the Arduino and submerging the marker dropper in water.

To-Do: Add/integrate the code to “vscode” with CV to locate the Reefshark/sawfish

While doing the test, we noticed that because the marker dropper’s fins are larger and taller, the markers have an easier chance of escaping from the top dropper.

To-Do: We will extend the top of the marker dropper up so there is enough room and add a cap to the marker dropper so the markers can’t escape.
