6.2 Sea Markers

The competition course will mainly consist of floating buoys and a few cardinal marks. These elements are used to guide the ASVs through the course and to indicate the path they should follow. The teams' vessel must be equipped with sensors and navigation systems that can detect and interpret the markers, allowing the vessel to navigate around or through the obstacle.

Buoys:

The floating buoys will be of different colors, with each color indicating a specific instruction or direction for the ASVs. They will be placed strategically to define the course paths and objectives.

Cardinal marks:

Cardinal marks are used to indicate the cardinal directions (north, south, east, and west) and to provide a reference point for the ASVs. These marks will be placed at strategic locations along the course to help the ASVs navigate and stay on track.
