Much like drones in the air and robots on the ground, unmanned surface vehicles (USVs) operate via remote control in all types of water and position different sensors in three dimensional space to gather data or transport people or equipment while remaining buoyant.
The two propellers can drive the lifebuoy to maximum speed of 12km/h.The Dolphin 1 provides a buoyancy that is equivalent to 2 regular buoys, allowing it to carry two people at a time.The Dolphin 1 is bright orange and mounted with two high penetration flashing fog lights, making the buoy highly visible in over long distances and in bad weather.
