Meet the Keelcrab Sail One: an underwater drone designed specifically for hull inspection. It comes with 4 types of brushes (soft, medium,…), a high resolution camera, and a remote controller. The robot has a speed of 1.5 m2/minute and weighs 9.5kg.
Keelcrab simply needs to be put in a good position in the water to self direct to the hull of your boat. Its remote control device has a 7 inch display. Expected to ship in July.
