Boat (USV)

Overview

Our RobotX Boat, Crusader, features a catamaran configuration with a flat-bottom hull, which is ideally suited for calm and shallow-water navigation, thereby optimizing stability and maneuverability. With a focus on cost-effectiveness, ease to build, durability and proven construction method, we reused materials from previous competitions, including spare wood and high-density foam. Once we formed our foam hull, wood boards were added to the top and bottom for stiffness. Fiberglass was added with resin to strengthen the body. The boat is finished with paint to waterproof the hull(s) and aesthetic. Blue is the color of our team and the planet earth.
