Hydroscorpion is a boat that takes the shape of a scorpion. The scorpion’s body is the main inspiration of our design process. It has a tail that extends out for balancing purpose. The motor is attached to a two-blade fan at the base and is powered by a 9-volt battery. The centre of the scorpion has a hollow space for placement of battery and wiring. Turrets are added to enhance its exterior look as we want our watercraft toy to be appealing to those who like tanks.
