The quadcopter-based unmanned underwater and aerial vehicle has been designed. The vehicle electronics pressure casing has been designed and fabricated using acrylic material which can withstand an atmospheric pressure in aerial condition and external pressure of 10 bar in underwater condition to fly in both aerial and underwater conditions up to 100 m. This type of vehicle will be used in both civil and military applications for surveillance in the air and underwater conditions. Total payload of the quadcopter is 3 kg. The propeller assembly is tested to measure the maximum thrust force developed under bollard pull condition. The brushless DC motor and aerial fixed pitch propellers combination has been selected for the quadcopter type vehicle, and each motor is capable of producing a required thrust force for aerial as well as underwater condition. The flow analysis is carried out using water as the fluid medium for 3-knot speed, and drag force is found along the vertical direction is maximum. The developed quadcopter has been tested in underwater. The vehicle is found to be stable, and wireless control is working for about 1 m from the surface of the water.
