    This work proposes the development of a low-cost ocean observation vehicle. This vehicle, a hybrid between Autonomous Underwater Vehicles (AUV) and Autonomous Surface Vehicles (ASV) moves on the surface of the sea and makes vertical immersions to obtain profiles of a water column according to a pre-established plan. Its design means production costs are low and efficiency is increased. Also, the vehicle is able to make high resolution space and time measurements simultaneously. GPS navigation allows the platform to move along the surface of the water while a radio-modem provides direct communication links and telemetry. The vehicle measures 1885mm by 320mm wide. It weighs 76kg. It navigates at a speed of 1.5m/s at 80% at full propulsion power and reaches a maximum depth of 20m. It is a vehicle of electrical propulsion with an autonomy of 3-5 hours. This work outlines the mechanical and electronic design of the vehicle, as well as considerations for navigational and immersion experiments.

    En este proyecto se desarrolla un vehículo de observación oceánica de bajo coste, híbrido entre los Autonomous Underwater Vehicles (AUV) y los Autonomous Surface Vehicles (ASV), esto es, que se traslada por la superficie del mar y realiza inmersiones verticales para la obtención de perfiles de la columna de agua de acuerdo con un plan previamente establecido. Estas dos características de la plataforma de observación propuesta, abaratan los costes de producción e incrementarían su eficiencia. El desplazamiento superficial de la plataforma permite la navegación mediante GPS y la comunicación directa y telemetría mediante radiomódem. Las dimensiones del vehículo son 1.885 mm de longitud y 320 de diámetro exterior, y posee un peso de 76 kg. En las pruebas de navegación alcanzó una velocidad de 1.5 m/s a un 80% de potencia de propulsion y una profundidad máxima de 20m. El vehículo posee una propulsión eléctrica con autonomía de 3-5 horas.
