The exploitation of renewable marine energy sources requires devices which have been proven to be economically competitive with regard to other traditional energy sources. One of the current study aims is to reduce maintenance costs by successively automating more tasks. Since building real scale prototypes is too expensive and impractical, it is necessary to design and build laboratory prototypes in order to validate both the dynamic model and the control algorithms for the automatic emersion (depth to the sea surface) and immersion (from the sea surface to the depth of operation) maneuvers of hydrokinetic devices with which to harness renewable energies. This paper presents the instrumentation and control architecture of a reduced scale prototype that was conceived for experimentation in a calm water basin of up to 2 m in depth. It is based on a new modular actuator set together with a depth and a 3D-attitude sensor system connected by means of a NI-Crio embedded computer. The prototype of the proposed architecture allows us to validate different control systems by only reprogramming the respective control algorithms.
