The visual inspection of hydraulic structures is an activity that usually requires trained human beings able to produce opinions about the items inspected. However, due to the diversity conditions, the inherent difficulties on sub aquatic works and the safety of the individuals involved in these inspections, this task becomes a complex management problem. Due to these facts and aiming to provide better conditions of work it was proposed the utilization of remote monitoring systems through different types of cameras and sensors. Motivated by these questions the project was elaborated and the prototype of a sub aquatic inspector vehicle was constructed that attempts mostly to permit the study of an effective and possible solution for the question “eliminate risks and supply better conditions of work”. The projected vehicle consists in a wired remote controlled mobile system that is capable to capture images and transmit them to a distant place through cable which permits the posterior storage and analysis. The vehicle developed to the tests was conceived with the initial objective to permit the basic formation of the knowledge. Therefore, this first prototype was focused on problems relatives to the capacity of floatation and maneuver, internal cooling systems and video monitoring systems. The project of the “Underwater Inspector Vehicle” was named “VSI-1”.
