For a long time, underwater robot has been used as a scientific research tool and a teaching platform, but the real application products have not been well explored. The successful case of UAV gives underwater robot a higher expectation. How to apply underwater robot and enter the market has become a hot spot of underwater robot research at present. This paper mainly introduces a bionic fish-shaped robot, redefines underwater robot with innovative thinking, determines product functions from the perspective of the market, and develops product functions and designs and realizes the structure of each part according to the existing scientific research experience. Main innovation points of this design are to adopt the way of the hybrid propulsion for underwater robot movement, through the form of a hybrid propulsion and long range and the contradiction between the rapid maneuver, at the same time of umbilical cord cable, using float design improvement, and through the highly integrated ground station for the system operation control.

Underwater Sites

In the last decade, the underwater activities performed by archaeologists and biologists have benefited from scientific research on the guidance, control, and sensory systems of unmanned vehicles. In fact, because underwater sites of interest are often difficult for divers to access, the use of unmanned vehicle technology to conduct surveys could be quite advantageous. In this paper, a novel and partially-biomimetic underwater robot, referred to as BRAVe (Biomimetic Research Autonomous Vehicle), is presented. For documentation purposes, it is equipped with a hybrid propulsion system, which consists of two different types of thrusters. The thrusters are designed to compensate for their reciprocal flaws in order to achieve a more efficient overall system. Specifically, the biomimetic thruster is employed for its superior energetic efficiency, and the horizontal propellers are exploited for accurate maneuvering. While the documentation and 3D reconstruction of the underwater seabed is a consolidated aspect for the authors, the hybrid propulsion system represents the main innovation of the present work. The increase in efficiency achieved by this propulsion system allows the vehicle to perform a thorough and precise documentation of underwater remains within short distances, while exploiting the maximum possible autonomy. This article discusses the details of the development of all the vehicle compartments and their associated characteristics, focusing on the significance of this technology. In addition, the results of 3D reconstructions extrapolated from images taken during real field missions are presented.
