Embodiment Construction

[0028] see Figure 1-3 , the underwater environment robot system 10 includes an underwater robot 100 and a surface robot 200 . The underwater robot 100 is structurally configured such that it can dive below the water surface and perform various maintenance and inspection operations on underwater infrastructure. The surface robot 200 remains on the surface of the water and has its own propulsion system 202 so that it can move along the water surface in order to remain close to the underwater vehicle 100 . As the underwater vehicle 100 moves underwater, the surface robot 200 moves in a corresponding manner in order to maintain proximity to the underwater vehicle. Since the surface robot 200 moves to a position close to the underwater robot 100, the distance between the two robots is kept to a minimum. Thus, the distance for communicating through water between the surface robot 200 and the underwater robot 100 is minimized. It is very beneficial to minimize the communication d...

Abstract

A water environment robotic system that includes a control station, an underwater robotic vehicle, and a water-surface robotic vehicle. The underwater robotic vehicle is in communication with the water-surface robotic vehicle and the water-surface robotic vehicle is in communication with the control station. Accordingly, the water-surface robotic vehicle can act as a relay between the control station and the underwater robotic vehicle. The water- surface robotic vehicle is further capable of detecting the position of the underwater vehicle and automatically adjusting the position of the underwater vehicle in order to maintain general vertical alignment between the two vehicles.

Description

technical field [0001] Systems, methods and apparatus are provided for performing inspections of underwater assets, including pipelines and structures, including underwater and surface robots. Background technique [0002] Mobile robots can play an integral role in the inspection process of industrial infrastructure, including infrastructure in underwater and marine environments. Typically, to inspect underwater infrastructure, such as underwater pipelines, human submersibles or remotely operated vehicles are required. However, using submersibles poses safety concerns and is expensive. Remotely operated vehicles eliminate many of the safety concerns associated with submersibles, but these vehicles require a support vessel to store, activate and provide a platform for a human operator to control the vehicle. Such support vessels have a relatively large profile and require a minimum water depth for safe operation. Thus, it is difficult to inspect infrastructure located in s...
