ABSTRACT:
An underwater robot is employed to clean and/or inspect the inner surfaces of high flow rate water inlet pipes for various facilities, such as power plants, water treatment plants, etc. The robot crawls along a cable positioned within a pipe to be inspected or cleaned, and in one embodiment, includes a plurality of guidance fins which rely upon the flow of water through the pipe to position the robot therein as desired. Retractable legs can also be provided to fix the robot at a location within the pipe when it is employed to clean the pipe using a water jet or similar system. The robot can also include a water driven turbine for generating electricity for the various motors, servos and other actuators contained on board the robot. Also, the robot preferably includes wheel or pulley arrangements which further help the robot to negotiate sharp corners or other obstructions within the pipe to be inspected or cleaned.
