Abstract: A remotely controlled unit providing three degrees of actuation (rotational, perpendicular to a long axis, parallel to a long axis) of a variety of attachments to assist in the inspection, measurement, lining, and repair of pipe lines. The degrees of actuation are accomplished using a hydraulic system having a hydraulic pump, reservoir, solenoid actuated automatic valves, pistons, and cylinders inside the body of the unit. The components are designed to operate in a partially to fully submersed environment. The unit has an on board camera system that allows an operator the ability to monitor the attachments. In addition to the degrees of actuation, the unit carries a hydraulic clamp that secures the robot in the pipe during its various operations. The unit is controlled and cameras viewed through a control cable that connects the unit to an above ground control station consisting of micro control boards controlled by a CPU.
