Abstract
Robotic external pipeline crawler system employs the use of logic control to provide a system capable of constantly and accurately maintaining a position at the vertex of the pipe. This apex positioning can be maintained as it traverses the length of the pipe being inspected. This system is adaptable to both straight and curved pipe, multiple pipe diameters, and will substantially reduce set up time and vertical pipeline support crossing time. The crawler system also employs an advanced bracketry system which allows quick disconnecting and auxiliary powered movement allowing for decreased cycle time across pipe supports. The unique tire interface allows for additional surface area contact making extreme environmental conditions possible.
