“…Several recent studies were concentrated on robot manipulators or robotic machine tools for robotic grinding applications. A wheel-type in-pipe grinding robot, consisting of a moving structure, a positioning structure, and a grinding structure, was designed to grind girth weld beads for the circular boiler header on the inner walls of pipes [16]. An automatic portable three-axis orbital milling system was designed for removal of degraded dissimilar metal welds in piping systems of the nuclear power plants and preparation of the weld grooves of prescribed geometry for the repair welding [17].…”

“…2.1 Selecting Different Operations, Advantages,and Defects Pipe climber robots have different structure in movement mechanism. [11][12][13] This difference causes some merits and defects that have shown in Table 1. As it has shown in previous study, [7] the wheel pressed type has more advantages in comparison with other robot types.…”

“…Many researchers have tried to improve different aspects of using a robot to control its movement inside of the pipeline. Based on studies, [7,13,14] for designing of these type of robots, the robot structure, its operation and abilities should be noticed. More over some limitations such as size, shape, conformity, etc.…”

“…Ren, et al review the screw-type drives in piping robots and present their advantages, but the force analysis is not detailed. Some grinding piping robots have been developed [3,22]; however the design and analysis of drive units are not discussed in detail.…”
