<p>The purpose of the present invention is to provide an in-pipe robot for inspecting the inside of a pipe, which is capable of applying reactive force to the pipe when a linear actuator is driven. To this end, provides is an in-pipe robot for inspecting the inside of a pipe, which moves inside the pipe, comprises: a linear actuator which is driven to be extensible; and a braking unit which fixes a rear end of the linear actuator on an inner wall of the pipe while releasing a fixed front end of the linear actuator when the linear actuator is extended, and releases the fixed rear end of the linear actuator while fixing the front end of the linear actuator on the inner wall of the pipe when the linear actuator is contracted.</p> |
