Abstract: Technical objective is to provide an in-pipe inspection robot for inspecting interior of a pipe, which can exert repulsive force to the pipe when the linear actuator is driven. To this purpose, the in-pipe inspection robot, which is moved inside the pipe to inspect the interior of the pipe, includes a linear actuator which is extendably and contractably driven, and a braking unit configured to fix a rear end of the linear actuator to an inner wall of the pipe and release a front end of the linear actuator from a fixed state, when the linear actuator is being extended, and release the rear end of the linear actuator from the fixed state and fix the front end of the linear actuator to the inner wall of the pipe, when the linear actuator is being contracted.
