Abstract: Provided herein is an active joint module, and a robot for inspecting pipelines having the active joint module, the active joint module including a frame unit; a first bracket connected to one side of the frame unit in a rotatable manner, and to which a first module is coupled; a second bracket connected to another side of the frame unit in a rotatable manner, and to which a second module is coupled; and a bracket rotating unit supported to the frame unit, and is configured to rotate the first bracket and second bracket independently from each other in response to receiving an operating signal, and to unconstrain rotation of the first bracket and second bracket in response to there being no operating signal received.

Abstract: Provided herein is a robot for inspection of a pipeline using a multi-output differential module, the robot including a robot body configured to move along an inside of the pipeline, and having a driving power supply unit; a proceeding unit rotatably-connected to the robot body, and provided with a plurality of active proceeding units having proceeding wheels that proceed along an inner wall of the pipeline; and a power transmission unit supported against the robot body, connected to the driving power supply unit to transmit driving power to the active proceeding unit, and having the multi-output differential module that distributes the transmitted driving power to the active proceeding unit.
