The invention discloses a pipeline robot. A plurality of travelling mechanisms are arranged in the peripheral direction of a robot body and can retract or expand in the radial direction of the robot body. The traveling directions of the travelling mechanisms are parallel to the length direction of the robot body. A shoveling mechanism is arranged on the end surface of the robot body, can stretch and retract in the length direction of the robot body in a reciprocating manner and can rotate with the axis of the robot body as the axis. A first motor used for driving the shoveling mechanism to rotate and a hydraulic mechanism for enabling the shoveling mechanism to stretch and retract are arranged in the robot body. A processor is arranged on the robot body and electrically connected to a receiver, a controller matched with the receiver is a handpiece, and the travelling mechanisms, the hydraulic mechanism and the first motor are all electrically connected to the processor. The pipeline robot can travel in a pipeline, and can also be used for shoveling garbage in the pipeline.
