摘要：A robot drive assembly 111B for moving a robot along a substantially cylindrical pipeline within the pipeline comprises a first body having a first axis arranged to be oriented, in use, substantially parallel to or coincident with a longitudinal axis of a pipeline; a motor drive 110M1 coupled to the first body; and a worm screw member 112WE coupled to the first body, the worm screw member 112WE carrying an external helical thread about a screw axis thereof, the motor drive 110M1 being arranged to cause rotation of the worm screw member 112WE about the screw axis relative to the first body; at least one drive wheel member 111R configured to engage an internal wall of the pipeline, the at least one drive wheel member 111R being arranged to be rotatably driven by the helical thread of the worm screw member 112WE to cause translation of the assembly within a pipeline.
