Abstract

A robot drive assembly (110) for moving a robot (100) along a substantially cylindrical pipeline within the pipeline, the assembly comprising first and second body portions (110A, 110B), the first body portion (110A) being arranged to be rotated about a longitudinal axis of the assembly relative to the second body portion (110B) by drive means (110M1), wherein the first body portion (110A) has at least one drive roller (111R) coupled thereto, the robot (100) being configured such that rotation of the first body portion relative to the pipeline and second body portion about a longitudinal axis of the first body portion causes the at least one drive roller (111R) to rotate in contact with an inner wall of the pipeline about a roller axis oriented such as to cause simultaneous rotation and translation of the first body portion (110A) with respect to the pipeline.
