<p>A remotely controllable travelling robot for operation inside a pipe or bore-hole has a tool mounting assembly (22) which is rotatable in support structure (14, 16) about a longitudinal axis. The support structure (14, 16) is mounted on a pair of skids (10, 12) by means of a hydraulically driven elevator mechanism including rams (32) mounted on the skids (10, 12) which lift the support structure (14, 16) to a required height so as to place the longitudinal axis approximately in coincidence with the axis of the pipe or bore-hole. A tool mounting head (80) forming part of the tool mounting assembly (22) is itself hydraulically powered for tilting about a transverse axis and for moving transversely relative to the longitudinal axis along a transverse bar (88) fixed in a tool mounting assembly casing (60).</p> |
