ABSTRACT:
Apparatus for positioning a probe carried by an elongated flexible carrier includes a cantilevered telescoping extensible boom. A sprocketed tractor feed mounted at the distal end of the boom engages apertures in the carrier for feeding it and deflecting it from the boom in a direction substantially perpendicular to the longitudinal axis thereof. The tractor feed is mounted for rotational movement about the longitudinal axis of the boom. A withdrawal device engages the carrier adjacent to the supported end of the boom for reeling the carrier up into a cartridge. Extension and retraction of the boom is effected by a rack and pinion mechanism. Rotary resolvers measure the movement of the boom, the movement of the carrier with respect to the boom and the rotary movement of the tractor feed for providing signals to an associated microcomputer, accurately to detect and control the position of the probe. The microcomputer additionally provides on-line visualization of sludge profilometry and topography.
