ABSTRACT:
A robotic vehicle is commanded by a fiber optic cable which also delivers television camera images. In the event the vehicle is moved backwards, the creation of a slack length of cable from a storage drum is avoided by the inclusion of a take-up reel in the vehicle. Any slack cable created by backward movement of the vehicle is immediately taken up by the take-up reel so as to prevent cable snags and possible damage by virtue of backward rolling of the vehicle over the cable. During normal forward operation of the vehicle, the take-up reel allows the cable to pass through it without interference.
