Abstract
The present invention relates to an apparatus for performing nonmanual tasks on and adjacent vertical or nearly vertical surfaces. The apparatus is designed so that a portion of the apparatus can traverse the vertical or nearly vertical surfaces of structures which may include obstacles such as window frames or gaps created by window seams, without coming into physical contact with those surfaces. The apparatus includes a top control unit, a vehicle for traversing the vertical or near vertical surfaces, and a bottom control unit. The vehicle is maintained in a near constant spaced relationship to vertical or nearly vertical surfaces by elongated flexible members that connect the vehicle to the top control unit and bottom control unit.
