Abstract: A submersible robot for operating a tool relative to a surface of an underwater structure has a tool holder movably mounted on a support assembly provided with a driving arrangement for movably holding the tool in operative position relative to the surface. Position and orientation of the support assembly relative to the surface is locked and adjusted by locking and leveling arrangements. A programmable control unit operates the driving, locking and leveling arrangements and the tool and receives measurements from a sensor unit. The control unit has an operation mode wherein a positioning of the robot is determined and controlled as function of an initial position for defining a first work area, and shifted positions of the robot for defining additional work areas, the work areas having overlapping portions with one another for tracking displacements of the robot relative to the surface of the structure using the sensor unit.

Abstract: An apparatus for removing shingles and shingle fasteners from a roof. The apparatus comprises a frame and a driver unit coupled to the frame, the driver unit including at least one motor. The apparatus also comprises a stripping unit coupled to the frame. The stripping unit is adapted to lift shingles off from a roof and to extract shingle fasteners out of the roof as the apparatus moves on the roof. The apparatus further comprises a pair of cutters coupled to the driver unit, the driver unit being operative to drive the pair of cutters. The pair of cutters is adapted to cut shingles lifted off from the roof by the stripping unit to produce a strip of shingle material, the strip of shingle material including at least a portion of a first shingle connected to at least a portion of a second shingle by at least one shingle fastener extracted out of the roof by the stripping unit.

Abstract: An apparatus for removing shingles and shingle fasteners from a roof. The apparatus comprises a frame and a driver unit coupled to the frame, the driver unit including at least one motor. The apparatus also comprises a stripping unit coupled to the driver unit, the driver unit being operative to alternately move the stripping unit between two positions. The stripping unit is adapted to lift shingles off from a roof and to extract shingle fasteners out of the roof as the stripping unit alternately moves between the two positions and the apparatus moves on the roof. The apparatus further comprises a pair of cutters coupled to the driver unit, the driver unit being operative to drive the pair of cutters.
