Patent ID: 7291056

Claim:
A system for cleaning a glass surface of a surface light or a reflector comprising a truck mounted with a cleaning agent blaster, an articulated working robot including a blast nozzle and a CCD camera mounted on a front end of a manipulator, and an operating unit including an on-vehicle computer operable for recognizing dimensions from positional information based on an image of the cleaned object taken by the CCD camera and for collating the image shame of the object with a stored share so as to calculate positional information of the object, wherein an opening floor part which is freely open-close is provided in the vicinity of the center or the rear part of a load bed of the truck for lowering the blast nozzle mounted on the front end of the manipulator toward the object located on the ground and under the load bed in connection with instructions from the on-vehicle computer; and wherein a monitor displaying an image taken by the CCD camera for monitoring a cleaned object and a start/stop button for cleaning operation are provided near the driver's seat; so that after the blast nozzle is lowered, a cleaning agent is blasted from the blast nozzle mounted on the front end of the manipulator of the working robot toward the target object while measuring and determining the extent of cleaning based on brightness or light intensity of the cleaned object from an image taken by the CCD camera to perform and complete automatic cleaning, further comprising an extensible cornice for preventing dissipation of abrasives provided in such a manner to hang under the periphery of an opening floor part of the load bed of a truck so that the abrasive and its volatilized gas produced after cleaning do not leak outside, wherein the opening floor part is closed and the cornice is folded after cleaning so that the abrasive and its volatilized gas are sealed within an isolated room in a canopy on the load bed of the truck mounted with a working robot.
