Patent ID: 7054717

Claim:
An end effector for a robotic arm for spraying a high-pressure fluid, said end effector comprising: a mounting bracket; a first nozzle having a head and a central axis, said nozzle being secured to said mounting bracket and positioned to align its said central axis in a direction of aim, said head being adapted to spray the fluid in a first spray along a first plane, said first plane including said central axis of said first nozzle, and said first spray having an effective cleaning region; a second nozzle having a head and a central axis, said nozzle being secured to mounting bracket and being positioned to align said central axis in said direction of aim, said central axis of said second nozzle being spaced apart from and substantially parallel to said central axis of said first nozzle, said head being adapted to spray the fluid in a second spray along a second plane, said second plane including said central axis of said second nozzle, and said second spray having an effective cleaning region; and, wherein said first and second sprays combine to form a spray pattern having a continuous effective cleaning zone, said sprays forming an area of overlap in said zone, said first and second planes being offset to space said sprays apart in said continuous effective cleaning zone, said sprays remaining apart in said area of overlap.
