Abstract
An apparatusfor use oncomprising a vehicle adapted to move acrossa surface and responsive to an operator. A head assemblyconnected to a support on the vehicleis adapted to carry a device for engaging the surface. An actuatoron the vehicleraises and lowers thehead assemblysupportrelative to the surface. A position control responsive to operator input indicates aheadpositionof the device relative to the surface or range of head positionsof thedevicehead assemblyrelative to thesurfacesupport.The head position or the range of head positions indicates a distance or range of distances, respectively, between the device and the surface.A controller responsive to the position control selectively actuates the actuator or maintain thedevicehead assemblyin theheadpositionor within the range of head positions asindicated by the position control. As a result, a repeatable positionor range of positionsof thebrushheadassemblyis obtained, the relative engagement between the head assembly and surface is controlled and the treatment of the surface by the head assembly is controlled. Position control may be used in combination with torque control of motors driving brushes for engaging the surface. Position control may also be used in combination with a pressure control measuring the pressurebetweenofthebrushheadandassembly onthe surface.
