Maintenance
                                       Maintenance  robots  specially  designed  to  travel  through  pipes,
                                       sewers,  air  conditioning  ducts,  and  other  systems  can  assist  in
                                       assessment and repair. A video camera mounted on the robot can
                                       transmit video pictures back to an inspecting technician. Where
                                       there  is  damage,  the  technician  can  use  the  robot  to  facilitate
                                       small repairs quickly and efficiently.
                               Fire-fighting robots

                                       Better than a home fire extinguisher, how about a home fire-fighting
                                       robot? This robot will detect a fire anywhere in the house, travel to
                                       the location, and put out the fire.
                                       Fire-fighting robots are so attractive that there is an annual national
                                       fire-fighting robot competition open to all robotists. The Fire-Fighting
                                       Home Robot Contest is sponsored by Trinity College, the Connecticut
                                       Robotics Society, and a number of corporations. Typically  a  fire-
                                       fighting  robot  becomes  active  in  response  to  the  tone  from  a
                                       home fire alarm. During the competitions, its job is to navigate
                                       through a mock house and locate and extinguish the fire.
                               Medical robots
                                                                                                             9
                                       Medical robots fall into three general categories. The first category
                                       relates to diagnostic testing. In the spring of 1992, Neuromedical
                                       Systems, Inc., of Suffern, N.Y., released a product called Papnet.
                                       Papnet is a neural network tool that helps cytologists detect cervi-
                                       cal cancer quickly and more accurately.

                                       Laboratory analysis of pap smears is a manual task. A technician
                                       examines each smear under a microscope looking for a few abnor-
                                       mal cells among a larger population of normal cells. The abnormal
                                       cells are an indicator of a cancerous or precancerous condition,
                                       but many abnormal cells are missed due to human fatigue and
                                       habituation.
                                       Scientists have been trying to automate this checking process for 20
                                       years using computers with standard rule-based programming. This
                                       was not a successful approach. The difficulty is that the classic algo-
                                       rithms could not differentiate between the complex visual patterns
                                       of normal cells and those of abnormal cells.

                                       Papnet  uses  an  advanced  image  recognition  system  and  neural
                                       network.  The  network  selects  128  of  the  most  abnormal  cells
                                       found on a pap smear for later review by a cytologist.
