With the social progress and development, peoples material and spiritual improvement of the quality of the urgent need to clean from the heavy work out. Thus the birth of a service-oriented home cleaning robots, mobile robots will be cleaning technology and the organic integration of technology to achieve the family hotels, office buildings and other indoor environment clean and semi-automatic or fully automatic, 35so has a broad market prospects. In this paper, cleaning robots, on the domestic and foreign research and its key technologies are introduced, and the development of cleaning robots in the near future a number of issues were discussed.2 Cleaning robot research at home and abroadIn Europe America and Japan and Other developed countries, the development of cleaning robots earlier, is also a wider range of applications, the last two years, has developed a wide range of market-oriented intelligent cleaning robot.2.1 Japan produced vacuum cleanerJapan some company to promote the family in 2002 to use vacuum cleaner robots trial seize the opportunity 1 in the first half of the year. This robot may when according to the room shape the floor condition, the quantity of refuse carries on the automatic cleaning the work, first along the room all around will walk a memory room shape, then, while avoids the obstacle by vertical, the crosswise way back and forth to move carries on cleanly after the clearing completes, the automatic stopping This vacuum cleaner robot equipment has 50 sensors, but on the other hand on the one hand walks automatically carries on the cleaning. It uses the light and the ultrasonic wave range sensor, the feeling presses the sensor to avoid the obstacle; Built-in has the rotation sensor, uses for to control walks the posture maintains decides marches forward the direction; Has installed the rudder sensor, may examine marches forward the direction error which produces as a result of the rug pattern influence, even if therefore, in the shop has on rugs floor also to be able the straight line advance. In addition, this robot in vivo also installs has prevents heat source and so on dropping variance sensor which, sensation warming stove from high place and so on. Stair rolls down thermal seniors, to examine own receives the external force size definite weight sensor and the skid resistant sensor, the examination increase power load sensor. It may most little maintain with the ordinary obstacle 10 cm the distances but when surveys the heat source, will handle jointly with the heat source will maintain at least 50 cm the distances. Its contour size for wide 292 mm, long 367 mm, high 265 mm, heavy 9.8 kg, the maximum traveling speed is 30 cm/s. When the sensor survey on floors trash, will enhance the suction to usual15 times, simultaneously the traveling speed drop will be 15 cm/s, will carry on the cleaning carefully. Will not be having trash place by the 30cm/s speed migration the suction also 1O reduce, a charge may work 55 min will sweep clear 80 m2 the rooms, will vacuum the power is 90W.2.2 Australias V4 vacuums robotAustralia some company also to develop may go automatically and clean the room the V4 robot. This kind of completely automatic vacuum cleaner surface is smooth, the volume is very small, assumes the circular, the built-in acquisition radar, may search in each kind of room each, will not 36collide the furniture or other obstacles. Micro processes the small computer to cause it have is turning to roof pinnacle place can survey the direction, choice route of advances ability. So long as place the completely automatic vacuum cleaner in the ground, it then may start to work automatically. Its acquisition radar can surveys away from the recent wall, is being suitable the first wall attracts floor dust the foreign matter all around; Then back and forth moves anomalous again in room other positions, and can before the close obstacle changes rapidly. Should vacuum the robot, because 360has provided the obstacle sensor in main engines periphery, therefore may cleans the ground during the examination wall and obstacle; After cleaning the place which may go, robot on automatic shut-off power source. No matter the room contour and the area size, theARNA guidance algorithm guidance robot all not covers up the region movement in any room to carry on the clearing in all directions, because robot guidance along room periphery, therefore it must found her spatial reference diagram, doesnt the robot need any programming where to teach it to go to. This robot simplicity of operator only has 3 buttons:Starts the conclusion as well as the suspension so long as the people in laid aside simply in needed to sweep clear in the region or the room(this kind of completely automatic vacuum cleaner robot was very light, a hand might easy take up it), pressed down starts the button then.2.3 Swiss trilobita vacuum cleaner is small “the trilobita”Is Switzerland develops the production the completely automatic vacuum cleaner. Is small “the trilobita” high 13cm, diameter 35cm, the surface is smooth, assumes the circular, the built-in acquisition radar, may survey rapidly and avoids the table leg, the glassware, the pet or any other obstacles. Once micro processes the small computer to distinguish these obstacles, it may choose the route, and makes to the entire room judges and calculates, guaranteed that the room each corner is swept clear. And so on some do not have the natural barrier place in the staircase stair, so long as has magnet, will be small “the trilobita” then not to surmount. After being small “the trilobita” starts the start, I vivo acquisition radar can survey is away from the recent wall, is being suitable the first wall attracts floor dust and the foreign matter all around, it then can survey like the entire room the pattern, calculates time which the cleaning entire room needs. So long as a close obstacles, it will then establish the line of march, will not leave out each corner. Is small “the trilobita” attracts brushes installs the Chinese dress to have a patent design pulley, may cross the electric wire or the rug edge, is not impeded. When power source insufficiency, will be small “the trilobita” to return to charge automatically Booth to charge voluntarily. If this time room did not have the cleaning to finish, is small “the trilobita” to have the memory function, after sufficient good electricity, return to the original position to continue to vacuum.2.4 American Rumba (Roomba) vacuum cleaner37By the American some institute artificial intelligence laboratory developments wisdom automatic vacuum cleaner, the utilization artificial intelligence revolution and the guidance detection technology, cleans each inch floor intelligently, the real suction hole which and revolving matching is in sole possession of brushes, the clean effect is specially good. By the American TIME evolution was in 2002 one of coolest inventions. So long as presses down the switch, the Roomba completely automatic will assign the region to vacuum cleans, bumps into obstacle servo-assisted steering, will meet the staircase also automatically to detect cannot fall down, the special real suction hole, revolving will brush with revolving side brush the design, regardless of will be the rug or the floor, clean will be very convenient. Highly only some 10 cm, diameter 34 cm Roomba may with case sneak under the bed bottom or the sofa carries on cleans. The Roomba pattern is by mathematics operation idea design movement route. After Roomba start, will follow the spiral-shaped route revolution, by the helix revolution way which will expand gradually covers the space, when will bump will touch the wall or the furniture and so on large-scale obstacle, its special obstacle induction regulator can resist the wall surface protection fuselage not to receive damages, Roomba along the wall or the furniture advance, by now the body side hair brush sweeps into the corner perhaps the furniture edge sully dust detritus in the vacuum cleaner. Have swept clear part of space after the wall or the furniture, Roomba will transfer a 90direction and sweeps the room according or the above route another head, was so alternately redundant, the screw revolution route to be possible back and forth to attract the room, the cleaning finishes namely the automatic stopping. This only heavy 2.5Kg, selects the charge method the vacuum cleaner convenience to be practical, the selling price is only 200 US dollars, already went on the market in Europe and America.2.5 Domestic present situationDomestic also started the related research development work at present, specially was moving robots movement plan and the control aspect has achieved certain achievement, vacuumed the robot for the research developed the omni-directional motion ground cleaning robot, this robots control system could explain the remote control signal accurately, and to organism issuing working order, momentarily received “the eye”(i.e. infrared light electric switch and supersonic sensor) the sensation four direction exterior barrier information, and requested the robot to make straight line or to change the movement according to the above, marched forward, it did not stop rotates the floor to brush, filled in “the stomach” completed the ground in dust, this kind of robot one time charged works sustainably for a half hour, had the intelligent power source management function, lengthened the running time, the average each minute running speed is 15m. in addition, should vacuum the robot to use the open style robot control structure, realizes the hardware to be 38possible to expand, the software to be possible to transplant, may to integrate, enables the robot to have the better function compatibility as the service carrier.
