font size    

Shanghai-based Donghua University has developed a robot specially for cleaning central air conditioners. It is the first air duct-cleaning robot for which China has its own intellectual property rights and has applied for four patents. Currently dozens of cleaning companies have contacted with the university for commercialization, according to report by Shanghai's Oriental Morning Post.

32 centimeters long, 16 centimeters wide and 21 centimeters high, the robot looks like an electronic toy but outdoes any other products of its kind in China even the world in terms of technology and performance.

According to Mao Limin, member of the research group for the robot, robots developed by foreign countries have difficulties in climbing steps and slopes as they move forward with wheels or double caterpillar, while the newly-developed robot can mount steps of 93 millimeters high and slope of 34 degrees.

Compared with the world advanced level of 200-millimeter rectangle duct, the robot can be used in rectangle duct of 150 millimeters high or below and tube with a diameter of 250 millimeter or above. It is suitable for inspection in small-caliber tube and cleaning and sanitizing in air conditioner duct. The robot can deal with any sophisticated duct.

Mao said, with some renovation and special design, the robot can be used for lunar probe mission.
