Dyson Eye 360 the robotic vacuum cleaner that sees everything 360


 Dyson British firm , originally of bagless vacuum cleaners , introduced 360
 Eye , equipped with an obstacle detection system 360 . The vision
 would make it more independent and more efficient than its competitors. It required more than
 15 years of development , mobilized 200 engineers and cost 36 million euros.
This autonomous robotic vacuum cleaner literally see the room in which it
 is and its navigation system mapping its environment
 to determine a course. It is equipped with rubber tracks
 supposed to ensure a better handling and allow it to evolve over
 any type of surface. Its rotating brush and suction mouth cover
 the entire width of the machine to suck in the corners and on the
 board walls.
 Dyson Eye 360 has a lithium-ion battery which ensures 20
 minutes remaining before it returns to its charging station.
 Obviously , the vacuum cleaner utilizes cyclonic bagless technology . There
 robotics part rests on two innovations that make the 360 one of the Eye
 autonomous vacuum cleaners the most sophisticated to date. The vision system
 360 consists of a camera filming the environment at a rate
 30 frames per second with an angle of 45 °. It is topped by a
 panoramic lens and installed on the top cover of the robot . 
The shutter speed of the camera is synchronized with the
 displacement speed of the device , allowing it to carried
 kill a calculation of accurate position to the millimeter . images
 collected is processed using the technology cartogra-
 phy and simultaneous localization called SLAM ( Simultaneous
 Localization And Mapping) . Infrared sensors detect
 obstacles.
 Everything is controlled by a software called Dyson Digital Algebra
 that combines algebra, probability theory, trigonometry and
 geometry. Dyson explains that this navigation system takes
 benchmarks in a room to triangulate its position
 to find out where it is , where it happened and where it should go .
 Its development has required 100,000 hours of work. The second innovation is its digital electric motor.
 With an output of 100 watts, it is based on a neodymium magnet whose speed is controlled electronics
 cally and can reach 78,000 revs / minute. Current speed much higher than that of an electric motor
 DC (about 20000 revolutions / minute ) achieves a much higher suction power .
 Dyson says his engine is also smaller and lighter . The robot can be controlled remotely from a
 smartphone or tablet with Android and iOS apps that allow to program and monitor
 cleaning, materialized on a map
