A robot cleaner includes a case, a suction device provided in the case, a suction nozzle for sucking dust from a floor by driving of the suction device, a dust collection device for collecting foreign substances contained in the air sucked via the suction nozzle, a driving unit for allowing the case to drive automatically, a controller for controlling the driving of the suction device and the driving unit, and for generating cleaning history information comprising map information on a cleaning area and moving path information, a memory unit for storing the cleaning history information; and a wireless communication module provided in the case to transmit the cleaning history information to the external terminal, when the external terminal asks the cleaning history information.

A robot cleaner is disclosed. The robot cleaner includes a main body defining an outer appearance thereof, a suction device mounted inside the main body and including a suction motor and a suction fan, a suction port for sucking foreign substances from a floor upon operation of the suction device, a dust collection device for collecting foreign substances from air sucked through the suction port, one or more wheels for enabling the main body to travel autonomously, and a control unit for controlling the operation of the suction device and the wheels. The suction motor includes a stator and a rotor disposed around the stator and formed to be rotated with a rotating shaft. The rotor includes a first magnet for rotating the rotor around the stator, and a second magnet for preventing the rotating shaft of the suction motor from moving axially within a range of end play.

A retroreflective article enabling to retroreflect incident light in its incident direction, and the retroreflective article including at least one retroreflective element, the retroreflective element including at least one reflecting corner comprised of a pair of corner reflecting surfaces which meet at dihedral angle of about 90 degrees; and a pair of vertical reflecting surfaces which are formed on both ends of the reflecting corner to be substantially perpendicular to a corner of the reflecting corner with a distance which is smaller than the highest vertical height and which meet at dihedral angle of about 90 degrees for the pair of corner reflecting surfaces. This retroreflective article has higher retroreflective ratio and wider available retroreflective range, and it is designed to be freely changed its main reflecting direction having the highest retroreflective ratio.

Retro reflector including at least one corner and two mutually parallel vertical faces

A robot cleaner comprises a main body having a suction port at a bottom surface thereof, a pair of wheel assemblies disposed at both sides of the main body, and configured to move the main body, a dust box mounted to contact the bottom surface of the main body, and configured to collect dust sucked through the suction port, a filter unit configured to filter air discharged from the dust box, a suction fan configured to form a suction pressure on a suction channel defined by the suction port, the dust box and the filter unit, and a battery disposed at a side of the dust box.
