An aerosol spray apparatus and a method of forming a film using the aerosol spray apparatus are disclosed. The aerosol spray apparatus in accordance with an embodiment of the present invention includes: a carrier gas injection unit, which forms carrier gas by vaporizing liquefied gas and increases the pressure of the carrier gas; an aerosol forming unit, which forms an aerosol by mixing the carrier gas with powder; and a film forming unit, which sprays the aerosol in a normal pressure environment such that the film is formed on the surface of the board. The apparatus can perform a coating process with no restriction of the type and size of powder, simplify the process because the film can be formed in a normal temperature and pressure environment, and control a wide range of film thickness in a short time.

A system for preparing nanoparticles using non-thermal pulsed plasma is provided. The system comprises a reaction chamber having two divided regions, i.e. a first region where nanoparticles are to be formed and a second region where the nanoparticles are to be received, to prevent the formation of a thin film of nanoparticles in the second region. The use of the system enables the preparation of nanoparticles with improved uniformity and high collection efficiency. In addition, collection and deposition of nanoparticles can be simultaneously performed in the second region. Therefore, the system can find applications in various fields, including devices, secondary cells and sensors. Further provided is a method for preparing nanoparticles using the system.

A robot cleaner, a system thereof, and a method for controlling the same. The robot cleaner system includes a robot cleaner that performs a cleaning operation while communicating wirelessly with an external device. The robot cleaner has a plurality of proximity switches arranged in a row on a lower portion of the cleaner body. A guiding plate is disposed in the floor of the work area, the guiding plate having metal lines formed in a predetermined pattern, the metal lines being detectible by the proximity switches. Since the recognition of the location and the determination of traveling trajectory of the cleaner within a work area becomes easier, performance of the robot cleaner is enhanced, while a burden of having to process algorithms is lessened.
