Abstract:
A telepresence robot may include a manual navigation unit configured to move the telepresence robot according to navigation information received from a user device; an autonomous navigation unit configured to detect environment of the telepresence robot and control the movement of the telepresence robot using the detected result; a motion control unit comprising a database related to at least one motion, the motion control unit configured to receive selection information on the motion of the database and actuate the telepresence robot according to the selection information; and an output unit configured to receive expression information of a user from the user device and output the expression information. The telepresence robot may be applied to various fields such as language education by a native speaking teacher, medical diagnoses, teleconferences, or remote factory tours.
Abstract:
The present invention provides a gas sensor, including: a sensor substrate provided with an electrode; and a thin layer of sensor material formed by spraying a solution in which metal oxide nanoparticles are dispersed onto the sensor substrate. The gas sensor is advantageous in that a sensor material is formed into a porous thin layer containing metal oxide nanoparticles having a large specific surface area, thus realizing high sensitivity on the ppb scale and a high reaction rate. Further, the gas sensor is advantageous in that it can be manufactured at room temperature, and the thickness of a sensor material can be easily adjusted by adjusting the spray time, so that a thin gas sensor or a thick gas sensor can be easily manufactured.
