Abstract: Disclosed is a vacuum cleaner. The present disclosure includes a suction motor providing a suction force, a nozzle unit sucking dust on a floor surface, a nozzle motor transferring a drive force to a rotating part, a nozzle shutter adjusting a size of a dust inlet, a battery providing power, a model selecting unit generating information on an operating state corresponding to a drive mode of the suction motor and an open/closed state of the nozzle shutter, an artificial intelligence unit generating probability information through an artificial intelligence model using current information, voltage information and the information on the operating state, and a controller controlling the drive mode in response to the probability information.

Abstract: The present invention relates to a tactile transmission system using a glove type actuator device and a method thereof, and more particularly to a tactile transmission system using a glove type actuator device and a method thereof with which a user can cover his hand and which can directly transmit a movement according to a voltage level to a body part of the user through a piezo disk actuator attached to a position in which a stimulus is transmitted. The tactile transmission system according to one embodiment of the present invention comprises: a touch screen for driving a predetermined program; and a glove type actuator device for vibrating a part which comes in contact with the touch screen to provide curve information about a surface of an object on the program to be displayed on the touch screen.
