Disclosed is an unmanned aircraft including: a housing; a drive unit that is formed in such a manner that the housing is moved; multiple UWB communication modules that are arranged a distance away from one another and that receives a wireless signal from an external device; a sensor unit that detects movement of the housing; and a control unit that calculates a distance between the external device and the housing, using pieces of movement information which are output by the multiple UWB communication modules and the sensor unit, and that controls the drive unit in such a manner that a specific distance between the external device and the housing is maintained.

Unmanned aircraft and method of controlling the same

An electromotive walking assistance device includes a drive unit including a plurality of wheels and a motor for driving at least on portion of the plurality of wheels, a sensor unit sensing a distance from a user, a manipulation unit sensing a user's manipulation, and a controller controlling the motor based on a signal of the distance from the user and a signal of the user's manipulation.

Disclosed are an autonomous mobile cleaner, and a method for moving the same. A user's intention may be estimated based on a size and a direction of a tensile strength applied to the air pipe, and a cleaner body may move according to the user's intention. This can allow the cleaner to autonomously move. Besides, the autonomous mobile cleaner can always and precisely detect a user's operation without having interference with obstacles, using a displacement of the air pipe. Further, the fabrication costs can be reduced and displacements in all directions can be calculated, by using a hall sensor and a magnet member. Further, a user's efforts to operate the cleaner can be minimized, and can be prevented damages of the air pipe, a connection part between the air pipe and the cleaner body, etc. due to an excessive force.
