Abstract: Various embodiments of the present invention relate to an unmanned aerial vehicle (UAV) and method for operating the same, and an automated guided vehicle (AGV) for controlling movements of the unmanned aerial vehicle.

Abstract: An unmanned aerial vehicle may include: a sensor part configured to acquire inertia information or position information of the unmanned aerial vehicle; and a controller. The controller is configured to estimate the position of the unmanned aerial vehicle by applying the information acquired by the sensor part to an extended Kalman filter and control movement of the unmanned aerial vehicle, based on the estimated position of the unmanned aerial vehicle. The sensor part includes: an inertia sensor configured to acquire the inertia information of the unmanned aerial vehicle; a tag recognition sensor configured to recognize a tag attached to a rack and acquire absolute position information of the unmanned aerial vehicle; and an image sensor attached to the unmanned aerial vehicle so as to acquire an image of the movement environment of the unmanned aerial vehicle.

Abstract: An embodiment disclosed herein relates to an unmanned aerial vehicle for inventory management and a method of operating the same. The unmanned aerial vehicle may include: at least one sensor configured to acquire at least one of inertia information or position information of the unmanned aerial vehicle; a communication unit configured to communicate with a control system; and a processor operably connected to the at least one sensor and the communication unit. The processor may be configured to: receive an inventory survey request from the control system; generate a route information of the unmanned aerial vehicle based on the received request and previously stored spatial information; and perform an inventory survey based on the generated route information.

Abstract: A frame configured of a plurality of links pivotally connected to one another is flexibly bent, and pins that connect the plurality of links that constitute the frame are inserted into and slide in a curve-shaped slot and a slot in a vertical direction so that, even though the frame is bent, the entire length of the frame is increased and ends of the frame can be moved along a straight line that is horizontal with respect to the ground.

Abstract: A wearable robot includes a mechanism unit for assisting an wearer of the wearable robot in walking motion; a detection unit equipped on the wearer's body for detecting a moving direction of an arm of the wearer; and a controller for determining a walking intent of the wearer based on the moving direction of the arm of the wearer detected by the detection unit, and controlling the mechanism unit to produce auxiliary torque corresponding to the determined walking intent.
