An unmanned aerial vehicle according to the present invention may comprise: a rotor-blade for providing thrust according to generation of main stream; and a safety guard disposed to surround the rotor-blade. The safety guard may comprise: a guide member which is disposed coaxially with the rotor-blade while having a gap between the guard member and the end of the rotor-blade, so as to stabilize, when the rotor-blade rotates, a flow field suctioned by a negative pressure, and stably boost a discharge flow when the pressure is changed to a positive pressure; and a diffuser which is disposed coaxially with and radially spaced apart from the guide member, and generates a secondary flow toward the main stream to increase a flow rate.

Unmanned aerial vehicle comprising safety guard

Disclosed is a robot including a variable length unit coupled to one section of at least one arm unit, wherein the variable length unit may include a motor, a first cam having at least one slit having a specific inclination in one area thereof, and a second cam, at least a portion of which is disposed in an interior of the first cam, and having at least one first boss that passes through the at least one slit of the first cam, wherein the first cam may be rotated through driving of the motor, the second cam may be linearly moved while the at least one first boss is guided by the at least one slit in correspondence to rotation of the first cam, and a length of the at least one arm unit may vary in correspondence to linear motion of the second cam.

Robot comprising arm unit of length variable structure

A cable guide device of an articulated robot is disclosed. The disclosed cable guide device can comprise: a base; at least one rotary arm rotatably coupled to the base in an articulated form; at least one cable passing through the base so as to be connected to the rotary arms; a cable guide block coupled to a driving unit within the base; a sliding groove formed on the outer peripheral surface of the cable guide block; and a cable friction reducing device member which is coupled to a portion of the cable accommodated in the base and which rotates along the sliding groove together with the portion of the cable according to the rotation of the rotary arms.
