Description

An Apparatus for Inspecting a Multicopter The present invention relates to a multicopter inspection device, and specifically, to a multicopter inspection device that detects the operating state of a multicopter by means of a plurality of sensors and investigates the state of each component forming the multicopter. A multicopter is an aircraft that uses two or more rotors or propellers to take off or land, or to propel or rotate, and can be used for various purposes in diverse industrial or military fields. Among such multicopters, quadcopters with four wings are widely used due to their stable flight conditions. A multicopter includes components such as a frame, propellers, an ESC (Electric Speed Controller), motors, and batteries, and for the multicopter to operate stably, each component must be maintained in an appropriate operating state. Furthermore, to ensure the operational stability of the multicopter, the condition of each component must be checked periodically, and components must be repaired or replaced as necessary. To this end, the condition of each component needs to be detected periodically. Patent Publication No. 10-2012-0006807 discloses a safety diagnostic system for a helicopter rotor. Patent Registration No. 10-2303118 discloses a method for diagnosing thrust abnormalities in a multicopter. In addition, Patent Publication No. 10-2024-0093267 discloses an actuator diagnostic device for an unmanned multicopter, a control system for an unmanned multicopter, and a method for diagnosing actuator failures for an unmanned multicopter.
