1) Fault detection of multirotor; whether quadcopter, hexacopter, or octocopter
2) Cracks can be detected automatically, and it can also be performed across various drone modes simultaneously without the need to upload a new algorithm to the system or prototype
3) The future application that the technical output of this project likely to have is the real-time portable vibration-based fault detection device, which not only applicable to drones, but also to rotating
