A multirotor UAV (Unmanned Aerial Vehicle) is an unmanned aircraft that relies on the coordinated rotation of three or more rotors to generate lift and thrust, enabling vertical takeoff and landing (VTOL), hovering, and agile flight.

In terms of the overall structure, a drone battery can be disassembled into three major modules: the core energy unit, the safety management system, and the external protection and connection components.

The following systematically sorts out the main types, technical features and typical applications of UAVs from six core dimensions: flight platform structure, core purpose, weight/size, power system, degree of autonomy, and operating environment.

These two concepts are not equivalent; instead, they have an inclusive “part-to-whole” relationship—UAV is the core component of UAS, while UAS is the complete system that supports UAV in fulfilling its functions. Below is a detailed breakdown and comparison of the two from the perspectives of definition, composition, application scenarios, differences in terminology usage, related extended concepts, and industry value.

The following provides a systematic decision-making framework from four dimensions—”clarifying personal positioning → screening course types → controlling core indicators → avoiding risks”—to ensure the selected course is both practical and cost-effective.

The following provides systematic recommendations for the implementation of drone teaching from ten dimensions, including preliminary preparation, curriculum design, teaching implementation, and safety management, taking into account different educational stages and teaching objectives (interest cultivation / vocational training/competition preparation).
