Unmanned aerial vehicles (UAVs) are aircraft without pilots and can be remotely controlled or fly autonomously. UAVs were first used for military purposes in 1849 and have since been developed for various applications. They are used for tasks like reconnaissance, combat, and civil/commercial purposes. UAVs provide advantages like safety in dangerous tasks but also have disadvantages like susceptibility to interference and potential program failures. Looking ahead, the use of UAVs is expected to expand to more applications and users, though development challenges may arise as the technology matures.

3. UAV -- Definition
The UAV is an acronym for Unmanned Aerial Vehicle,
which is an aircraft with no pilot on board. UAVs can be
remote controlled aircraft or can fly autonomously based on
pre-programmed flight plans or more complex dynamic
automation systems.

4. UAV -- background
The earliest recorded use of an Unmanned Aerial Vehicle
for warfighting occurred on August 22, 1849.Soon after,
on September 12, the Hewitt-Sperry Automatic Airplane,
otherwise known as the “flying bomb” made its first
flight, demonstrating the concept of an unmanned
aircraft. They were intended for use as cruise missile.

7. UAV -- advantages & disadvantages
Advantages:
❤good shapes,，moderate in size , high configurations
superior performance
❤help people with dull, dirty and dangerous works
❤cheaper，more capable fighting machines in military
❤save manpower

8. UAV -- advantages & disadvantages
Disadvantages：
❤not applicable to complex terrain and bad weather
❤easy to be electronic interference
❤programs are easy to fail
❤fear of air defense fire

9. UAV -- future development
A possible future research is aimed at performing forest
surveys to further evaluate the UAV’s potential within the
forestry industry. These surveys will be designed to assess
the UAV as a tool which allows forest managers to make
more informed decisions on pruning and thinning regimes,
monitoring tree health and defoliation.
