UAV(unmanned aerial vehicle)
UAV
the introduce of UAV
the use of UAV
the development of UAV
the study of UAV
What Is a UAV
An unmanned aerial vehicle (UAV)， commonly known as an aircraft without a human pilot aboard.
What Is a UAV
Its flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle.
What Is a UAV
The typical launch and recovery method of an unmanned aircraft is by the function of an automatic system or an operator on the ground.Historically， UAVs were simple remotely piloted aircraft， but autonomous control is increasingly being employed.
What Are UAVs Used For?
UAVs are commonly used in both the military and police forces in situations where the risk of sending a human piloted aircraft is unacceptable， or the situation makes using a manned aircraft impractical.
What Are UAVs Used For?
They are also used in a small but growing number of civil applications， such as policing and firefighting， and nonmilitary security work， such as surveillance of pipelines. UAVs are often preferred for missions that are too " dirty or dangerous"for manned aircraft.
types
Global Hawk - UAV
X-47A & X-47B UCAS – UAV
X-43B – UCAV
Prowler II - UAS
UAV development
Sensor fusion: Combining information from different sensors for use on board the vehicle
communication
Communications: Handling communication between multiple agents in the presence of incomplete and imperfect information
avoid the obstacles
Path planning: Determining an optimal path for vehicle to go while meeting certain objectives and constraints， such as obstacles
UAV development
Task Allocation : Determining the optimal distribution of tasks amongst a group of agents， with time and equipment constraints
developed
Most early UAVs are not autonomous at all. In fact， the field of air vehicle autonomy is a recently emerging field， whose economics is largely driven by the military to develop battle ready technology for the warfighter.
study
An unmanned aircraft system (UAS) includes ground stations and other elements besides the actual aircraft. the things that we study is how to communicate among the elements.
