The document provides an overview of drone technology, defining drones as unmanned aircraft capable of remote control or autonomous flight. It categorizes drones into four main types—multi-rotor, fixed-wing, single-rotor, and fixed-wing hybrid VTOL—along with their advantages and disadvantages, including applications in various fields like surveillance and photography. A timeline highlights the historical development of UAVs from their first use in 1783 to their increasing prevalence in civilian applications by 2020.

3. WHAT IS DRONE?
• A drone is an unmanned aircraft. Drones are more formally
known as unmanned aerial vehicles (UAVs) or unmanned aircraft
systems. Essentially, a drone is a flying robot that can be
remotely controlled or fly autonomously using software-
controlled flight plans in its embedded systems, that work in
conjunction with onboard sensors and a global positioning
system (GPS).

4. TYPES OF DRONES
Here’s a rundown of the four main types of
drones, their uses, their strengths and
weaknesses:
1.Multi-Rotor Drones
2.Fixed-Wing Drones
3.Single-Rotor Drones
4.Fixed-Wing Hybrid VTOL

5. Multi-Rotor Drones
Multi-rotor drones are the easiest and cheapest option for getting an ‘eye in
the sky.’ They also offer greater control over position and framing, and
hence they are perfect for aerial photography and surveillance. They are
called multi-rotor because they have more than one motor, more commonly
tricopters (3 rotors), quadcopters (4 rotors), hexacopters (6 rotors) and
octocopters (8 rotors), among others. By far, quadcopters are the most
popular multi-rotor drones.

6. Fixed-Wing Drones
A fixed-wing drone has one rigid wing that is designed to
look and work like an aeroplane, providing the lift rather
than vertical lift rotors. Hence, this drone type only needs
the energy to move forward and not to hold itself in the air.
This makes them energy-efficient.

7. Single-Rotor Drones
Single-rotor drone types are strong and durable. They look
similar to actual helicopters in structure and design. A single-
rotor has just one rotor, which is like one big spinning wing,
plus a tail rotor to control direction and stability.

8. Fixed-Wing Hybrid VTOL
Hybrid VTOL drone types merge the benefits of fixed-wing and rotor-
based designs. This drone type has rotors attached to the fixed wings,
allowing it to hover and take off and land vertically. This new category of
hybrids are only a few on the market, but as technology advances, this
option can be much more popular in the coming years. One example of
fixed-wing hybrid VTOL is Amazon’s Prime Air delivery drone.

9. Advantages of Drones
UAVs were most often associated with the military. They were initially used for anti-
aircraft target practice, intelligence gathering and, more controversially, as weapons
platforms. Drones are now also used in a range of civilian roles, including the
following:
•search and rescue
•surveillance
•traffic monitoring
•weather monitoring
•firefighting
•personal use
•drone-based photography
•videography
•agriculture
•delivery services

10. Disadvantages of Drones
After several years of practice using drones, a list of typical hazards accompanying their use
can be formed:
•Short flight time
•Statistics of the dangerous or criminal use of drones
•They are easily affected by the weather
•Drone collisions with people. Risk of injury
•Flights over areas where flights are prohibited or inappropriate
•Dangerous proximity to aircraft, including helicopters, etc.
•Collisions with buildings, structures, monuments
•The use of drones for the transport of criminal goods, primarily drugs
•Voyeurism
•Hooliganism, terrorist acts
•The use of commercial drones for military purposes
•The dangers of using data collected by commercial UAVs
