Topic-01
An Unmanned Aerial Vehicle (UAV) is a power-driven crew-less air vehicle. It follows the basic principle of aerodynamics
and uses electric battery or gas-powered engine to fly Chen et al. (2009). In comparison to manned aircraft, UAVs are
cheaper to design and manufacture. UAVs have higher mobility, safety, and flexibility than other manned aircraft. Some
UAVs do not need any specified airfield to take-off and land whereas for manned aircraft an airfield is mandatory.

Key Characteristics of UAVs:

Crewless: UAVs are designed to operate without a human pilot on board.

Remote Control or Autonomous Flight: They can be controlled by a pilot on the ground using a ground
control station or fly autonomously through onboard computer systems.
Aerodynamic Principles: UAVs utilize aerodynamic principles to achieve lift and maneuverability in the
air.
Power Sources: They are powered by electric batteries or gas-powered engines.
Payload Capabilities: UAVs can carry various sensors, cameras, and other payloads to gather data or
perform specific tasks.
Diverse Applications: UAVs are used in a wide range of fields, including agriculture, infrastructure
inspection, surveillance, search and rescue, and delivery services.

Advantages of UAVs:
Cost-Effective:

TOPIC-02
(DRONE TYPES):
What is a drone?
A "drone" is an unmanned aerial vehicle. That is a machine that can fly without a human pilot. Its flight
path is programmed by software or controlled by remote control.

This is just a general definition, there are different terms to refer to this type of aircraft.

RPA or RPAS refers to Remotely Piloted Aircraft and Remotely Piloted Aircraft Systems. This concept
refers to the remote control of an aircraft.
Drone, the most popular name, refers to unmanned aircraft.
Multi-rotor drones

Multi-rotor drones, also known as rotary-wing, are the most widely used type of drones for recreational and
professional use. Their small size and excellent control make multi-rotor drones the best choice for aerial
photography.
 However, the biggest drawback of multi-rotor drones is usually related to the flight autonomy
they offer.
Adding more rotors makes the drone more difficult to control. All those moving parts also
consume extra energy, draining the battery faster.
Most multi-rotor drones have a flight time of less than an hour.
If we want to perform certain tasks that take a long time, we have to have several batteries to
replace them. This also means extra costs.
Fixed-wing drones

Fixed-wing drones are those capable of harnessing air and generating forces that allow them to
stay in the air by taking advantage of their aerodynamics. They are similar in design or aesthetics to
radio-controlled aircraft and are often used to map large areas due to their powerful autonomy. They
take advantage of their aerodynamics and design to keep them afloat, which means they have a longer
endurance and flight speed.

The downside of fixed-wing drones is that they tend to be more expensive compared to multi-rotor drones. They
require a large, clear space to take off and land, just like airplanes. Some larger models also require specialized
ground equipment to help them take off and land. In addition, fixed-wing drones can only fly forward, so they do
not offer the same maneuverability as multi-rotor drones.
Single-rotor helicopter drones

Powerful and durable, single-rotor drones look similar in construction and design to actual helicopters, with only
one rotor to provide power, plus a tail to control direction and stability. Combining the advantages of tiny multi-
rotor drones and single-rotor drones, they are better suited to carry larger payloads and fly more efficiently than
multi-rotors. Single-rotor devices typically use gas engines rather than batteries, which greatly increases their flight
time.

However, these drones tend to be larger and more complex than other types of UAVs. This means they
are more expensive and more difficult to operate, and their larger blades can make them more
dangerous.
Fixed-wing hybrid VTOL drones

As the latest drone technology to be introduced, fixed-wing hybrid VTOL drones refer to fixed-wing
aircraft that have been modified to take off and land vertically. They combine the long-range and flight
time of fixed-wing UAVs with the vertical takeoff capability of rotary-wing devices, eliminating the
drawbacks of fixed-wing UAVs that require large spaces for takeoff and landing. They are designed for
mapping, power line inspection, surveillance, agriculture, and rescue operations.

However, this VTOL drone tends to be unsuitable for beginners, and the more advanced
technology puts it at the high end of the fixed-wing drone market in terms of cost.

TOPIC-05
UAV Ultra sonic sensors:
Ultrasonic sensors are not commonly used in unmanned aerial vehicles (UAVs) due to various
factors such as size, weight, and limitations in range and accuracy.

 Ultrasonic sensors use sound waves with frequencies higher than the upper limit of human
hearing (typically above 20 kHz) to detect objects and measure distances.
 They work by emitting ultrasonic pulses and measuring the time it takes for the sound waves to
bounce back after hitting an object.

In the context of UAVs, ultrasonic sensors could be used for:

(1) Obstacle Avoidance:

Ultrasonic sensors can be employed to detect and avoid obstacles during flight. By measuring the
distance to objects in the UAV's vicinity, they can provide data to the flight controller to adjust the UAV's
path and avoid collisions.

However, due to their limited range and sensitivity, ultrasonic sensors are not suitable for high-speed
UAVs or long-range obstacle detection.

(2) Landing Assistance:

Ultrasonic sensors could assist in precision landing operations.

By measuring the distance between the UAV and the ground, they can provide feedback to the
UAV's autopilot system for smoother and more accurate landings, especially in situations where GPS
signals may be unreliable or unavailable.
Ultrasonic sensors have some limitations in UAV applications:
Limited Range:
Ultrasonic sensors typically have a limited detection range, typically up to a few meters. This
range may not be sufficient for UAV operations that require longer-distance object detection or terrain
mapping.
Environmental Interference:
Ultrasonic sensors are susceptible to environmental factors such as wind, temperature,
humidity, and acoustic reflections, which can affect their accuracy and reliability. They may not perform
well in outdoor environments with varying conditions.
