The document summarizes a seminar presentation on agile aerial robots or quadcopters. It describes the key components of quadcopters including frames, motors, propellers, flight control boards and sensors. It also outlines their applications in areas like search and rescue, construction, transportation, and military. Some advantages are their small size, agility and ability to fly indoors without GPS, while disadvantages include potential hacking and need for frequent charging. In conclusion, quadcopters can play an important role in various industries but also have drawbacks that need addressing.

2. CONTENT OUTLINE
 Introduction
 Components
 Flight controls
 Application
 Advantages
 Disadvantages
 Conclusion

3. INTRODUCTION
These are helicopters with 4 motors they are unmanned aerial vehicles,
lightweight ,small in size , protective shielding consist of various
sensors ,laser scanner and can fly indoor without GPS.

4. COMPONENTS OF QUADCOPTER
Frame
Motors
Propellers
Flight control board
Power distribution board
Laser scanner
Transmitter and receiver
Electronic speed controller

5. FRAME
Arms
Centre plate
 Light weight.
 Small size.
 Easy to machine in any shape and size.
Aluminum frame
 Basically Made of aluminum.

6. propellers
4 propellers
• 2 pushers(CW)
• 2 pullers(ACW)
 For balancing the lift and thrust.

7. MOTORS
 High efficiency.
 Produce high torque.
 Get cooled easily when overheated.
 Less noisy.
 Can be operated for longer time.
 Low mechanical wears.

8. Are
connected to
motors

9. gyroscope for Tilt in
forward or backward
direction of motion.
Gyroscope for forward and
to tilt in perpendicular
direction of motion.
Sensor for rolling about its vertical axis.
 Gyroscope is in form of microchip to measure the rotational acceleration.
 Accelerometer is in form of microchip to measure the lateral acceleration.
SENSORS:
FLIGHT CONTROL BOARD

10. LASER SCANNER
Kinect is a motion sensor used for
estimating the position .
• Its range is 1.2to3.5m.
• Area occupied is roughly 6 m^2.
LASER SCANNER
3d laser scanner works by sending a laser beam all
over the field of view then the beams are reflected
back from the objects back to the scanner.

12. ELECTRONIC SPEED CONTROLLER
 For controlling the speed ,
direction and can act as a dynamic
brake of the motors.
 Provide 3 phase ac power supply.

13. BATTERY
 Light weight.
 Can store more power in small punch.
 Long running batteries.
 Can be made of any size and shape.

14. The wings are design in such a manner that
the air above the wings travels faster than
the flow below the wing.as Bernoulli
principle states , the pressure below the
wing will be higher than the air pressure
above the wing. Because of this difference
in pressure ,lift is created. this lift pushes
the wings upward.

16. APPLICATIONS
 Search and rescue:
• Can be send to buildings after natural disaster for rescue
Or can be send to reactor buildings to map radiation level.
 For construction:
• For inspection of a building & monitoring construction
projects.
 Transportation:
• Are in use of delivering goods and products.
 Military uses:
• Using for getting information of the enemies and their location.
 First response:
• can be send as a first responders in buildings to check
biochemical or to get the information how the building
looks like.
 Aerial photography:
• For capturing photos and recording videos of an event.

17. ADVANTAGES
are unmanned.
Small in size .
Agile and light in weight.
GPS not required.
Capable of flying indoors .
 Are cheaper than the Aerial vehicles.

18. DISADVANTAGES
Can be hacked.
Frequent charging may required.
Capable of carrying low weight only.

19. CONCLUSION
 They are play a very important role in agriculture ,military ,commercial purposes etc.
 They could become a part of daily lives such as for private security ,photography ,delivery of
goods, etc.
 These vehicles can be have flight easily as compare to other aerial vehicles.
 They are in military uses to have a quick survey of terrain and the places where soldiers
cannot reach easily.
 There are certain drawbacks of this technology but they can be rectified.
 This technology can be have a very important existence in the coming future but it depends
how we use it protectively or destructively.
