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.

COMPONENTS OF QUADCOPTER

Frame Motors PropellersFlight control boardPower distribution boardLaser scannerTransmitter and receiverElectronic speed controller

FRAME

Arms Centre plateLight weight. Small size.Easy to machine in any shape and size.

Aluminum frameBasically Made of aluminum.

propellers

4 propellers2 pushers(CW)2 pullers(ACW)For balancing the lift and thrust.

MOTORS

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

Are connected to motors

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

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.

ELECTRONIC SPEED CONTROLLER

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

BATTERY

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

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.

Bernoulli principle

PRINCIPLE OF UPLIFTMENT

Bernoulli principle

ROLL ,PITCH AND YAW

12341423All 4 motors are having same RPM.2 and 3 have higher RPM than 1 and 4. decrease in RPM.

Increase in RPM.Increase in RPM.Decrease in RPM.

APPLICATIONS

Search and rescue:Can be send to buildings after natural disaster for rescueOr 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.

ADVANTAGESare unmanned.

Small in size .

Agile and light in weight.

GPS not required.

Capable of flying indoors .

Are cheaper than the Aerial vehicles.

DISADVANTAGESCan be hacked.

Frequent charging may required.

Capable of carrying low weight only.

CONCLUSIONThey 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.
