LITERATURE SURVEY

Few years ago in robotic system we use to do dataacquisition using manual wheel robot or autonomouswheel robots in commercial & military application or some remote disaster area.

So it was difficult for wheel robots to rome & take survey

for required given location. Also it was difficult for wheel robots to go in building to

climb steps & also in destructed zone.

Aerial robots have much advantages compared to other wheel robots or other robots.

It can find path easily & can travel as fast possible as itcan also move along Z plane compared to other robotwhich travels only in X & Y plane only.

So, we have chosen to build Aerial Vehicle(i.e. Quadcopter) to gather environmental information from remoteareas.



INTRODUCTION

What is the project?

Quad copter platform

Controlled by radio or autonomously

Can carry payload Makes good robotic platform

Upgradeable in the future



INTRODUCTION(CONTINUED.)

In recent times there have been numerous naturaldisasters that have left cities in ruins.

The restoration process can be a very dangerous job due to toxic waste and objects inaccessible to

humans which may require machines to do thework.

Our group offers an advanced solution to thisproblem through the design of a quad copters.

Using this approach, quad copters can reachplaces that are inaccessible to humans because of health risks & can continuously send theinformation about the environmental situation atthose places.



ABOUT THE QUAD COPTER

The Quad copter is a flying object, which flies with

the help of 4 propellers at the end of arm.

Two opposite propellers rotates in one direction for

take-off.

First pair of opposite propellers rotates in clockwise

direction for keeping balance in X-axis.

Second pair of opposite propellers rotates in anti-

clockwise direction for balancing in Y-axis.

The reason of opposite direction of rotation of

opposite pair is the elimination of rotation of quad

copter in Z-axis



PRINCIPLE OF OPERATION OF

QUAD COPTER

Opposite propellers rotates in same directionOne pair of propeller rotates in clockwise direction and

other

pair of Propeller rotates in anti-clockwise direction for

take-off operation of the Quad copter



PRINCIPLE OF OPERATION (CONTD.)

High torque & high rpm is required to lift the quad copter. So,Brushless DC motor is used as it satisfies both the

requirements. To move Quad copter in forward direction, the speed of rotation

of left & right motor is kept constant.

The speed of front motor is reduced & that of rear motor isincreased to some extend.

Similarly, for movement in left & right direction, the respective

motor speed is reduced & the speed of motor that is oppositeto it is increased
