ABSTRACT: • An amphibious robot as the name suggests

is a robot that goes on land, on water and in water. Amphibious bot can be operated in various means. It can be operated manually as well as it can be an autonomous robot.

• The main objective of this project is to make an amphibian robot, which can travel on land, on water and inside water. The part where we need to build a robot that can transverse on land is quite easy. But as

• we need it to float on water, we design the bot in such a way that it is slightly positive buoyant. The metal detector works on the principle that when a current passes through the coil, it produces a magnetic field around it.

COMPONENTS USED

• Bluetooth module

• Microcontroller(atmega8}

• Motor driver

• Connecting wires

• Voltage regulator

MECHANICAL PART:

Acrylic

Float

Motors

Motor drivers and hardware

PCB

FEATURES:

• An Amphibian Bot represents an amphibious robot which has the following features:

• A robot which can move on land as well as on (or under) water.

• A robot which uses the principle of buoyancy to keep itself floating.

• It is made up of Acrylic body.

• Its wheels are made up of plastic having acrylic flaps

• It works wirelessly controlled by remote.

• It also consists of metal detector.

WORKING

• Working of this amphibious bot is very simple it consists of 4 dc 500rpm

motors. Its movement is controlled wirelessly through HC-05 Bluetooth module.

The program is given to the microcontroller according to the logic. The

Bluetooth receives command and transmits it to the microcontroller where the

microcontroller in turn gives that command to L293D. With the help of which

the motors start working according to the command.

TWO MAJOR PRINCIPLES

•Buoyancy • Buoyancy = weight of displaced fluid.

• Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object

• Float • The FLOAT is the world’s first and only dynamic multidirectional, overhead weight support

• The FLOAT overtakes up to 60% of your body weight

PROGRAM:

• #include<stdio.h>

• Void main()

• {

• Char x;

• while (1)

• {

• x=getchar();

• if(x=='F')

• {

• #include<stdio.h>

• Void main()

• {

• Char x;

• while (1)

• {

• x=getchar();

• if(x=='F')

APPLICATIONS

• wireless controlled automated vehicle capable of moving on land and on under

water has been proposed.

• metal detector which uses VLF (very low frequency) technique to detect the metal

and is very useful in many applications.

• It can be installed with a variety of sensors and also surveillance camera and can be

used for surveillance purposes

• It can be installed with a variety of sensors and also surveillance camera and can be

used for surveillance purposes

.

• Potential operations for such a robot include: mine clearing, terrain mapping,

and scouting potential approach lanes for amphibious in naval.

• errestrial and aquatic mobility, control, navigation, communication, obstacle

avoidance, and sensor payment remain critical issues to be resolved for

successful operation.

CONCLUSION:

• This will greatly simplify the autonomous control problem and give the vehicle

a versatility that no amphibious robot has yet enjoyed. This design is very

useful for the purpose of defence as it is user-friendly and automated so as

the loss of life in defence can be reduced as it can be operated from safer

distance. This design is very economically best
