ABSTRACT:

• The Embedded Technology is now in its prime and the wealth of Knowledge available is mind-blowing.

• Embedded System is a combination of hardware and software.

• Embedded technology plays a major role in integrating the various functions associated with it.

• This needs to tie up the various sources of the Department in a closed loop system.

• This proposal greatly reduces the manpower, saves time and operates efficiently without human interference.

• This project puts forth the first step in achieving the desired target.

• With the advent in technology, the existing systems are developed to have in built intelligence.

Existing System:

• Certain methods to control the robot by using a

separate device especially for the robot.

• Wireless controlled vehicles had been

extensively used in a lot of areas like unmanned

rescue missions, military usage for unmanned

combat and many others

3EG Technologies

Drawbacks of existing system:

• Working range, and limited control

• The wireless unmanned robots typically make

use of RF circuits for maneuver and control.

4EG Technologies

Proposed System

• Dual tone multi frequency (DTMF) signaling

is used for telecommunication signaling over

analog telephone lines in the voice frequency

band between telephone handsets and other

communication devices and the switching

center
