Accelerometer is an electromechanical device that measures acceleration forces. These forces may be static, like the constant force of gravity pulling at our feet, or they could be dynamic – caused by moving or vibrating the accelerometer. MEMS accelerometers are one of the simplest but also most applicable micro-electromechanical systems. They became indispensable in automobile industry, computer and audio-video technology.

This project makes use of a Relay switch for switching the devices. The Microcontroller decides which device to be operated from the input it gets through the body gestures (MEMS Accelerometer sensor). The Microcontroller is loaded with an intelligent program written using embedded ‘C’ language.

RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency i.e., the higher the frequency, the shorter the wavelength.

In this project we use micro controller, which is programmed to control the input and output modules interfaced to it. The controller makes use of a PIR based input sensor to sense the human being and give us an alert indication.

The controlling device of the whole system is a Microcontroller to which RF receiver, PIR sensor and DC motors are interfaced. The remote control has control buttons interfaced to RF transmitter. Whenever a button is pressed, the data related to that button will be transmitted through RF transmitter. This data will be received by RF receiver and is fed to the Microcontroller. The Microcontroller processes this data and acts accordingly on Robot motors. PIR sensor is interfaced to the Microcontroller which continuously monitors human presence and intimates to the controller. The controller alerts through Buzzer if human presence is present. The Microcontroller is programmed using Embedded C language.

1. Design of real time robot.
