In this project we are using another technology is VOICE RECOGNISATION which can also be easily interfaced. If the people in LIFT want to move to up and down using his/her voice command the lift moves to the required position of that person.Now a days we can find huge no of apartments crowded in nearby area with multi storage building capacity.The main purpose of designing this project is to operate the elevator by using voice commands. The elevator has to be moved vertically by recognizing our voice commands by using speech recognition module. The project is built around AT89S52 micro controller voice recognition module is interfaced with micro controller to drive the elevator.  A 16X2 LCD display is used for the display of elevator where it is currently placed and its status can be obtained 

This project involves a combination of PWM (pulse width modulation) and ADC (Analog-Digital converter) to drive a DC motor at various speeds and in both clock and anti directions.

PWM is a concept with which one can modify the pulse voltage varying it from 0% duty cycle to 100%.

Duty cycle represents the time for which pulse is high when compared to the full pulse length.

A Gesture Controlled robot is a kind of robot which can be controlled by using our hand gestures. Which will be helpful for handicapped person who are depends of other person. In this robot you just wear a transmitting device on your hand. A transmitting device will send commands as per hand gesture movement and receiver will work according to that commands. In this project at receiving side we just put two DC motor for Left, Right, Forward and reverse direction.It is an autonomous robot in which the accelerometer gesture controls the motion of robot. The accelerometer can be attached on hand or on gloves with the help of microcontroller to control the robot.
