ACCELEROMETER  BASED  WIRELESS  GESTURE CONTROLLED  ROBOT  USING 8051 (ATMEL’S  AT89S52)                        The gesture controlled robot is a special kind of robot which works with your hand gestures. It is possible to control the movement of robot in desired direction just with your hand gestures. You just need to wear a small transmitting device in your hand which included an acceleration meter. This will transmit an appropriate command to the robot so that it can do whatever we want. This robot is mainly divide into 2 parts: 1. Transmitter – The gesture device. 2. Receiver – The Robot. Now let’s discus about transmitter first. The transmitter consist of following analog and digital components: 1. Analog accelerometer ( motion sensor ) 2. Comparator (LM324 OP-AMP) 3. 4-bit Encoder (HT12E) 4. RF transmitter (remote control ) THE GESTURE (TRANSMITTER) DEVICE: Gesture Device THE TRANSMITTER SCHEMATIC: the transmitter schematic THE TRANSMITTER

Hi friends...!! Today i am going to show you how to make a simple line tracer robot without using any kind of microcontroller.. The line tracer robot is the autonomous robot which follows the the given black path on white surface.. this robot has ability to sense the given guideline and to drive the motors according to the track as shown in the image. Line tracer following the the track STEP 1: You will need following components to make this robot. LM358 operational amplifier IC 220 ohm resistor 1K resistor infra-red LED photo-diode red LED Geared motors BC547 transistor  (2N3904 or 2N2222 works better.) 5K potentiometer 100 K potentiometer 9V battery and clip. STEP 2: Circuit Diagram: Circuit diagram i made the above circuit to make this simple line tracer.. STEP 3: Please watch the video for more better understanding of functions and working of robot....
