its a ppt on my project at panjab university made by sachin narang and shikhar misra .

1. ARTIFICIALLY INTELLIGENT OBSTACLE AVOIDING ROBOTUSING 8051 SACHIN NARANG UE-6858 SHIKHAR MISRA UE-6878

2. Obstacle avoidance robot is capable of detecting an obstacle in its path. It can avoid the obstacle on its own by changing its direction. Principle: Proximity of obstacle is detected using IR sensors and path is adjusted suitably. Its major application is in Automation of vehicles. INTRODUCTION

3. Philips 89V51RD2 Microcontroller with 64kB flash memory working at 11.0592MHz. Regulated power supply: 7-15V Power indicator LED. Dual full H bridge Motor Driver . DC Motors. ON/OFF switch for power and motor drivers. Infrared sensors. MAJOR COMPONENTS(HARDWARE)

4. TRIC : windows based IDE combining editor, project manager and compiler. iBoard compatible. includes SDCC compiler (an open source software). SOFTWARES USED

5. FLASH MAGIC : windows software from embedded systems academy. Its features includes :Erasing , Programming and Modifying Flash memory. SOFTWARES USED

6. P89V51RD2(Philips) Features 64 KB flash memory 1 KB RAM 32 I/O lines Three 16-bit Timer/Counter 8051 Features

7. Features: Modulated IR transmitter Ambient light protected IR receiver 3 pin interface connectors Indicator LED IR SENSORS

8. MOTOR DRIVER IC L293D 1.Microcontroller provides us only digital logic (1 or a 0). 2. We cant provide polarity from microcontroller. 3. We cant connect motors to Controller as mostly motors runs on voltage higher that +5V, and motors demands high current (depends). Now the solution to above limitations is use of a “H Bridge”.
