  1. 1. LEVEL 3 (AUTONOMOUS) 18 th – 19 th FEB 2006 BY Abhinay Badhan Santosh Sonawane (TE Instru.) (TE Comps.) [email_address] [email_address] 9869773648 9324259014
  2. 2. Gist of Autonomous Competition
  3. 3. <ul><li>Sense the path and Depending on situation ROTATE CAR </li></ul><ul><li>pass info. to the uC give corresponding signal LEFT / RIGHT </li></ul><ul><li>in terms of LO and HI to motor driver circuit BY 90/180 deg. </li></ul><ul><li>electrical signals…… </li></ul>Basic Block Diagram
  4. 4. Power Supply Unit
  5. 5. Different Types of Sensors… Radar Microwave Radar Ground Radar Sick Laser LIDAR (Light Detection and Ranging) Scanning Laser detector Electrostatic Ultrasonic Polaroid Sonar Mini Polaroid Sonar
  6. 6. Different Types of Sensors….contd Piezo Electric Ultrasonics Piezo Sonar Board Infrared Ranging Microphone Sound Buzzer Linear Arrays Position Sensitive Device Camera
  7. 7. Which sensors to use?
  8. 8. Basics of Path (Line) sensing IR Photo Transmitter Transistor
  9. 9. Configuration of Sensors
  10. 10. Passing the Info. to uC Circuit (Basic Circuit) <ul><li>Initially o/p of C is low (0.71 to 1.78 V) </li></ul><ul><li>After sensing o/p changes to high (2.3 to 5 V) </li></ul><ul><li>To vary the sensitivity vary the Potentiometer </li></ul><ul><li>In Short , </li></ul><ul><li>LED glows when no signal is sensed by PT </li></ul><ul><li>LED is OFF when PT senses and o/p is high. </li></ul>
  11. 11. Interface with motors
  12. 12. Hardware And Assembly <ul><li>Should be as rugged as possible </li></ul><ul><li>Simple </li></ul><ul><li>Not Complex </li></ul><ul><li>Better if you use ‘PLUG N PLAY’ </li></ul><ul><li>Versatile </li></ul>
  13. 13. Circuit Design and Construction <ul><li>TRY TO AVOID WIRES </li></ul><ul><li>Use different types of detachable connectors </li></ul><ul><li>Make all circuitry more towards compact </li></ul><ul><li>If possible make a layout of a single PCB </li></ul><ul><li>Versatile </li></ul>
