Auto Path Finder Robot
[attachment=25702]
One truck normally takes 150 trips in a day and they want to increase this frequency. There was lot of trouble with designing real time due to so many factors, but I kept in mind when my student friend asked me to design for them, I worked on the project and this is the presentation.
Circuit :
We have fixed INFRA RED sensors on fore side on the robot. The principle of sensors is that black color will normally observe the light where other colors will normally reflects the lights light source is fixed down ward D1 and D3 are infra red lads and D2 and D4 are photo diodes reflected light will fall on the photodiode. IR led. D1 has series resistor R8 limiting the current to 40mA.
