Line Following Sensors
January 24, 2013
I am making a line following robot for a competition in Australia called "Robocup Junior". It involves following a line, also, taking shortucts indicated by a green square. At the suggestion of one of the friendly LMRians I invested in an IR Sensor board that can follow the line perfectly. The only problem I have been having is that white and green have the same readings (must be a problem with infra-RED and GREEN being different, or something:)
So I am creating this thread to see if anyone has had any experience with any light or colour (color) sensors.
The sensor needs to have a conserable reading difference between black, white, green and silver (aluminium foil). An optimal reading distance of more than 5mm would be ideal.
Thanks for your help.
P.S. - Ease of programming is also quite important as I am a beginner.
