Line Following Sensors

Hello everyone,

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.

Computer On Wheels Controller

Hi guys,
 
 
 
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
 
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

Super Brilliant Avoid Obstacle Strategies - Open Question

I have built a Bot with Arduino as MCU and wish to give it a life of its own.

Has anyone Created a "Super Brilliant" Strategy for avoiding obstacles ?.

So far my bot does this (rather On/Off control) :-

(1) When it detects an object Right it turns Left until the coast is clear and carries on with its original direction.

(2) When it detects an object Left it turns Right until coast is clear and carries on with its original direction.

How do you make a line follower?

i just want to know how to make a line follower, like the equipment needed. if there is a walkthrough, please give me the link. if there isn't, can you tell me how or give me a link to a site that does?
