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.

For multiple type sensor robots which is better

For robots that have multiple types of sensors, like adding touch sensors, light sensors, temperature sensors, and a mix, which is easier, Picaxe or Ardunio? Or is there a better microcontroller or setup? I know Lego's NXT has these abilties, but I wanted to know what other setups are out there that work really well or are the easiest to work with or put together.

IR DETECTOR

Ok

So i have a IR detector and it is hooked up to an arduino i have programed it with the help of this blog http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html i am doing the example that is named " How to recieve" 

Problem: whenever i click a button on my remote the number 0 apeers on the serial monitor. What does that mean?

Automated Light Switch - Laziness Prevails!

The Video explains all.

This is my automated light switch, built in a little under 2 hours. Just one application that a servo can be used for.

The servo is just mounted on some hastily cut masonite, the triangular brackets are just glued to the main board with PVA, and everything else is held together with double sided foam tape.

LED fun!

i think this little project would be good for your programming and electronics.

it looks like a lot of fun.

This is actually not a robot, sorry. But.. If you have an old laser-pointer, and are building robots:   Hook up the laser to the microcontroller. Now you can tuen … Read more
