The reed switch is a good idea, but how close will they need to be for it to work? maybe i could get a powerful magnet, but will it only work from one side of the beacon? and no i dnt have to option of the bot making contact with the beacon, the object avoiding system will not allow the bot to hit anything (hopefully!) thanks

You are joking surely?? anyway.. what i mean by beacon is a device that will send out infra-red light, with a fixed position... like placeing a torch on the floor, and then my robot going towards the light... My robot wil look for IR light, and go towards it.. but i need it to know when it is there rather that it just keep pushing it around, and dnt know how.. thanks for the help..

For my college project i am building a robot that will drive towards an IR beacon, avoiding objects along the way. i already have ideas of how to do the most of it, but there is just one thing i don't know what to do about. How can i make my robot 'know' when it has found the beacon... i can imagine it getting to it, but then just pushing it around in a much like carrot hanging in front of a donkey situation!! I want it to stop when it gets to the beacon. This has got to be relatively simple and cheap.. Any ideas?? I'm stumped. :( Thanks Leigh
