I'm working on a little nav idea that my robot can find my 'base' which is sweping a bright red led 'laser' over the area.

(...) I guess no one is using Perl to communicate with the NXT over Bluetooth. Or everyone is busy building bots. I found something that seems to work reliably on my HP Laptop running Windows 2000.
