IR navigation beacons

There have been several previous blogs and forums on LMR concerning different methods of robot navigation and room recognition. I have decided to make some IR beacons for experimenting with.

My theory is that if each room has at least 3 beacons spaced around it then the robot can not only triangulate it's position within the room but also determine what angle it is facing. Each beacon sends out a different identification code. This allows the robot to know which room it is in.

"Moooo" Rare Swiss Cow Project has begun

Following on from the Laser Experiments i have decided to attach it to some kind of walking Robot.

I am now a avid fan of Theo Jansen -  after rik brought him to light in his Blog.

So far i have Prototyped two pairs of "Theo" legs using "MindStorms" as an experimental base.

It worked better than i could have imagined - these legs go like a Cow on its way to the milking parlour.........

Only problem now is what  medium shall i use to make the final version.....

Basic Triagulation Positioning System

3 Friends and I are building an autonomous tennis ball collecting robot for a 4th year design project for our undergrad.

We need a way for the robot to keep track of its position on the tennis court (in doors) and we are thinking of using 2 beacons to emit signals with a receiver on the robot. Has anybody done something like this before? Has anyone heard of pre-packaged solutions that do just this? A USB module would be ideal (we are using a netbook to control the robot), but we are not at all opposed to building the positioning system from scratch.
