Room positioning robot
Thinking about the old 'ray cast' 3d games such as Castle Wolfenstein, I think maybe it might be possible to run a raycast in reverse.
By using a light sensor to take a horizontal 'slice' of the current field of vision, then mapping the results back to a bitmapped map of the room - refining the room bitmap when the posisition is known / refining the position from the bitmap when not sure of the posisition - I think it might be possible to acheive that holy grail of robotics, a simple, cheap, position sensor.
It means of course that only a 'flat' map of the room is possible, but considering the robot will trundle about the floor, this is not too much of limitation.
