I have a simliar story...

Robile Mowbot is on hold until one of my other robots, Blue Cube running.
There are a few dissimilarities between the two robot's vision and sensor
systems, but many components can be re-used in the mowbot.

Info on the Robile Mowbot has recently been moved to so please update your links.
