The Robby Garden XP is a robot lawn mower that has a number of advanced features. Those features include the ability to sense where the edge of your lawn is without having to configure or install a virtual perimeter fence.
The sensing isn't perfect mind you as reports say that an actual distinction between grass and soil or stone is needed for example.
The robot lawn mower also has the ability to shred the trimmed grass when it automatically moves around your garden and out of that grass, creates fertilizer to help improve your lawn.
To conserve power the robot lawn mower has sensors built in that measure the height of the grass and adjust the speed of the blades when possible.
It's quite a handy gadget that can be used to cut grass easily every day if needed, however, with a $2,000 price tag I can't see this making it's way in to many gardens. Bring it down to a few hundred dollars and I can see it selling a lot more.
