Now here’s an idea that I’ve been waiting for—a robotic lawn mower. This is no mere prototype; the Lawnbott can cover lawns up to two acres in size, go up 30-degree slopes and is fully weatherproof. The Lawnbott mows in small increments on a regular basis, navigating its way around the yard using a wire the homeowner installs around the perimeter. It can be ordered from the Lawnbott web site.
