Husqvarna launches state of the art robotic lawn mower.

According to Husqvarna.com…. Our robotic mower is able to maintain small to large lawns in any weather, with rough terrain and slopes up to 35%. When it meets an obstacle it stops and redirects itself. It also knows when it needs to be charged. The robotic mower is also equipped with an attentive anti-theft system and built-in safety measures. The unit uses extremely low energy consumption allowing the robotic mower to operate at a fraction of the cost of traditional lawn mowers. And, because it is electrically powered, the robotic mower produces no harmful emissions.
