A robotic lawn mower is an autonomous robot used to reduce yard lawn. A normal robotic lawn mower needs the customer to set up a boundary wire around the yard that specifies the spot to get mowed. The robot makes use of this cable to locate the limit from the area to be cut and perhaps to discover a recharging dock. Robotic mowers are designed for preserving as much as 20,000 m2 (220,000 sq feet) of lawn. husqvarna robotic lawn mower
