Segway launches a robot lawnmower
Segway launches its first robot lawnmower, and it doesn't require a boundary wire. The Navimow uses GPS to stay on your lawn and only trim the grass you need it to trim.
According to the company, the robot mower uses Exact Fusion Locating System to keep its "precise positions and systematic mowing patterns." It can hold its position accurately to within two centimetres. If the GPS signal is temporarily weak, the Navimow has sensors that can help it keep moving and mowing.
