The LawnBot is completely not connected to iRobot’s victorious and ground-breaking success, although it does contribute to analogous features. Operating alone by means of its preprogrammed logical computer and a outer limits cable, the LawnBot can mow up to three separate sectors totaling 33,000 square feet and then return itself to its recharging dock.The perimeter cable provides the LawnBot’s computer with necessary lawn dimensions thanks to faint signal that it transmits directly to the unit. LawnBot can still mow without this signal, but a fence or small border must enclose the working area at least 4 inches tall. And when it runs into an uneven grass surface, of thicker or taller grass, the program will begin a technique of spiraling spiral outward from that area to even out grass height and eliminate any missed areas.
