What is the Robot Lawn 100m Mower Boundary Wire?
The Robot Lawn Mower 100m Boundary Wire is used in conjunction with the robotzoo Wombat Charging Stations and Wombat Joey Charging Stations. There is also a Robot Lawn Mower Boundary Wire 300m Spool available from robotzoo. Its purpose is to mark an electronic boundary to the lawn area covered by the robot mowers. By making sure that the mower stays within a designated boundary, safety is ensured.Boundary Wire is connected to +ve/-ve DC terminals on the charging station as shown in the instruction manual. It is laid (pegged) on top of the lawn, or buried just underneath the surface. This is done within 30cm inside the boundary of the lawn area to be mown. The wire carries a low (5V) current, which creates a small magnetic field that can be detected by sensors on the mowers themselves. The mowers are programmed to detect when they cross over the boundary wire, and then change direction to return to the mowing area. They are also programmed to follow the boundary wire back to the charging station when they need to recharge. If the boundary wire is broken or cut, the base station will sound an alarm, and the mower will not operate in automatic mode. (It can still be made to operate in manual mode). Our Boundary wire is made from true copper (TC) strands. Other cheaper brands are made from tinned copper coated aluminium (TCCA). Copper is a far superior conductor to aluminium, so there is less gain (current) lost over a given length. This means that the length of boundary wire supported by the base station can be longer. Our base stations can support up to 600m of wire.
