Robotic

Folks in a cottage on the CooriedogWalk have got themselves a robotic mower. It (we had a disputes over gender) tootles about at night cutting away. If it senses rain it makes its way back to the docking station and waits. If it is running low on power it goes back and plugs itself in. Amazing.
One or two mornings we have found it beyond the grass, waiting until someone puts it back. Then you wonder which is the intelligent one.
