I have a robot lawn mower that is wire guided. Instead of the traditional lawn mowers that basically cut the grass in all directions (making a sloppy cut pattern) my mower knows how to cut in straight lines so you get a traditional cut pattern. It also has the ability to dump the grass cuttings into a composting bin.

Basically, I put down wire guide cable into the lawn and into the cement as well. It is all powered by electricity and has a little docking station. When it is scheduled to cut it simply rolls out, goes to the lawn and starts cutting on. After a pre-determined point, it will go back to the compost bin to dump the grass cuttings before going back to cut the lawn again. After it is done with all the cuts it simply returns back to the charging station.

I am trying to add better features to it like weather detection. If rain is scheduled then it will cut the lawn early and then delay cutting it again until the lawn is dry. I am also working on adding an edger component and a weed wacker competent so it can handle those tasks as well. Pretty much, my goal is to have a fully automated robot lawn mower when I am done with this project. So far it only cuts the grass and dumps the waste. I think this wire guided method is far superior to the autonomous robot mowers because most people's yards are in static arrangements that rarely change. So it is better to just add in the wire permanently so you get a perfect cut every time.
