News Raspberry Pi Mows Your Lawn So You Don’t Have To

Haaa.....the local Wayside Restaurant "It's worth the drive!!!" is using one of these for the first time this year. If it wasn't one of these, it was a very similar one.
I just happened to see it in operation and another observer explained what it was and pointed out the charging station.
Very cool!
 
Looks interesting - also as a platform for a Robot. I have found in the RPi Club I have, that the simple Robots lose interest very quickly if not programmable and are able to add HW and SW.

I am no fan of YouTube and dislike using it.

How much would it cost? Hopefully that when it goes on sale, all components are included and one does not need to 3D Print anything. I have no 3D Printer and will not be buying one.
