While this is not a new project it is the first season my project is using
Arduino's as a main controller, past seasons have used a PC as a controller.
I'm using a Mega, and a Nano in the device, then a Nano in the remote controller and
a Nano connected to my Home PC for when shoveling snow.
the complete build is documented at: complete build
That's a very cool project. Thanks for sharing!

Idea for further development: replace the remote controller by autonomous system like robotic vacuum cleaner is.
Budvar10, I did go that route for my lawn mower.
mower topic(not Arduino controlled so off topic here):mower topic
but, it's a lot more fun for me to play in the snow using the FPV approach.

As an Arduinoist I will give my full respect, specially 'cos I've been building one of my own but I've still loved to lawn grass and plow snow by myself too much so I've kept my AutoLwn back, for now

TommiP, I also enjoy completing simple tasks like mowing grass and removing snow&Ice,
which is in sharp contrast of the demands of the work-a-day world. but each of these tasks
comes with some baggage , mowing with it's heat ,bugs, and noise. snow with it's dangerous
cold and falling risks(added because I'm getting old). that's why I think FPV is the best approach
for these types of repetitive tasks. best of both worlds, hands on completion of a task, in the
comfort of home(Sweet!).
