Maybe this kind of thing does already exist..........but I dunno about it........so I would like to have the Lawn Mover with Distant Control.

Here is a picture how it would work....it's a hot day..........and you are sitting in the shadow on the armchair with the glass of lemonade........and you the distant contolr in ur hand.......and your lawn mower is cutting the grass in the direction you choose simply by using the buttons :) Cool right?
