Magical Thinking: A Roomba to clean up horse poop

I am so happy I could weep.
I got a Roomba this weekend. Anything that automatically vacuums my floors for me without tiring or complaining ... well ... sigh ... what can a girl say?
I'm in love.
And this has gotten me to thinking. Do you think anyone has thought of developing such a robotic device to clean up horse manure? I mean, can you imagine? A slave robot sweeping every corner of your pasture until it's sparkling clean. Perhaps even programmed to clean up immediately upon the horse's production of a big, steaming pile of gooey green horse poop on the ground? It would have to be small enough to vacuum the manure from stalls too. Or possibly that would be an attachment or another model altogether. It could come in different sizes, depending upon what size horse you have. Miniature. Pony. Cob. Horse. Draft.
Ooooh, I think I'm onto something here. What would we call it?
A Poopa? A Manu-R-oomba? Horse-Shit-o-Roomba?
I'd better call the patent office quick before some other savvy horseperson beats me to the punch. I know ... when unicorns fly.
