Why isn't there an iRobot for dog poo and other yard debris? We have robot lawn mowers, can't we at least have a machine that scoops up sticks, pine cones, poops, and other small items? Can't something like that make like a small pile or mound of yard refuse? It just seems like we are hanging out like a bunch of cavemen scooping up poop with a poop scooper when we should be living life like the Jetsons with robots that do our bidding.
