It's so easy to design vehicles that can't roll over on their backs and die like a turtle. All you need to do is use large wagon-wheels and put the cargo/payload near the axles of it, where it doesn't extend above the top of the wheel. Then the device can continue to work as well upside down as right-side-up. In other words, it has no such thing as upside down. There are lots of robots like this now, where if they get upside down, the wheels are on 'arms' that can just swing to the other side to make it right-side-up again. Admittedly I'm a mechanical engineer myself, but this design doesn't seem like "Rocket Science" to me. haha. (nice pun amirite)
