NASA's Upcoming 'Super Bot Ball' Might Drop Onto Saturn's Titan

The unconventional lander uses a learning algorithm to move about.


The most difficult part of any space mission is the landing. If anything goes wrong, it's most likely going to be there. When the Curiosity rover landed on Mars, it was lowered via a winch on a rocket-propelled platform. Now, NASA's looking at a completely different strategy. Called the "Super Bot Ball", it's a jumble of poles and wires that can survive an orbital landing with a payload and still explore the rocky wilderness of alien planets.

The Super Bot Ball uses a series of interlocking rods and cables, using structures known as "tensegrities". There's not a rigid connection in the entire device, which allows it to absorb the full impact of an orbital drop and keep going, while still carrying a payload of fragile sensors safely suspended in the middle.

Of course, controlling such a contraption isn't as straightforward as the typical rover. To compensate, engineers are developing learning systems so it can pilot itself. The process is similar to evolution, where bad ideas are tossed out in favor of more efficient ones. Eventually, when given a task, the idea is that the bot will know which wires and poles to flex to best maneuver there. It might even be possible to drop dozens, or hundreds of these bots on a planet and have them all learn together.

The project is still in the early stages, but NASA intends for it to drop on Saturn's moon [a href=http://www.sciencerecorder.com/news/nasas-super-ball-bot-to-conquer-space-exploration/]Titan[/a] first. It's an intriguing idea that seems much more fit to handle the unknown than the traditional wheel-and-tread rovers. Plus, it looks like a tangled Katamari, which is always a good thing.

Not sure how that works with Titan. Landing there itself isn't so tough, with low gravity and a high density atmosphere. But its dense atmosphere is very cold. Landers freeze to death.

Somebody's sure to ask, "Why are they freezing there and not in deep space?" Space near Saturn may indeed be very cold, but it's not dense. In fact, it's density is so low it might as well be zero. Heat transfer is very density sensitive (which is why water tends to feel much colder than air at the same temperature).

Wow, sounds like it's gonna be one hell of an attack on titan.


It'll be interesting to see how this pans out.

...or just have them gain sentience, build infrastructure, and launch an assault on earth a few hundred years later. Nothing like dropping machines capable of learning into an unsupervised environment.

Now, something about that title just confused the hell out of me. I thought I was clicking on the fallout news link, and when I read "Super Bot Ball" and "Saturn" I thought it was a console launch of some kind.
