Pat I'd suspect having long legs might be a means of keeping dust out of the joints. Whereas the wheel would tend to be ground up by the unweathered dust and grit as it works its way into the hub. On the other hand, extra lub for the wheel hubs might take care of that problem. I guess I am thinking of a large robotic ant with large wings for solar collection. This is just my half baked vision of things to come......Trig |

The legs would have to be automated somehow because of the time lag in communicating with it to prevent it from falling over. This is interesting. I'm not sure about the 1000 days, but I'm not privy to what JSC has been up to. Anthropomorphic makes sense when you think about it from the controller's perspective. I sort of know how my autonomous and non-autonomous nervous systems respond to two legged and two armed systems. I'm not sure as a human being how I'd best teleoperate an eight-legged system or even a six wheeled system. Think of it from the tele-operators perspective. As far as the comm time lag goes, I'd mentioned a good way to deal with that many many posts ago, using active resistance feedback to provide a way to slow our own ground based motions to match those of the device on the moon. Another item to consider. Sending up lab equipment so that our robot can do experiments on the moon. It might be easier/cheaper/simpler to modify existing Earth based human operated lab equipment to deal with an anthropomorphic robot on the moon rather than start from scratch with some kind of eight legged, four wheeled or even snake like robot. Also think of it as a way to get good at designing equipment that eventually could be dual-purposed and used by humans on the moon as well. This is the back-door way back to the moon that doesn't hog up all of NASA's budget trying to do it. I like it. As for active balancing, put the gyroscopic feedback into a tilt table the human has to ride back on Earth. Or better yet a 3-axis moving platform the operator 'rides'. The robot falls down, the operator pitches forward face down in the three axis harness. Dave |

From dinosaurs to humans, it's a persistant pattern across different species, time and environments. Life quickly found the optimum and locked it in, it would appear. People that sadly think life is only a fluke of chance, more an accident than anyting else, haven't noticed that randomness or mutations allow life to fully explore the possibility space, so that selection can more effectively take place. Random events, or mutations, are a one of two primary driving forces for evolution, the other is persistant order, for example four limbs and two eyes. When the two are in an equilibrium with each other so that neither dominates the whole, the system spontaneously starts hill-climbing or evolving towards higher order. Evolution is a directed path, not a random walk towards ever higher order. Increasing order, or creation, is a fundamental property of The Universe. Science and religion are both half right, and half wrong. So each grades out at 50% with is flunking the test of understanding reality. There is indeed a 'plan' for Creation, but it's a fundamental law of the universe. Like any other. .. Emergence and Evolution - Constraints on Form http://www.calresco.org/emerge.htm This looks like Program Funding Via Flash to me. Making your teleoperated robot anthropomorphic is great for SF, but for actual exploration it probably makes better sense to optimize form to something 8 legged that's designed so it can always right itself, with a couple of the legs having 'tool adapters' to use specially designed tools housed in the body. Of course, if people aren't going, why bother with the teleoperated robots? And what next, selling time to let 'everyman' operate one for a while? This isn't science. It's theater. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.

The way they have it designed it has to kneel down to pick up a rock sample. And what's with the mouth on the head in a airless vacuum? It certainly isn't going to be doing much talking up there.
