Jeff how would you feel about unmanned bombers? With AI controllers taking off and landing on aircraft carriers? I feel they're off-topic for this newsgroup, but I'll quickly respond and try to keep it somewhat on-topic. I don't believe that AI controlled unmanned aircraft (e.g. bombers) exist yet. *There is nothing approaching an AI on any currently operational remotely operated vehicles. *They're controlled by pilots in a control room. *As an example, here is an example of an MQ-1 Predator control room: http://commons.wikimedia.org/wiki/Fi...trols_2007-08- 07.jpg The intelligences in the picture look awfully human to me. Jeff On the CBS news a couple nights ago. The military has a indenpentendly operated drone that is being launched and recovered by aircraft carriers, its not remote controlled.. so far its going to be used for reconaisance, but is totally capable of being used for as a bomber. if i get some time later i will look around for a link. its shape is a stealth bomber appearance, but they didnt give the dimensions. the advantage, current manned vehicles weakest links are the humans that fly them, max G forces and such. unmanned wouldnt have those limitations. the military also likes that no pilot is put at risk to fly it...... what makes this on topic here? not only is it amazing, but it shows how far artifical intelligence has come, the next use may well be on mars where with enough power the rover could operate continiously......for a fraction the cost of manned missions the future is now |

There is *nothing* like an AI which is cheap enough, powerful enough (processing wise), miserly with power, and creative enough to actually handle the unexpected on Mars. Mind you, we had had unmanned craft land on the moon before Apollo 11: Surveyor, Lunokhod. They represented efforts to find out enough about the surface to know if humans could land there. They certainly weren't mass produced, though, nor inexpensive, and landing them involved a lot of luck. And we didn't find out much more about the moon than confirming the gravitational acceleration (on earth, we call that 'g') and determining a little of the surface texture (sand? dust? solid rock?). /dps -- "This is all very fine, but let us not be carried away be excitement, but ask calmly, how does this person feel about in in his cooler moments next day, with six or seven thousand feet of snow and stuff on top of him?" _Roughing It_, Mark Twain. |

Opportunity toaster:( has traveled 22 mars miles
CBS News) The technology behind drones is developing rapidly. Today,
drones used to attack targets are flown by remote control by pilots on the ground. But a new generation has no pilot at all. They can be completely guided by computer. A new type of vehicle being developed by the Navy looks like stealth bomber and could probably carry 4,000 pounds of weapons, but there's no pilot in the cockpit. Navy Capt. Jaime Engdahl is director of what's called the X-47B Project. "It is an autonomous vehicle so it's flying itself ... It's a very unique aircraft," Engdahl said. Watch: Brennan: Drones only used as "last resort" Amid protests, Brennan defends drone program Brennan, White House under fire for drone policy This afternoon, responding to a computer program, the X-47B launched from a land-based catapult at a Navy test facility in Maryland. "The test went very well and it's very significant because this is the first time we're actually doing catapult shots with a vehicle with nobody in the cockpit," Engdahl said. The X-47B has already performed taxi tests aboard the USS Truman and will soon attempt the first unmanned take off and landing from an aircraft carrier. "We're working the carrier schedules right now so sometime this spring or summer [the drone will take off and land on a carrier]," Engdahl said. |
