I agree, Sailor, that we need to get "people into space" in a meaningful way. Private companies are already working on it, from tourism to mining, which are the most notable enterprises with enough "profit motivation" to make them feasible. (And if we don't solve our "dearth of rare earth minerals" dilemma soon, maybe space-mining will be the way to go.)
And there are problems with "space-bots", from perception to technology. Sending a 'bot to Mars has the expectation that they will resemble Man in order to accomplish all of Man's tasks. But the technology isn't there, and the intermediate step - of observing moon bot-miners and operating them thru Wii "same movement" technology - wouldn't work on Mars, since we couldn't observe/direct them in real-time.
Sending multiple "special task" robots to Mars, would only add to the craft weight and fuel consumption. And trying to "run" multiple different 'bots on another planet, would be a gigantic headache for ground control, whether JPL or private.
