Curiosity Rover Decides, By Itself, What To Investigate On Mars (sciencemag.org) 73

Posted by BeauHD from the autonomous-robots dept.
sciencehabit writes: NASA's Curiosity rover landed on Mars in 2012, in part to analyze rocks to see whether the Red Planet was ever habitable (or inhabited). But now the robot has gone off script, picking out its own targets for analysis -- precisely as planned. Last year, NASA scientists uploaded a piece of software called Autonomous Exploration for Gathering Increased Science (AEGIS) adapted from the older Opportunity rover. Curiosity can now scan each new location and use artificial intelligence to find promising targets for its ChemCam. Compared with the estimated 24% success rate of random aiming at picking out outcrops -- a prime target for investigation -- the current version of AEGIS lets the rover find them 94% of the time, researchers report.

      Headline claimed that the 'success rate' is 94% Went to read the summary to find out what the 94% is all about but unfortunately it isn't saying much Any clue? SVP?

          Well, yes. Rice is not a prime candidate for cultivation on Mars, even hardy winter crops like aman.

    gone off script, picking out its own targets for analysis -- precisely as planned

    If that was planned, then by definition it's not off script. If a music score says "imrovise" or a sc-fi script says "// technobabble here" then that's what was planned.

    • Don't be silly. This is fully Turing deterministic free will on the part of the cpu in the rover.

      It is worse than that. If a music script says "improvise", or a sci-fi script says "technobabble", one can do anything, using creativity, deliberation, whatever and however. All the rover is doing is operating according to pre-defined algorithms -- defined by the programmers. There is nothing "autonomous" about it.

            These were called "Expert Systems" back then and while they worked on smaller Databases and had to be fed pre-translated data, they were not conceptionally different to Watson.

            • I wrote Expert Systems. They were simple decision trees and algorithms. Just like Watson.

                The cool thing about Watson is that you can feed in documents in natural language. The other is its scale. A well-maintained Watson "state" for a specific area is extremely useful for looking things up fast and with high accuracy and completeness. As such it can save an export a lot of time when analyzing things. But it cannot do your thinking for you and IBM does not claim that. Last statement I heard from am IBM expert was "certainly not in the next 50 years and after that, who knows". As these people rea
