    While it is certainly natural for all living creatures to learn to cope with an injury, I think this is far more important for robots, since they don't have a survival instinct.

    Humans will go to great lengths to avoid getting injured (well, most sane ones). However, robots will just do what they are told. While they may be told to avoid any hazards, they just don't have that instinct that says I *really* don't want to get my limb chopped off today.

    So to compensate, all robots in hazardous or isolated situations should have this self-healing built in, as well as redundant limbs. A robot could be built with 2 legs, but why not make it 4 or 6 and have a couple to spare. The same goes for sensors. Only two are needed for stereoscopic vision, but 4 or 6 would be better.

    That said, nothing in the article suggests there is anything remarkable about the robot. The most telling line in the article is "Adam was activated with a basic level of competence, which let him know to back off if he hit a wall, and to feed when he saw a flower." That's two very important abilities Adam didn't have to learn.

For example, Cyc knows that trees are usually outdoors, that once people die they stop buying things, and that glasses of liquid should be carried rightside-up."

    And of course, lots of little other things, like targeting systems, healing systems (like this article), a CNS to link these higher-level functions to the motor control systems of the robot, um.... GUNS, MISSLES, etc..

    Yeah, maybe not such a good idea. Of course, if we truly believed it a bad idea, we'd work for treaties now against robotic warfare, before one of our county's governments builds these and the rest are "forced" to catch up.
