(17,469 posts)which means they must either be tethered to a plug, or haul around a battery which limits their operational time. We can make batteries bigger, but that means greater bulk and weight. Robots work fine in controlled environments with flat floors and predictable, well-defined tasks. Change any of these parameters and failure rates climb.
Again, go back to the article I mention above. The most sophisticated computer on the planet, weighing thousands of pounds can't look at a picture and tell you what it is, it can only guess with varying degrees of (un)certainty. Technology is NOT going to solve these problems anytime soon. We have been trying for half a century, and while we have taught computers some neat tricks, we are still light years away from anything actually simulating even the most basic mind.
