Damn, 800,000 grasp attempts? Pretty nuts that they need this many... but I guess without tactile feedback, only relying on visual feedback you need this many attempts to get it right.

Do cutting-edge robots still not incorporate tactile feedback?

  I am sure that many do have tactile feedback, but every touch switch or pressure sensor is a subsytem that you must decide is worth the added complexity. I doubt any simple approach works as well has human skin. As always, the thing that gets better fastest is the computing. The mechanics and the sensors improve too -- but according to a slower set of laws.

Babies take a while to learn how to grasp things, it's believable that the number of attempts they make is in the 10,000s. 1 grasp attempt a minute, 8 hours a day for 3 months is 43,000 attempts. Of course they are learning a lot of other stuff at the same time so it's not really comparable.

  Well, it's a hard problem. Looking at the data, could you come up with a way to learn control more quickly? Ie, given a series of pixel intensities, could you send commands to each motor to get them to grasp something?

  This is something that I think people often miss when they compare machine learning to human performance. Humans spend a LOT of time in their early learning and calibrating phase. Like, it's our full time job, 365 days a year, for several years. One interaction every ~5sec, for 12 hours a day, seems a modest estimate. That's over 3 million training examples per year.

    You also have things like horses, which are running about 30 minutes after birth at speeds about half of what they can do as adults. Before an hour is out they can jump without falling. Not sure how many training examples you can squeeze in there, but not many. Perhaps 1000 ? A horse will try to stand up less than 5 minutes after birth and will only fail to stand up 5-10 times.
