back to article Wanna build an AI robot? Don't have an actual robot yet? Try this Holodeck for droids

OpenAI today updated Gym – its system for training intelligent software – so that developers can teach physical robots to hold pens, pick up and move objects, and so on. Gym was launched in 2016, and is a toolkit for teaching programs new tricks, such as playing Atari games and balancing poles, via reinforcement learning (RL …

    Finally!

    I've been hearing about people in colleagues and unis build robots, and program them for years, all the while the robots bumping into chairs and the "creator" of them scratching heir heads. Robots are 90% a programming problem, 10% hardware.

    A robot needs to adapt to the changes in the environment. You can build an entire robot, put it in the environment, and hope the 100 ton automated tanker does not drive into a house.

    But then we got this thing call a computer, and their power got rather high many years ago. If most games cannot get AI right, what hope is there for a robot? Why waste costs into making many many designs, when you can iterate virtually, and make just a few (see SpaceX)?

      I guess you really gotta watch out for them thar heir-head colleagues ...

        Yep. Good old typos. Still another reason to show trialling something virtually is better than releasing to the public too early. ;)

    Meh

    Sounds random

    This "sparse rewards" thing may be useful in some situations, but it sounds like you are asking for trouble and more work. If it solves the problem in some unique way, you have no information on how it solved the problem (for problems which don't involve watching the result happen). If you guide it with intermediate rewards, you at least have basic ideas of how it is achieving the result, and so can pick better test cases.

    After all, shaking the wine bottle up and down a few times may well end up with the glass containing the right amount of wine. But, that doesn't sound like a desired solution - you haven't had any way to put reasonable constraints on the solution found.

      If the virtual robot shakes the champagne bottle up and down until the cork pops and some liquid ends up in the glass... then the virtual robot clearly wants to drive F1 cars when it grows up!

      My joking aside, that's an interesting point; it sounds like our (incomplete/poor) understanding of many biological systems. We understand that it is working but we don't know how.

      Biological systems, from DNA to nervous systems, have arrived at their current state through many iterative process.

    Star Trek?

    This is clearly the first step to The Thirteenth Floor.

      It's AI Gym, not as we know it

        @ Fruit and Nutcase:

        Nice! That is some quality stuff. Shame I have but one upvote to give you.

          ...Thanks!

          And Thanks too to The Firm, for Star Trekkin'.

          This is the second time recently that I've had to opportunity to lift a line or two from Star Trekkin'. And in both cases, I'd omitted to mention them. So now I have.
