Instead of having only a single physical robot, what if you had a virtual (unity3d?) robot.
I imagine you could speed up the learning process immensely if you didn&#x27;t have to have a ~200k robot actually manually performing the tasks.  Just do the physics simulation and fake the sensors and other inputs.  I&#x27;m sure that&#x27;s a pain to set up, but probably way more effective and cheaper in the long run than trying to train a single PR2<p>This was done a long time ago on a smaller scale:<p><a href="http:&#x2F;&#x2F;www.demo.cs.brandeis.edu&#x2F;pr&#x2F;neural_controllers&#x2F;evo_control.html" rel="nofollow">http:&#x2F;&#x2F;www.demo.cs.brandeis.edu&#x2F;pr&#x2F;neural_controllers&#x2F;evo_co...</a><p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;0fg1Jj8ehHs" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;0fg1Jj8ehHs</a><p><a href="http:&#x2F;&#x2F;youtu.be&#x2F;n6uMBveqbyE" rel="nofollow">http:&#x2F;&#x2F;youtu.be&#x2F;n6uMBveqbyE</a><p>I&#x27;d love to see something like that tried with more modern computers &#x2F; neural algorithms.  Does anyone know places that are actually doing this?
