Imitation learning

Last month, we showed an earlier version of this robot where we’d trained its vision system using domain randomization, that is, by showing it simulated objects with a variety of color, backgrounds, and textures, without the use of any real images. Now, we’ve developed and deployed a new algorithm, one-shot imitation learning, allowing a …
