Bridging the 'reality gap' that separates simulated robotics from experiments\non hardware could accelerate robotic research through improved data\navailability. This paper explores domain randomization, a simple technique for\ntraining models on simulated images that transfer to real images by randomizing\nrendering in the simulator. With enough variability in the simulator, the real\nworld may appear to the model as just another variation. We focus on the task\nof object localization, which is a stepping stone to general robotic\nmanipulation skills. We find that it is possible to train a real-world object\ndetector that is accurate to 1.5cm and robust to distractors and partial\nocclusions using only data from a simulator with non-realistic random textures.\nTo demonstrate the capabilities of our detectors, we show they can be used to\nperform grasping in a cluttered environment. To our knowledge, this is the\nfirst successful transfer of a deep neural network trained only on simulated\nRGB images (without pre-training on real images) to the real world for the\npurpose of robotic control.\n
