A new learned legged locomotion study uses massive parallelism on a single GPU to get robots up and walking on flat terrain in under four minutes, and on uneven terrain in twenty minutes. Although deep reinforcement learning (DRL) has achieved impressive results in robotics, the amount of data required to train a policy increases dramatically with task complexity. One way to improve the quality and time-to-deployment of DRL policies is to use massive parallelism. In the paper Learning to Walk in Minutes Using Massively Parallel Deep Reinforcement Learning, a research team from ETH Zurich and NVIDIA proposes a training framework that enables fast policy generation for real-world robotic tasks using massive parallelism on a single workstation GPU. Compared to previous methods, the approach can reduce training time by multiple orders of magnitude.
