我们提出了一种简单的模仿学习程序,用于学习可以在非常具有挑战性的地形上行走的运动控制器。我们使用轨迹优化(TO)在程序生成的地形上生成大量轨迹数据集,并使用强化学习(RL)来模仿这些轨迹。我们通过 ANYmal 机器人的真实模型证明,学习的控制器可以转移到看不见的地形,并提供有效的初始化,以便在需要外感知和精确脚部放置的挑战性地形上进行微调。我们的设置以简单的方式结合了 TO 和 RL,克服了前者的计算限制和对鲁棒跟踪控制器的需求,以及后者的探索和奖励调整困难。
We propose a simple imitation learning procedure for learning locomotion controllers that can walk over very challenging terrains. We use trajectory optimization (TO) to produce a large dataset of trajectories over procedurally generated terrains and use Reinforcement Learning (RL) to imitate these trajectories. We demonstrate with a realistic model of the ANYmal robot that the learned controllers transfer to unseen terrains and provide an effective initialization for fine-tuning on challenging terrains that require exteroception and precise foot placements. Our setup combines TO and RL in a simple fashion that overcomes the computational limitations and need for a robust tracking controller of the former and the exploration and reward-tuning difficulties of the latter.
